string
[REQUIRED]
The subdirectory in the NFS file system that is used to read data from the NFS source location or write data to the NFS destination. The NFS path should be a path that's exported by the NFS server, or a subdirectory of that path. The path should be such that it can be mounted by other NFS clients in your network.
To see all the paths exported by your NFS server. run "showmount -e nfs-server-name " from an NFS client that has access to your server. You can specify any directory that appears in the results, and any subdirectory of that directory. Ensure that the NFS export is accessible without Kerberos authentication.
To transfer all the data in the folder you specified, DataSync needs to have permissions to read all the data. To ensure this, either configure the NFS export with no_root_squash, or ensure that the permissions for all of the files that you want DataSync allow read access for all users. Doing either enables the agent to read the files. For the agent to access directories, you must additionally enable all execute access.
For information about NFS export configuration, see "http://web.mit.edu/rhel-doc/5/RHEL-5-manual/Deployment_Guide-en-US/s1-nfs-server-config-exports.html" (18.7. The /etc/exports Configuration File).
string
[REQUIRED]
The name of the NFS server. This value is the IP address or Domain Name Service (DNS) name of the NFS server. An agent that is installed on-premises uses this host name to mount the NFS server in a network.
Note
This name must either be DNS-compliant or must be an IP version 4 (IPv4) address.
dict
[REQUIRED]
Contains a list of Amazon Resource Names (ARNs) of agents that are used to connect to an NFS server.
AgentArns (list) -- [REQUIRED]
ARNs)of the agents to use for an NFS location.
(string) --
dict
The NFS mount options that DataSync can use to mount your NFS share.
Version (string) --
The specific NFS version that you want DataSync to use to mount your NFS share. If you don't specify a version, DataSync defaults to AUTOMATIC . That is, DataSync automatically selects a version based on negotiation with the NFS server.
list
The key-value pair that represents the tag that you want to add to the location. The value can be an empty string. We recommend using tags to name your resources.
(dict) --
Represents a single entry in a list of AWS resource tags. TagListEntry returns an array that contains a list of tasks when the ListTagsForResource operation is called.
Key (string) -- [REQUIRED]

LocationArn (string) --
The Amazon Resource Name (ARN) of the source NFS file system location that is created.
{'Excludes': [{'FilterType': 'SIMPLE_PATTERN', 'Value': 'string'}]}
Creates a task. A task is a set of two locations (source and destination) and a set of Options that you use to control the behavior of a task. If you don't specify Options when you create a task, AWS DataSync populates them with service defaults.
When you create a task, it first enters the CREATING state. During CREATING AWS DataSync attempts to mount the on-premises Network File System (NFS) location. The task transitions to the AVAILABLE state without waiting for the AWS location to become mounted. If required, AWS DataSync mounts the AWS location before each task execution.
If an agent that is associated with a source (NFS) location goes offline, the task transitions to the UNAVAILABLE status. If the status of the task remains in the CREATING status for more than a few minutes, it means that your agent might be having trouble mounting the source NFS file system. Check the task's ErrorCode and ErrorDetail. Mount issues are often caused by either a misconfigured firewall or a mistyped NFS server host name.

string
The name of a task. This value is a text reference that is used to identify the task in the console.
dict
The set of configuration options that control the behavior of a single execution of the task that occurs when you call StartTaskExecution . You can configure these options to preserve metadata such as user ID (UID) and group ID (GID), file permissions, data integrity verification, and so on.
For each individual task execution, you can override these options by specifying the OverrideOptions before starting a the task execution. For more information, see the operation.
VerifyMode (string) --
A value that determines whether a data integrity verification should be performed at the end of a task execution after all data and metadata have been transferred.
Default value: POINT_IN_TIME_CONSISTENT.
POINT_IN_TIME_CONSISTENT: Perform verification (recommended).
NONE: Skip verification.
Atime (string) --
A file metadata value that shows the last time a file was accessed (that is, when the file was read or written to). If you set Atime to BEST_EFFORT, DataSync attempts to preserve the original Atime attribute on all source files (that is, the version before the PREPARING phase). However, Atime 's behavior is not fully standard across platforms, so AWS DataSync can only do this on a best-effort basis.
Default value: BEST_EFFORT.
BEST_EFFORT: Attempt to preserve the per-file Atime value (recommended).
NONE: Ignore Atime .
Note
If Atime is set to BEST_EFFORT, Mtime must be set to PRESERVE.
If Atime is set to NONE, Mtime must also be NONE.
Mtime (string) --
A value that indicates the last time that a file was modified (that is, a file was written to) before the PREPARING phase.
Default value: PRESERVE.
PRESERVE: Preserve original Mtime (recommended)

