2020/09/30 - Amazon Simple Storage Service - 12 updated api methods
Changes Amazon S3 on Outposts expands object storage to on-premises AWS Outposts environments, enabling you to store and retrieve objects using S3 APIs and features. Support S3 on Outposts Access Point and Bucket ARNs
{'StorageClass': {'OUTPOSTS'}}
Creates a copy of an object that is already stored in Amazon S3.
Note
You can store individual objects of up to 5 TB in Amazon S3. You create a copy of your object up to 5 GB in size in a single atomic operation using this API. However, to copy an object greater than 5 GB, you must use the multipart upload Upload Part - Copy API. For more information, see Copy Object Using the REST Multipart Upload API .
All copy requests must be authenticated. Additionally, you must have read access to the source object and write access to the destination bucket. For more information, see REST Authentication . Both the Region that you want to copy the object from and the Region that you want to copy the object to must be enabled for your account.
A copy request might return an error when Amazon S3 receives the copy request or while Amazon S3 is copying the files. If the error occurs before the copy operation starts, you receive a standard Amazon S3 error. If the error occurs during the copy operation, the error response is embedded in the 200 OK response. This means that a 200 OK response can contain either a success or an error. Design your application to parse the contents of the response and handle it appropriately.
If the copy is successful, you receive a response with information about the copied object.
Note
If the request is an HTTP 1.1 request, the response is chunk encoded. If it were not, it would not contain the content-length, and you would need to read the entire body.
The copy request charge is based on the storage class and Region that you specify for the destination object. For pricing information, see Amazon S3 pricing .
Warning
Amazon S3 transfer acceleration does not support cross-Region copies. If you request a cross-Region copy using a transfer acceleration endpoint, you get a 400 Bad Request error. For more information, see Transfer Acceleration .
Metadata
When copying an object, you can preserve all metadata (default) or specify new metadata. However, the ACL is not preserved and is set to private for the user making the request. To override the default ACL setting, specify a new ACL when generating a copy request. For more information, see Using ACLs .
To specify whether you want the object metadata copied from the source object or replaced with metadata provided in the request, you can optionally add the x-amz-metadata-directive header. When you grant permissions, you can use the s3:x-amz-metadata-directive condition key to enforce certain metadata behavior when objects are uploaded. For more information, see Specifying Conditions in a Policy in the Amazon S3 Developer Guide . For a complete list of Amazon S3-specific condition keys, see Actions, Resources, and Condition Keys for Amazon S3 .
** x-amz-copy-source-if Headers**
To only copy an object under certain conditions, such as whether the Etag matches or whether the object was modified before or after a specified date, use the following request parameters:
x-amz-copy-source-if-match
x-amz-copy-source-if-none-match
x-amz-copy-source-if-unmodified-since
x-amz-copy-source-if-modified-since
If both the x-amz-copy-source-if-match and x-amz-copy-source-if-unmodified-since headers are present in the request and evaluate as follows, Amazon S3 returns 200 OK and copies the data:
x-amz-copy-source-if-match condition evaluates to true
x-amz-copy-source-if-unmodified-since condition evaluates to false
If both the x-amz-copy-source-if-none-match and x-amz-copy-source-if-modified-since headers are present in the request and evaluate as follows, Amazon S3 returns the 412 Precondition Failed response code:
x-amz-copy-source-if-none-match condition evaluates to false
x-amz-copy-source-if-modified-since condition evaluates to true
Note
All headers with the x-amz- prefix, including x-amz-copy-source , must be signed.
Encryption
The source object that you are copying can be encrypted or unencrypted. The source object can be encrypted with server-side encryption using AWS managed encryption keys (SSE-S3 or SSE-KMS) or by using a customer-provided encryption key. With server-side encryption, Amazon S3 encrypts your data as it writes it to disks in its data centers and decrypts the data when you access it.
You can optionally use the appropriate encryption-related headers to request server-side encryption for the target object. You have the option to provide your own encryption key or use SSE-S3 or SSE-KMS, regardless of the form of server-side encryption that was used to encrypt the source object. You can even request encryption if the source object was not encrypted. For more information about server-side encryption, see Using Server-Side Encryption .
Access Control List (ACL)-Specific Request Headers
When copying an object, you can optionally use headers to grant ACL-based permissions. By default, all objects are private. Only the owner has full access control. When adding a new object, you can grant permissions to individual AWS accounts or to predefined groups defined by Amazon S3. These permissions are then added to the ACL on the object. For more information, see Access Control List (ACL) Overview and Managing ACLs Using the REST API .
Storage Class Options
You can use the CopyObject operation to change the storage class of an object that is already stored in Amazon S3 using the StorageClass parameter. For more information, see Storage Classes in the Amazon S3 Service Developer Guide .
Versioning
By default, x-amz-copy-source identifies the current version of an object to copy. If the current version is a delete marker, Amazon S3 behaves as if the object was deleted. To copy a different version, use the versionId subresource.
If you enable versioning on the target bucket, Amazon S3 generates a unique version ID for the object being copied. This version ID is different from the version ID of the source object. Amazon S3 returns the version ID of the copied object in the x-amz-version-id response header in the response.
If you do not enable versioning or suspend it on the target bucket, the version ID that Amazon S3 generates is always null.
If the source object's storage class is GLACIER, you must restore a copy of this object before you can use it as a source object for the copy operation. For more information, see RestoreObject .
The following operations are related to CopyObject :

string
[REQUIRED]
The name of the destination bucket.
When using this API with an access point, you must direct requests to the access point hostname. The access point hostname takes the form AccessPointName -AccountId .s3-accesspoint.*Region* .amazonaws.com. When using this operation using an access point through the AWS SDKs, you provide the access point ARN in place of the bucket name. For more information about access point ARNs, see Using Access Points in the Amazon Simple Storage Service Developer Guide .
When using this API with Amazon S3 on Outposts, you must direct requests to the S3 on Outposts hostname. The S3 on Outposts hostname takes the form AccessPointName -AccountId .*outpostID* .s3-outposts.*Region* .amazonaws.com. When using this operation using S3 on Outposts through the AWS SDKs, you provide the Outposts bucket ARN in place of the bucket name. For more information about S3 on Outposts ARNs, see Using S3 on Outposts in the Amazon Simple Storage Service Developer Guide .
string
Specifies caching behavior along the request/reply chain.
string
Specifies presentational information for the object.
string
Specifies what content encodings have been applied to the object and thus what decoding mechanisms must be applied to obtain the media-type referenced by the Content-Type header field.
string
The language the content is in.
string
A standard MIME type describing the format of the object data.
string
[REQUIRED]
Specifies the source object for the copy operation. You specify the value in one of two formats, depending on whether you want to access the source object through an access point :
For objects not accessed through an access point, specify the name of the source bucket and the key of the source object, separated by a slash (/). For example, to copy the object reports/january.pdf from the bucket awsexamplebucket , use awsexamplebucket/reports/january.pdf . The value must be URL encoded.
For objects accessed through access points, specify the Amazon Resource Name (ARN) of the object as accessed through the access point, in the format arn:aws:s3:<Region>:<account-id>:accesspoint/<access-point-name>/object/<key> . For example, to copy the object reports/january.pdf through access point my-access-point owned by account 123456789012 in Region us-west-2 , use the URL encoding of arn:aws:s3:us-west-2:123456789012:accesspoint/my-access-point/object/reports/january.pdf . The value must be URL encoded.
Note
Amazon S3 supports copy operations using access points only when the source and destination buckets are in the same AWS Region.
Alternatively, for objects accessed through Amazon S3 on Outposts, specify the ARN of the object as accessed in the format arn:aws:s3-outposts:<Region>:<account-id>:outpost/<outpost-id>/object/<key> . For example, to copy the object reports/january.pdf through outpost my-outpost owned by account 123456789012 in Region us-west-2 , use the URL encoding of arn:aws:s3-outposts:us-west-2:123456789012:outpost/my-outpost/object/reports/january.pdf . The value must be URL encoded.
To copy a specific version of an object, append ?versionId=<version-id> to the value (for example, awsexamplebucket/reports/january.pdf?versionId=QUpfdndhfd8438MNFDN93jdnJFkdmqnh893 ). If you don't specify a version ID, Amazon S3 copies the latest version of the source object.

The key must be appropriate for use with the algorithm specified in the x-amz-server-side-encryption-customer-algorithm header.
string
Specifies the 128-bit MD5 digest of the encryption key according to RFC 1321. Amazon S3 uses this header for a message integrity check to ensure that the encryption key was transmitted without error.
string
Specifies the AWS KMS key ID to use for object encryption. All GET and PUT requests for an object protected by AWS KMS will fail if not made via SSL or using SigV4. For information about configuring using any of the officially supported AWS SDKs and AWS CLI, see Specifying the Signature Version in Request Authentication in the Amazon S3 Developer Guide .

{'StorageClass': {'OUTPOSTS'}}
This operation initiates a multipart upload and returns an upload ID. This upload ID is used to associate all of the parts in the specific multipart upload. You specify this upload ID in each of your subsequent upload part requests (see UploadPart ). You also include this upload ID in the final request to either complete or abort the multipart upload request.
For more information about multipart uploads, see Multipart Upload Overview .
If you have configured a lifecycle rule to abort incomplete multipart uploads, the upload must complete within the number of days specified in the bucket lifecycle configuration. Otherwise, the incomplete multipart upload becomes eligible for an abort operation and Amazon S3 aborts the multipart upload. For more information, see Aborting Incomplete Multipart Uploads Using a Bucket Lifecycle Policy .
For information about the permissions required to use the multipart upload API, see Multipart Upload API and Permissions .
For request signing, multipart upload is just a series of regular requests. You initiate a multipart upload, send one or more requests to upload parts, and then complete the multipart upload process. You sign each request individually. There is nothing special about signing multipart upload requests. For more information about signing, see Authenticating Requests (AWS Signature Version 4) .
Note
After you initiate a multipart upload and upload one or more parts, to stop being charged for storing the uploaded parts, you must either complete or abort the multipart upload. Amazon S3 frees up the space used to store the parts and stop charging you for storing them only after you either complete or abort a multipart upload.
You can optionally request server-side encryption. For server-side encryption, Amazon S3 encrypts your data as it writes it to disks in its data centers and decrypts it when you access it. You can provide your own encryption key, or use AWS Key Management Service (AWS KMS) customer master keys (CMKs) or Amazon S3-managed encryption keys. If you choose to provide your own encryption key, the request headers you provide in UploadPart and UploadPartCopy requests must match the headers you used in the request to initiate the upload by using CreateMultipartUpload .
To perform a multipart upload with encryption using an AWS KMS CMK, the requester must have permission to the kms:Encrypt , kms:Decrypt , kms:ReEncrypt* , kms:GenerateDataKey* , and kms:DescribeKey actions on the key. These permissions are required because Amazon S3 must decrypt and read data from the encrypted file parts before it completes the multipart upload.
If your AWS Identity and Access Management (IAM) user or role is in the same AWS account as the AWS KMS CMK, then you must have these permissions on the key policy. If your IAM user or role belongs to a different account than the key, then you must have the permissions on both the key policy and your IAM user or role.
For more information, see Protecting Data Using Server-Side Encryption .
Access Permissions
When copying an object, you can optionally specify the accounts or groups that should be granted specific permissions on the new object. There are two ways to grant the permissions using the request headers:
Specify a canned ACL with the x-amz-acl request header. For more information, see Canned ACL .
Specify access permissions explicitly with the x-amz-grant-read , x-amz-grant-read-acp , x-amz-grant-write-acp , and x-amz-grant-full-control headers. These parameters map to the set of permissions that Amazon S3 supports in an ACL. For more information, see Access Control List (ACL) Overview .
You can use either a canned ACL or specify access permissions explicitly. You cannot do both.
Server-Side- Encryption-Specific Request Headers
You can optionally tell Amazon S3 to encrypt data at rest using server-side encryption. Server-side encryption is for data encryption at rest. Amazon S3 encrypts your data as it writes it to disks in its data centers and decrypts it when you access it. The option you use depends on whether you want to use AWS managed encryption keys or provide your own encryption key.
Use encryption keys managed by Amazon S3 or customer master keys (CMKs) stored in AWS Key Management Service (AWS KMS) – If you want AWS to manage the keys used to encrypt data, specify the following headers in the request.
x-amz-server-side-encryption
x-amz-server-side-encryption-aws-kms-key-id
x-amz-server-side-encryption-context
Note
If you specify x-amz-server-side-encryption:aws:kms , but don't provide x-amz-server-side-encryption-aws-kms-key-id , Amazon S3 uses the AWS managed CMK in AWS KMS to protect the data.
Warning
All GET and PUT requests for an object protected by AWS KMS fail if you don't make them with SSL or by using SigV4.
For more information about server-side encryption with CMKs stored in AWS KMS (SSE-KMS), see Protecting Data Using Server-Side Encryption with CMKs stored in AWS KMS .
Use customer-provided encryption keys – If you want to manage your own encryption keys, provide all the following headers in the request.
x-amz-server-side-encryption-customer-algorithm
x-amz-server-side-encryption-customer-key
x-amz-server-side-encryption-customer-key-MD5
For more information about server-side encryption with CMKs stored in AWS KMS (SSE-KMS), see Protecting Data Using Server-Side Encryption with CMKs stored in AWS KMS .
Access-Control-List (ACL)-Specific Request Headers
You also can use the following access control–related headers with this operation. By default, all objects are private. Only the owner has full access control. When adding a new object, you can grant permissions to individual AWS accounts or to predefined groups defined by Amazon S3. These permissions are then added to the access control list (ACL) on the object. For more information, see Using ACLs . With this operation, you can grant access permissions using one of the following two methods:
Specify a canned ACL (x-amz-acl ) — Amazon S3 supports a set of predefined ACLs, known as canned ACLs . Each canned ACL has a predefined set of grantees and permissions. For more information, see Canned ACL .
Specify access permissions explicitly — To explicitly grant access permissions to specific AWS accounts or groups, use the following headers. Each header maps to specific permissions that Amazon S3 supports in an ACL. For more information, see Access Control List (ACL) Overview . In the header, you specify a list of grantees who get the specific permission. To grant permissions explicitly, use:
x-amz-grant-read
x-amz-grant-write
x-amz-grant-read-acp
x-amz-grant-write-acp
x-amz-grant-full-control
You specify each grantee as a type=value pair, where the type is one of the following:
id – if the value specified is the canonical user ID of an AWS account
uri – if you are granting permissions to a predefined group
emailAddress – if the value specified is the email address of an AWS account
Note
Using email addresses to specify a grantee is only supported in the following AWS Regions:
US East (N. Virginia)
US West (N. California)
US West (Oregon)
Asia Pacific (Singapore)
Asia Pacific (Sydney)
Asia Pacific (Tokyo)
Europe (Ireland)
South America (São Paulo)
For a list of all the Amazon S3 supported Regions and endpoints, see Regions and Endpoints in the AWS General Reference.
For example, the following x-amz-grant-read header grants the AWS accounts identified by account IDs permissions to read object data and its metadata:
x-amz-grant-read: id="11112222333", id="444455556666"

{'ReplicationConfiguration': {'Rules': {'Destination': {'StorageClass': {'OUTPOSTS'}}}}}
Returns the replication configuration of a bucket.
Note
It can take a while to propagate the put or delete a replication configuration to all Amazon S3 systems. Therefore, a get request soon after put or delete can return a wrong result.
For information about replication configuration, see Replication in the Amazon Simple Storage Service Developer Guide .
This operation requires permissions for the s3:GetReplicationConfiguration action. For more information about permissions, see Using Bucket Policies and User Policies .
If you include the Filter element in a replication configuration, you must also include the DeleteMarkerReplication and Priority elements. The response also returns those elements.

Rules (list) --
A container for one or more replication rules. A replication configuration must have at least one rule and can contain a maximum of 1,000 rules.
(dict) --
Specifies which Amazon S3 objects to replicate and where to store the replicas.
ID (string) --
A unique identifier for the rule. The maximum value is 255 characters.
Priority (integer) --
The priority associated with the rule. If you specify multiple rules in a replication configuration, Amazon S3 prioritizes the rules to prevent conflicts when filtering. If two or more rules identify the same object based on a specified filter, the rule with higher priority takes precedence. For example:
Same object quality prefix-based filter criteria if prefixes you specified in multiple rules overlap
Same object qualify tag-based filter criteria specified in multiple rules
For more information, see `Replication < https://docs.aws.amazon.com/AmazonS3/latest/dev/replication.html>`__ in the Amazon Simple Storage Service Developer Guide .
Prefix (string) --
An object key name prefix that identifies the object or objects to which the rule applies. The maximum prefix length is 1,024 characters. To include all objects in a bucket, specify an empty string.
Filter (dict) --
A filter that identifies the subset of objects to which the replication rule applies. A Filter must specify exactly one Prefix , Tag , or an And child element.
Prefix (string) --
An object key name prefix that identifies the subset of objects to which the rule applies.

A container for specifying a tag key and value.
The rule applies only to objects that have the tag in their tag set.
Key (string) --
Name of the object key.
Value (string) --
Value of the tag.
And (dict) --
A container for specifying rule filters. The filters determine the subset of objects to which the rule applies. This element is required only if you specify more than one filter. For example:
If you specify both a Prefix and a Tag filter, wrap these filters in an And tag.
If you specify a filter based on multiple tags, wrap the Tag elements in an And tag.

Name of the object key.
Value (string) --
Value of the tag.
Status (string) --
Specifies whether the rule is enabled.
SourceSelectionCriteria (dict) --
A container that describes additional filters for identifying the source objects that you want to replicate. You can choose to enable or disable the replication of these objects. Currently, Amazon S3 supports only the filter that you can specify for objects created with server-side encryption using a customer master key (CMK) stored in AWS Key Management Service (SSE-KMS).
SseKmsEncryptedObjects (dict) --
A container for filter information for the selection of Amazon S3 objects encrypted with AWS KMS. If you include SourceSelectionCriteria in the replication configuration, this element is required.

Status (string) --
Destination (dict) --
A container for information about the replication destination and its configurations including enabling the S3 Replication Time Control (S3 RTC).
Bucket (string) --
The Amazon Resource Name (ARN) of the bucket where you want Amazon S3 to store the results.
Account (string) --
Destination bucket owner account ID. In a cross-account scenario, if you direct Amazon S3 to change replica ownership to the AWS account that owns the destination bucket by specifying the AccessControlTranslation property, this is the account ID of the destination bucket owner. For more information, see Replication Additional Configuration: Changing the Replica Owner in the Amazon Simple Storage Service Developer Guide .
StorageClass (string) --
The storage class to use when replicating objects, such as S3 Standard or reduced redundancy. By default, Amazon S3 uses the storage class of the source object to create the object replica.
For valid values, see the StorageClass element of the PUT Bucket replication action in the Amazon Simple Storage Service API Reference .
AccessControlTranslation (dict) --
Specify this only in a cross-account scenario (where source and destination bucket owners are not the same), and you want to change replica ownership to the AWS account that owns the destination bucket. If this is not specified in the replication configuration, the replicas are owned by same AWS account that owns the source object.
Owner (string) --
Specifies the replica ownership. For default and valid values, see PUT bucket replication in the Amazon Simple Storage Service API Reference .
EncryptionConfiguration (dict) --
A container that provides information about encryption. If SourceSelectionCriteria is specified, you must specify this element.
ReplicaKmsKeyID (string) --
Specifies the ID (Key ARN or Alias ARN) of the customer managed customer master key (CMK) stored in AWS Key Management Service (KMS) for the destination bucket. Amazon S3 uses this key to encrypt replica objects. Amazon S3 only supports symmetric customer managed CMKs. For more information, see Using Symmetric and Asymmetric Keys in the AWS Key Management Service Developer Guide .
ReplicationTime (dict) --
A container specifying S3 Replication Time Control (S3 RTC), including whether S3 RTC is enabled and the time when all objects and operations on objects must be replicated. Must be specified together with a Metrics block.
Status (string) --
Specifies whether the replication time is enabled.

A container specifying replication metrics-related settings enabling metrics and Amazon S3 events for S3 Replication Time Control (S3 RTC). Must be specified together with a ReplicationTime block.
Status (string) --
Specifies whether the replication metrics are enabled.
EventThreshold (dict) --
A container specifying the time threshold for emitting the s3:Replication:OperationMissedThreshold event.
Minutes (integer) --
Contains an integer specifying time in minutes.
Valid values: 15 minutes.
DeleteMarkerReplication (dict) --
Specifies whether Amazon S3 replicates the delete markers. If you specify a Filter , you must specify this element. However, in the latest version of replication configuration (when Filter is specified), Amazon S3 doesn't replicate delete markers. Therefore, the DeleteMarkerReplication element can contain only <Status>Disabled</Status>. For an example configuration, see Basic Rule Configuration .
Note
If you don't specify the Filter element, Amazon S3 assumes that the replication configuration is the earlier version, V1. In the earlier version, Amazon S3 handled replication of delete markers differently. For more information, see Backward Compatibility .
Status (string) --
Indicates whether to replicate delete markers.
Note
In the current implementation, Amazon S3 doesn't replicate the delete markers. The status must be Disabled .
{'StorageClass': {'OUTPOSTS'}}
Retrieves objects from Amazon S3. To use GET , you must have READ access to the object. If you grant READ access to the anonymous user, you can return the object without using an authorization header.
An Amazon S3 bucket has no directory hierarchy such as you would find in a typical computer file system. You can, however, create a logical hierarchy by using object key names that imply a folder structure. For example, instead of naming an object sample.jpg , you can name it photos/2006/February/sample.jpg .
To get an object from such a logical hierarchy, specify the full key name for the object in the GET operation. For a virtual hosted-style request example, if you have the object photos/2006/February/sample.jpg , specify the resource as /photos/2006/February/sample.jpg . For a path-style request example, if you have the object photos/2006/February/sample.jpg in the bucket named examplebucket , specify the resource as /examplebucket/photos/2006/February/sample.jpg . For more information about request types, see HTTP Host Header Bucket Specification .
To distribute large files to many people, you can save bandwidth costs by using BitTorrent. For more information, see Amazon S3 Torrent . For more information about returning the ACL of an object, see GetObjectAcl .
If the object you are retrieving is stored in the GLACIER or DEEP_ARCHIVE storage classes, before you can retrieve the object you must first restore a copy using RestoreObject . Otherwise, this operation returns an InvalidObjectStateError error. For information about restoring archived objects, see Restoring Archived Objects .
Encryption request headers, like x-amz-server-side-encryption , should not be sent for GET requests if your object uses server-side encryption with CMKs stored in AWS KMS (SSE-KMS) or server-side encryption with Amazon S3–managed encryption keys (SSE-S3). If your object does use these types of keys, you’ll get an HTTP 400 BadRequest error.
If you encrypt an object by using server-side encryption with customer-provided encryption keys (SSE-C) when you store the object in Amazon S3, then when you GET the object, you must use the following headers:
x-amz-server-side-encryption-customer-algorithm
x-amz-server-side-encryption-customer-key
x-amz-server-side-encryption-customer-key-MD5
For more information about SSE-C, see Server-Side Encryption (Using Customer-Provided Encryption Keys) .
Assuming you have permission to read object tags (permission for the s3:GetObjectVersionTagging action), the response also returns the x-amz-tagging-count header that provides the count of number of tags associated with the object. You can use GetObjectTagging to retrieve the tag set associated with an object.
Permissions
You need the s3:GetObject permission for this operation. For more information, see Specifying Permissions in a Policy . If the object you request does not exist, the error Amazon S3 returns depends on whether you also have the s3:ListBucket permission.
If you have the s3:ListBucket permission on the bucket, Amazon S3 will return an HTTP status code 404 ("no such key") error.
If you don’t have the s3:ListBucket permission, Amazon S3 will return an HTTP status code 403 ("access denied") error.
Versioning
By default, the GET operation returns the current version of an object. To return a different version, use the versionId subresource.
Note
If the current version of the object is a delete marker, Amazon S3 behaves as if the object was deleted and includes x-amz-delete-marker: true in the response.
For more information about versioning, see PutBucketVersioning .
Overriding Response Header Values
There are times when you want to override certain response header values in a GET response. For example, you might override the Content-Disposition response header value in your GET request.
You can override values for a set of response headers using the following query parameters. These response header values are sent only on a successful request, that is, when status code 200 OK is returned. The set of headers you can override using these parameters is a subset of the headers that Amazon S3 accepts when you create an object. The response headers that you can override for the GET response are Content-Type , Content-Language , Expires , Cache-Control , Content-Disposition , and Content-Encoding . To override these header values in the GET response, you use the following request parameters.
Note
You must sign the request, either using an Authorization header or a presigned URL, when using these parameters. They cannot be used with an unsigned (anonymous) request.
response-content-type
response-content-language
response-expires
response-cache-control
response-content-disposition
response-content-encoding
Additional Considerations about Request Headers
If both of the If-Match and If-Unmodified-Since headers are present in the request as follows: If-Match condition evaluates to true , and; If-Unmodified-Since condition evaluates to false ; then, S3 returns 200 OK and the data requested.
If both of the If-None-Match and If-Modified-Since headers are present in the request as follows:If-None-Match condition evaluates to false , and; If-Modified-Since condition evaluates to true ; then, S3 returns 304 Not Modified response code.
For more information about conditional requests, see RFC 7232 .

{'StorageClass': {'OUTPOSTS'}}
The HEAD operation retrieves metadata from an object without returning the object itself. This operation is useful if you're only interested in an object's metadata. To use HEAD, you must have READ access to the object.
A HEAD request has the same options as a GET operation on an object. The response is identical to the GET response except that there is no response body.
If you encrypt an object by using server-side encryption with customer-provided encryption keys (SSE-C) when you store the object in Amazon S3, then when you retrieve the metadata from the object, you must use the following headers:
x-amz-server-side-encryption-customer-algorithm
x-amz-server-side-encryption-customer-key
x-amz-server-side-encryption-customer-key-MD5
For more information about SSE-C, see Server-Side Encryption (Using Customer-Provided Encryption Keys) .
Note
Encryption request headers, like x-amz-server-side-encryption , should not be sent for GET requests if your object uses server-side encryption with CMKs stored in AWS KMS (SSE-KMS) or server-side encryption with Amazon S3–managed encryption keys (SSE-S3). If your object does use these types of keys, you’ll get an HTTP 400 BadRequest error.
Request headers are limited to 8 KB in size. For more information, see Common Request Headers .
Consider the following when using request headers:
Consideration 1 – If both of the If-Match and If-Unmodified-Since headers are present in the request as follows:
If-Match condition evaluates to true , and;
If-Unmodified-Since condition evaluates to false ;
Then Amazon S3 returns 200 OK and the data requested.
Consideration 2 – If both of the If-None-Match and If-Modified-Since headers are present in the request as follows:
If-None-Match condition evaluates to false , and;
If-Modified-Since condition evaluates to true ;
Then Amazon S3 returns the 304 Not Modified response code.
For more information about conditional requests, see RFC 7232 .
Permissions
You need the s3:GetObject permission for this operation. For more information, see Specifying Permissions in a Policy . If the object you request does not exist, the error Amazon S3 returns depends on whether you also have the s3:ListBucket permission.
If you have the s3:ListBucket permission on the bucket, Amazon S3 returns an HTTP status code 404 ("no such key") error.
If you don’t have the s3:ListBucket permission, Amazon S3 returns an HTTP status code 403 ("access denied") error.

Response Structure
(dict) --
DeleteMarker (boolean) --
Specifies whether the object retrieved was (true) or was not (false) a Delete Marker. If false, this response header does not appear in the response.
AcceptRanges (string) --
Indicates that a range of bytes was specified.
Expiration (string) --
If the object expiration is configured (see PUT Bucket lifecycle), the response includes this header. It includes the expiry-date and rule-id key-value pairs providing object expiration information. The value of the rule-id is URL encoded.
Restore (string) --
If the object is an archived object (an object whose storage class is GLACIER), the response includes this header if either the archive restoration is in progress (see RestoreObject or an archive copy is already restored.
If an archive copy is already restored, the header value indicates when Amazon S3 is scheduled to delete the object copy. For example:
x-amz-restore: ongoing-request="false", expiry-date="Fri, 23 Dec 2012 00:00:00 GMT"
If the object restoration is in progress, the header returns the value ongoing-request="true" .

Size of the body in bytes.
ETag (string) --
An ETag is an opaque identifier assigned by a web server to a specific version of a resource found at a URL.
MissingMeta (integer) --
This is set to the number of metadata entries not returned in x-amz-meta headers. This can happen if you create metadata using an API like SOAP that supports more flexible metadata than the REST API. For example, using SOAP, you can create metadata whose values are not legal HTTP headers.
VersionId (string) --
Version of the object.
CacheControl (string) --
Specifies caching behavior along the request/reply chain.
ContentDisposition (string) --
Specifies presentational information for the object.

Expires (datetime) --
The date and time at which the object is no longer cacheable.
WebsiteRedirectLocation (string) --
If the bucket is configured as a website, redirects requests for this object to another object in the same bucket or to an external URL. Amazon S3 stores the value of this header in the object metadata.
ServerSideEncryption (string) --
If the object is stored using server-side encryption either with an AWS KMS customer master key (CMK) or an Amazon S3-managed encryption key, the response includes this header with the value of the server-side encryption algorithm used when storing this object in Amazon S3 (for example, AES256, aws:kms).

If present, specifies the ID of the AWS Key Management Service (AWS KMS) symmetric customer managed customer master key (CMK) that was used for the object.
StorageClass (string) --
Provides storage class information of the object. Amazon S3 returns this header for all objects except for S3 Standard storage class objects.
For more information, see Storage Classes .
RequestCharged (string) --
If present, indicates that the requester was successfully charged for the request.
ReplicationStatus (string) --
Amazon S3 can return this header if your request involves a bucket that is either a source or destination in a replication rule.
In replication, you have a source bucket on which you configure replication and destination bucket where Amazon S3 stores object replicas. When you request an object (GetObject ) or object metadata (HeadObject ) from these buckets, Amazon S3 will return the x-amz-replication-status header in the response as follows:
If requesting an object from the source bucket — Amazon S3 will return the x-amz-replication-status header if the object in your request is eligible for replication. For example, suppose that in your replication configuration, you specify object prefix TaxDocs requesting Amazon S3 to replicate objects with key prefix TaxDocs . Any objects you upload with this key name prefix, for example TaxDocs/document1.pdf , are eligible for replication. For any object request with this key name prefix, Amazon S3 will return the x-amz-replication-status header with value PENDING, COMPLETED or FAILED indicating object replication status.
If requesting an object from the destination bucket — Amazon S3 will return the x-amz-replication-status header with value REPLICA if the object in your request is a replica that Amazon S3 created.
For more information, see Replication .
PartsCount (integer) --
The count of parts this object has.
ObjectLockMode (string) --
The Object Lock mode, if any, that's in effect for this object. This header is only returned if the requester has the s3:GetObjectRetention permission. For more information about S3 Object Lock, see Object Lock .
ObjectLockRetainUntilDate (datetime) --
The date and time when the Object Lock retention period expires. This header is only returned if the requester has the s3:GetObjectRetention permission.
ObjectLockLegalHoldStatus (string) --
Specifies whether a legal hold is in effect for this object. This header is only returned if the requester has the s3:GetObjectLegalHold permission. This header is not returned if the specified version of this object has never had a legal hold applied. For more information about S3 Object Lock, see Object Lock .
{'Uploads': {'StorageClass': {'OUTPOSTS'}}}
This operation lists in-progress multipart uploads. An in-progress multipart upload is a multipart upload that has been initiated using the Initiate Multipart Upload request, but has not yet been completed or aborted.
This operation returns at most 1,000 multipart uploads in the response. 1,000 multipart uploads is the maximum number of uploads a response can include, which is also the default value. You can further limit the number of uploads in a response by specifying the max-uploads parameter in the response. If additional multipart uploads satisfy the list criteria, the response will contain an IsTruncated element with the value true. To list the additional multipart uploads, use the key-marker and upload-id-marker request parameters.
In the response, the uploads are sorted by key. If your application has initiated more than one multipart upload using the same object key, then uploads in the response are first sorted by key. Additionally, uploads are sorted in ascending order within each key by the upload initiation time.
For more information on multipart uploads, see Uploading Objects Using Multipart Upload .
For information on permissions required to use the multipart upload API, see Multipart Upload API and Permissions .
The following operations are related to ListMultipartUploads :

)
string
[REQUIRED]
The name of the bucket to which the multipart upload was initiated.
When using this API with an access point, you must direct requests to the access point hostname. The access point hostname takes the form AccessPointName -AccountId .s3-accesspoint.*Region* .amazonaws.com. When using this operation using an access point through the AWS SDKs, you provide the access point ARN in place of the bucket name. For more information about access point ARNs, see Using Access Points in the Amazon Simple Storage Service Developer Guide .
When using this API with Amazon S3 on Outposts, you must direct requests to the S3 on Outposts hostname. The S3 on Outposts hostname takes the form AccessPointName -AccountId .*outpostID* .s3-outposts.*Region* .amazonaws.com. When using this operation using S3 on Outposts through the AWS SDKs, you provide the Outposts bucket ARN in place of the bucket name. For more information about S3 on Outposts ARNs, see Using S3 on Outposts in the Amazon Simple Storage Service Developer Guide .
string
Character you use to group keys.
All keys that contain the same string between the prefix, if specified, and the first occurrence of the delimiter after the prefix are grouped under a single result element, CommonPrefixes . If you don't specify the prefix parameter, then the substring starts at the beginning of the key. The keys that are grouped under CommonPrefixes result element are not returned elsewhere in the response.
string
Requests Amazon S3 to encode the object keys in the response and specifies the encoding method to use. An object key may contain any Unicode character; however, XML 1.0 parser cannot parse some characters, such as characters with an ASCII value from 0 to 10. For characters that are not supported in XML 1.0, you can add this parameter to request that Amazon S3 encode the keys in the response.
string
Together with upload-id-marker, this parameter specifies the multipart upload after which listing should begin.
If upload-id-marker is not specified, only the keys lexicographically greater than the specified key-marker will be included in the list.
If upload-id-marker is specified, any multipart uploads for a key equal to the key-marker might also be included, provided those multipart uploads have upload IDs lexicographically greater than the specified upload-id-marker .
integer
Sets the maximum number of multipart uploads, from 1 to 1,000, to return in the response body. 1,000 is the maximum number of uploads that can be returned in a response.
string
Lists in-progress uploads only for those keys that begin with the specified prefix. You can use prefixes to separate a bucket into different grouping of keys. (You can think of using prefix to make groups in the same way you'd use a folder in a file system.)
string
Together with key-marker, specifies the multipart upload after which listing should begin. If key-marker is not specified, the upload-id-marker parameter is ignored. Otherwise, any multipart uploads for a key equal to the key-marker might be included in the list only if they have an upload ID lexicographically greater than the specified upload-id-marker .
string
The account id of the expected bucket owner. If the bucket is owned by a different account, the request will fail with an HTTP 403 (Access Denied) error.

Keys that begin with the indicated prefix.
Delimiter (string) --
Causes keys that contain the same string between the prefix and the first occurrence of the delimiter to be rolled up into a single result element in the CommonPrefixes collection. These rolled-up keys are not returned elsewhere in the response. Each rolled-up result counts as only one return against the MaxKeys value.
MaxKeys (integer) --
Sets the maximum number of keys returned in the response. By default the API returns up to 1,000 key names. The response might contain fewer keys but will never contain more.
CommonPrefixes (list) --
All of the keys rolled up into a common prefix count as a single return when calculating the number of returns.
A response can contain CommonPrefixes only if you specify a delimiter.
CommonPrefixes contains all (if there are any) keys between Prefix and the next occurrence of the string specified by a delimiter.
CommonPrefixes lists keys that act like subdirectories in the directory specified by Prefix .
For example, if the prefix is notes/ and the delimiter is a slash (/ ) as in notes/summer/july , the common prefix is notes/summer/ . All of the keys that roll up into a common prefix count as a single return when calculating the number of returns.
(dict) --
Container for all (if there are any) keys between Prefix and the next occurrence of the string specified by a delimiter. CommonPrefixes lists keys that act like subdirectories in the directory specified by Prefix. For example, if the prefix is notes/ and the delimiter is a slash (/) as in notes/summer/july, the common prefix is notes/summer/.
Prefix (string) --
Container for the specified common prefix.
EncodingType (string) --
Encoding type used by Amazon S3 to encode object key names in the XML response.
If you specify the encoding-type request parameter, Amazon S3 includes this element in the response, and returns encoded key name values in the following response elements:
Delimiter, Prefix, Key, and StartAfter .
KeyCount (integer) --
KeyCount is the number of keys returned with this request. KeyCount will always be less than equals to MaxKeys field. Say you ask for 50 keys, your result will include less than equals 50 keys
ContinuationToken (string) --
If ContinuationToken was sent with the request, it is included in the response.
NextContinuationToken (string) --
NextContinuationToken is sent when isTruncated is true, which means there are more keys in the bucket that can be listed. The next list requests to Amazon S3 can be continued with this NextContinuationToken . NextContinuationToken is obfuscated and is not a real key
StartAfter (string) --
If StartAfter was sent with the request, it is included in the response.
{'StorageClass': {'OUTPOSTS'}}
Lists the parts that have been uploaded for a specific multipart upload. This operation must include the upload ID, which you obtain by sending the initiate multipart upload request (see CreateMultipartUpload ). This request returns a maximum of 1,000 uploaded parts. The default number of parts returned is 1,000 parts. You can restrict the number of parts returned by specifying the max-parts request parameter. If your multipart upload consists of more than 1,000 parts, the response returns an IsTruncated field with the value of true, and a NextPartNumberMarker element. In subsequent ListParts requests you can include the part-number-marker query string parameter and set its value to the NextPartNumberMarker field value from the previous response.

{'ReplicationConfiguration': {'Rules': {'Destination': {'StorageClass': {'OUTPOSTS'}}}}}
Creates a replication configuration or replaces an existing one. For more information, see Replication in the Amazon S3 Developer Guide .
Note
To perform this operation, the user or role performing the operation must have the iam:PassRole permission.
Specify the replication configuration in the request body. In the replication configuration, you provide the name of the destination bucket where you want Amazon S3 to replicate objects, the IAM role that Amazon S3 can assume to replicate objects on your behalf, and other relevant information.
A replication configuration must include at least one rule, and can contain a maximum of 1,000. Each rule identifies a subset of objects to replicate by filtering the objects in the source bucket. To choose additional subsets of objects to replicate, add a rule for each subset. All rules must specify the same destination bucket.
To specify a subset of the objects in the source bucket to apply a replication rule to, add the Filter element as a child of the Rule element. You can filter objects based on an object key prefix, one or more object tags, or both. When you add the Filter element in the configuration, you must also add the following elements: DeleteMarkerReplication , Status , and Priority .
Note
The latest version of the replication configuration XML is V2. XML V2 replication configurations are those that contain the Filter element for rules, and rules that specify S3 Replication Time Control (S3 RTC). In XML V2 replication configurations, Amazon S3 doesn't replicate delete markers. Therefore, you must set the DeleteMarkerReplication element to Disabled . For backward compatibility, Amazon S3 continues to support the XML V1 replication configuration.
For information about enabling versioning on a bucket, see Using Versioning .
By default, a resource owner, in this case the AWS account that created the bucket, can perform this operation. The resource owner can also grant others permissions to perform the operation. For more information about permissions, see Specifying Permissions in a Policy and Managing Access Permissions to Your Amazon S3 Resources .
Handling Replication of Encrypted Objects
By default, Amazon S3 doesn't replicate objects that are stored at rest using server-side encryption with CMKs stored in AWS KMS. To replicate AWS KMS-encrypted objects, add the following: SourceSelectionCriteria , SseKmsEncryptedObjects , Status , EncryptionConfiguration , and ReplicaKmsKeyID . For information about replication configuration, see Replicating Objects Created with SSE Using CMKs stored in AWS KMS .

Specifies which Amazon S3 objects to replicate and where to store the replicas.
ID (string) --
A unique identifier for the rule. The maximum value is 255 characters.
Priority (integer) --
The priority associated with the rule. If you specify multiple rules in a replication configuration, Amazon S3 prioritizes the rules to prevent conflicts when filtering. If two or more rules identify the same object based on a specified filter, the rule with higher priority takes precedence. For example:
Same object quality prefix-based filter criteria if prefixes you specified in multiple rules overlap
Same object qualify tag-based filter criteria specified in multiple rules
For more information, see `Replication < https://docs.aws.amazon.com/AmazonS3/latest/dev/replication.html>`__ in the Amazon Simple Storage Service Developer Guide .

Account (string) --
Destination bucket owner account ID. In a cross-account scenario, if you direct Amazon S3 to change replica ownership to the AWS account that owns the destination bucket by specifying the AccessControlTranslation property, this is the account ID of the destination bucket owner. For more information, see Replication Additional Configuration: Changing the Replica Owner in the Amazon Simple Storage Service Developer Guide .
StorageClass (string) --
The storage class to use when replicating objects, such as S3 Standard or reduced redundancy. By default, Amazon S3 uses the storage class of the source object to create the object replica.
For valid values, see the StorageClass element of the PUT Bucket replication action in the Amazon Simple Storage Service API Reference .
AccessControlTranslation (dict) --
Specify this only in a cross-account scenario (where source and destination bucket owners are not the same), and you want to change replica ownership to the AWS account that owns the destination bucket. If this is not specified in the replication configuration, the replicas are owned by same AWS account that owns the source object.
Owner (string) -- [REQUIRED]
Specifies the replica ownership. For default and valid values, see PUT bucket replication in the Amazon Simple Storage Service API Reference .
EncryptionConfiguration (dict) --
A container that provides information about encryption. If SourceSelectionCriteria is specified, you must specify this element.
ReplicaKmsKeyID (string) --
Specifies the ID (Key ARN or Alias ARN) of the customer managed customer master key (CMK) stored in AWS Key Management Service (KMS) for the destination bucket. Amazon S3 uses this key to encrypt replica objects. Amazon S3 only supports symmetric customer managed CMKs. For more information, see Using Symmetric and Asymmetric Keys in the AWS Key Management Service Developer Guide .

EventThreshold (dict) -- [REQUIRED]
A container specifying the time threshold for emitting the s3:Replication:OperationMissedThreshold event.
Minutes (integer) --
Contains an integer specifying time in minutes.
Valid values: 15 minutes.
DeleteMarkerReplication (dict) --
Specifies whether Amazon S3 replicates the delete markers. If you specify a Filter , you must specify this element. However, in the latest version of replication configuration (when Filter is specified), Amazon S3 doesn't replicate delete markers. Therefore, the DeleteMarkerReplication element can contain only <Status>Disabled</Status>. For an example configuration, see Basic Rule Configuration .
Note
If you don't specify the Filter element, Amazon S3 assumes that the replication configuration is the earlier version, V1. In the earlier version, Amazon S3 handled replication of delete markers differently. For more information, see Backward Compatibility .
Status (string) --
Indicates whether to replicate delete markers.
Note
In the current implementation, Amazon S3 doesn't replicate the delete markers. The status must be Disabled .
string
string
The account id of the expected bucket owner. If the bucket is owned by a different account, the request will fail with an HTTP 403 (Access Denied) error.
None
{'StorageClass': {'OUTPOSTS'}}
Adds an object to a bucket. You must have WRITE permissions on a bucket to add an object to it.
Amazon S3 never adds partial objects; if you receive a success response, Amazon S3 added the entire object to the bucket.
Amazon S3 is a distributed system. If it receives multiple write requests for the same object simultaneously, it overwrites all but the last object written. Amazon S3 does not provide object locking; if you need this, make sure to build it into your application layer or use versioning instead.
To ensure that data is not corrupted traversing the network, use the Content-MD5 header. When you use this header, Amazon S3 checks the object against the provided MD5 value and, if they do not match, returns an error. Additionally, you can calculate the MD5 while putting an object to Amazon S3 and compare the returned ETag to the calculated MD5 value.
Note
The Content-MD5 header is required for any request to upload an object with a retention period configured using Amazon S3 Object Lock. For more information about Amazon S3 Object Lock, see Amazon S3 Object Lock Overview in the Amazon Simple Storage Service Developer Guide .
Server-side Encryption
You can optionally request server-side encryption. With server-side encryption, Amazon S3 encrypts your data as it writes it to disks in its data centers and decrypts the data when you access it. You have the option to provide your own encryption key or use AWS managed encryption keys. For more information, see Using Server-Side Encryption .
Access Control List (ACL)-Specific Request Headers
You can use headers to grant ACL- based permissions. By default, all objects are private. Only the owner has full access control. When adding a new object, you can grant permissions to individual AWS accounts or to predefined groups defined by Amazon S3. These permissions are then added to the ACL on the object. For more information, see Access Control List (ACL) Overview and Managing ACLs Using the REST API .
Storage Class Options
By default, Amazon S3 uses the STANDARD storage class to store newly created objects. The STANDARD storage class provides high durability and high availability. Depending on performance needs, you can specify a different storage class. For more information, see Storage Classes in the Amazon S3 Service Developer Guide .
Versioning
If you enable versioning for a bucket, Amazon S3 automatically generates a unique version ID for the object being stored. Amazon S3 returns this ID in the response. When you enable versioning for a bucket, if Amazon S3 receives multiple write requests for the same object simultaneously, it stores all of the objects.
For more information about versioning, see Adding Objects to Versioning Enabled Buckets . For information about returning the versioning state of a bucket, see GetBucketVersioning .

string
The server-side encryption algorithm used when storing this object in Amazon S3 (for example, AES256, aws:kms).
string
If you don't specify, S3 Standard is the default storage class. Amazon S3 supports other storage classes.
string
If the bucket is configured as a website, redirects requests for this object to another object in the same bucket or to an external URL. Amazon S3 stores the value of this header in the object metadata. For information about object metadata, see Object Key and Metadata .
In the following example, the request header sets the redirect to an object (anotherPage.html) in the same bucket:
x-amz-website-redirect-location: /anotherPage.html
In the following example, the request header sets the object redirect to another website:
x-amz-website-redirect-location: http://www.example.com/
For more information about website hosting in Amazon S3, see Hosting Websites on Amazon S3 and How to Configure Website Page Redirects .
string
Specifies the algorithm to use to when encrypting the object (for example, AES256).
bytes
Specifies the customer-provided encryption key for Amazon S3 to use in encrypting data. This value is used to store the object and then it is discarded; Amazon S3 does not store the encryption key. The key must be appropriate for use with the algorithm specified in the x-amz-server-side-encryption-customer-algorithm header.
string
Specifies the 128-bit MD5 digest of the encryption key according to RFC 1321. Amazon S3 uses this header for a message integrity check to ensure that the encryption key was transmitted without error.

{'RestoreRequest': {'OutputLocation': {'S3': {'StorageClass': {'OUTPOSTS'}}}}}
Restores an archived copy of an object back into Amazon S3
This action is not supported by Amazon S3 on Outposts.
This action performs the following types of requests:
select - Perform a select query on an archived object
restore an archive - Restore an archived object
To use this operation, you must have permissions to perform the s3:RestoreObject action. The bucket owner has this permission by default and can grant this permission to others. For more information about permissions, see Permissions Related to Bucket Subresource Operations and Managing Access Permissions to Your Amazon S3 Resources in the Amazon Simple Storage Service Developer Guide .
Querying Archives with Select Requests
You use a select type of request to perform SQL queries on archived objects. The archived objects that are being queried by the select request must be formatted as uncompressed comma-separated values (CSV) files. You can run queries and custom analytics on your archived data without having to restore your data to a hotter Amazon S3 tier. For an overview about select requests, see Querying Archived Objects in the Amazon Simple Storage Service Developer Guide .
When making a select request, do the following:
Define an output location for the select query's output. This must be an Amazon S3 bucket in the same AWS Region as the bucket that contains the archive object that is being queried. The AWS account that initiates the job must have permissions to write to the S3 bucket. You can specify the storage class and encryption for the output objects stored in the bucket. For more information about output, see Querying Archived Objects in the Amazon Simple Storage Service Developer Guide . For more information about the S3 structure in the request body, see the following:
Managing Access with ACLs in the Amazon Simple Storage Service Developer Guide
Protecting Data Using Server-Side Encryption in the Amazon Simple Storage Service Developer Guide
Define the SQL expression for the SELECT type of restoration for your query in the request body's SelectParameters structure. You can use expressions like the following examples.
The following expression returns all records from the specified object. SELECT * FROM Object
Assuming that you are not using any headers for data stored in the object, you can specify columns with positional headers. SELECT s._1, s._2 FROM Object s WHERE s._3 > 100
If you have headers and you set the fileHeaderInfo in the CSV structure in the request body to USE , you can specify headers in the query. (If you set the fileHeaderInfo field to IGNORE , the first row is skipped for the query.) You cannot mix ordinal positions with header column names. SELECT s.Id, s.FirstName, s.SSN FROM S3Object s
For more information about using SQL with S3 Glacier Select restore, see SQL Reference for Amazon S3 Select and S3 Glacier Select in the Amazon Simple Storage Service Developer Guide .
When making a select request, you can also do the following:
To expedite your queries, specify the Expedited tier. For more information about tiers, see "Restoring Archives," later in this topic.
Specify details about the data serialization format of both the input object that is being queried and the serialization of the CSV-encoded query results.
The following are additional important facts about the select feature:
The output results are new Amazon S3 objects. Unlike archive retrievals, they are stored until explicitly deleted-manually or through a lifecycle policy.
You can issue more than one select request on the same Amazon S3 object. Amazon S3 doesn't deduplicate requests, so avoid issuing duplicate requests.
Amazon S3 accepts a select request even if the object has already been restored. A select request doesn’t return error response 409 .
Restoring Archives
Objects in the GLACIER and DEEP_ARCHIVE storage classes are archived. To access an archived object, you must first initiate a restore request. This restores a temporary copy of the archived object. In a restore request, you specify the number of days that you want the restored copy to exist. After the specified period, Amazon S3 deletes the temporary copy but the object remains archived in the GLACIER or DEEP_ARCHIVE storage class that object was restored from.
To restore a specific object version, you can provide a version ID. If you don't provide a version ID, Amazon S3 restores the current version.
The time it takes restore jobs to finish depends on which storage class the object is being restored from and which data access tier you specify.
When restoring an archived object (or using a select request), you can specify one of the following data access tier options in the Tier element of the request body:
**Expedited ** - Expedited retrievals allow you to quickly access your data stored in the GLACIER storage class when occasional urgent requests for a subset of archives are required. For all but the largest archived objects (250 MB+), data accessed using Expedited retrievals are typically made available within 1–5 minutes. Provisioned capacity ensures that retrieval capacity for Expedited retrievals is available when you need it. Expedited retrievals and provisioned capacity are not available for the DEEP_ARCHIVE storage class.
**Standard ** - S3 Standard retrievals allow you to access any of your archived objects within several hours. This is the default option for the GLACIER and DEEP_ARCHIVE retrieval requests that do not specify the retrieval option. S3 Standard retrievals typically complete within 3-5 hours from the GLACIER storage class and typically complete within 12 hours from the DEEP_ARCHIVE storage class.
**Bulk ** - Bulk retrievals are Amazon S3 Glacier’s lowest-cost retrieval option, enabling you to retrieve large amounts, even petabytes, of data inexpensively in a day. Bulk retrievals typically complete within 5-12 hours from the GLACIER storage class and typically complete within 48 hours from the DEEP_ARCHIVE storage class.
For more information about archive retrieval options and provisioned capacity for Expedited data access, see Restoring Archived Objects in the Amazon Simple Storage Service Developer Guide .
You can use Amazon S3 restore speed upgrade to change the restore speed to a faster speed while it is in progress. You upgrade the speed of an in-progress restoration by issuing another restore request to the same object, setting a new Tier request element. When issuing a request to upgrade the restore tier, you must choose a tier that is faster than the tier that the in-progress restore is using. You must not change any other parameters, such as the Days request element. For more information, see Upgrading the Speed of an In-Progress Restore in the Amazon Simple Storage Service Developer Guide .
To get the status of object restoration, you can send a HEAD request. Operations return the x-amz-restore header, which provides information about the restoration status, in the response. You can use Amazon S3 event notifications to notify you when a restore is initiated or completed. For more information, see Configuring Amazon S3 Event Notifications in the Amazon Simple Storage Service Developer Guide .
After restoring an archived object, you can update the restoration period by reissuing the request with a new period. Amazon S3 updates the restoration period relative to the current time and charges only for the request-there are no data transfer charges. You cannot update the restoration period when Amazon S3 is actively processing your current restore request for the object.
If your bucket has a lifecycle configuration with a rule that includes an expiration action, the object expiration overrides the life span that you specify in a restore request. For example, if you restore an object copy for 10 days, but the object is scheduled to expire in 3 days, Amazon S3 deletes the object in 3 days. For more information about lifecycle configuration, see PutBucketLifecycleConfiguration and Object Lifecycle Management in Amazon Simple Storage Service Developer Guide .
Responses
A successful operation returns either the 200 OK or 202 Accepted status code.
If the object copy is not previously restored, then Amazon S3 returns 202 Accepted in the response.
If the object copy is previously restored, Amazon S3 returns 200 OK in the response.
Special Errors
Code: RestoreAlreadyInProgress
Cause: Object restore is already in progress. (This error does not apply to SELECT type requests.)
HTTP Status Code: 409 Conflict
SOAP Fault Code Prefix: Client
Code: GlacierExpeditedRetrievalNotAvailable
Cause: S3 Glacier expedited retrievals are currently not available. Try again later. (Returned if there is insufficient capacity to process the Expedited request. This error applies only to Expedited retrievals and not to S3 Standard or Bulk retrievals.)
HTTP Status Code: 503
SOAP Fault Code Prefix: N/A