A value that determines whether AWS DataSync should preserve the metadata of block and character devices in the source file system, and recreate the files with that device name and metadata on the destination.
Note
AWS DataSync can't sync the actual contents of such devices, because they are nonterminal and don't return an end-of-file (EOF) marker.
Default value: NONE.
NONE: Ignore special devices (recommended).
PRESERVE: Preserve character and block device metadata. This option isn't currently supported for Amazon EFS.
PosixPermissions (string) --

The estimated physical number of bytes that is to be transferred over the network.
FilesTransferred (integer) --
The actual number of files that was transferred over the network. This value is calculated and updated on an ongoing basis during the TRANSFERRING phase. It's updated periodically when each file is read from the source and sent over the network.
If failures occur during a transfer, this value can be less than EstimatedFilesToTransfer . This value can also be greater than EstimatedFilesTransferred in some cases. This element is implementation-specific for some location types, so don't use it as an indicator for a correct file number or to monitor your task execution.

The Amazon Resource Name (ARN) of the task to start.
dict
Represents the options that are available to control the behavior of a StartTaskExecution operation. Behavior includes preserving metadata such as user ID (UID), group ID (GID), and file permissions, and also overwriting files in the destination, data integrity verification, and so on.
A task has a set of default options associated with it. If you don't specify an option in StartTaskExecution , the default value is used. You can override the defaults options on each task execution by specifying an overriding Options value to StartTaskExecution .
VerifyMode (string) --
A value that determines whether a data integrity verification should be performed at the end of a task execution after all data and metadata have been transferred.
Default value: POINT_IN_TIME_CONSISTENT.
POINT_IN_TIME_CONSISTENT: Perform verification (recommended).
NONE: Skip verification.
Atime (string) --
A file metadata value that shows the last time a file was accessed (that is, when the file was read or written to). If you set Atime to BEST_EFFORT, DataSync attempts to preserve the original Atime attribute on all source files (that is, the version before the PREPARING phase). However, Atime 's behavior is not fully standard across platforms, so AWS DataSync can only do this on a best-effort basis.
Default value: BEST_EFFORT.
BEST_EFFORT: Attempt to preserve the per-file Atime value (recommended).
NONE: Ignore Atime .
Note
If Atime is set to BEST_EFFORT, Mtime must be set to PRESERVE.
If Atime is set to NONE, Mtime must also be NONE.
Mtime (string) --
A value that indicates the last time that a file was modified (that is, a file was written to) before the PREPARING phase.
Default value: PRESERVE.
PRESERVE: Preserve original Mtime (recommended)
NONE: Ignore Mtime .
Note
If Mtime is set to PRESERVE, Atime must be set to BEST_EFFORT.
If Mtime is set to NONE, Atime must also be set to NONE.
Uid (string) --
The user ID (UID) of the file's owner.
Default value: INT_VALUE. This preserves the integer value of the ID.
INT_VALUE: Preserve the integer value of UID and group ID (GID) (recommended).
NONE: Ignore UID and GID.
Gid (string) --
The group ID (GID) of the file's owners.
Default value: INT_VALUE. This preserves the integer value of the ID.
INT_VALUE: Preserve the integer value of user ID (UID) and GID (recommended).
NONE: Ignore UID and GID.
PreserveDeletedFiles (string) --
A value that specifies whether files in the destination that don't exist in the source file system should be preserved.
Default value: PRESERVE.
PRESERVE: Ignore such destination files (recommended).
REMOVE: Delete destination files that aren’t present in the source.
PreserveDevices (string) --
A value that determines whether AWS DataSync should preserve the metadata of block and character devices in the source file system, and recreate the files with that device name and metadata on the destination.
Note
AWS DataSync can't sync the actual contents of such devices, because they are nonterminal and don't return an end-of-file (EOF) marker.
Default value: NONE.
NONE: Ignore special devices (recommended).
PRESERVE: Preserve character and block device metadata. This option isn't currently supported for Amazon EFS.
PosixPermissions (string) --
A value that determines which users or groups can access a file for a specific purpose such as reading, writing, or execution of the file.
Default value: PRESERVE.
PRESERVE: Preserve POSIX-style permissions (recommended).
NONE: Ignore permissions.
Note
AWS DataSync can preserve extant permissions of a source location.
BytesPerSecond (integer) --
A value that limits the bandwidth used by AWS DataSync. For example, if you want AWS DataSync to use a maximum of 1 MB, set this value to 1048576 (=1024*1024 ).
list
A filter that determines which files to include in the transfer during a task execution based on the specified pattern in the filter. When multiple include filters are set, they are interpreted as an OR.
(dict) --
A pattern that determines which files to include in the transfer or which files to exclude.
FilterType (string) --
Specifies the type of filter rule pattern to apply. DataSync only supports the SIMPLE_PATTERN rule type.
Value (string) --
A pattern that defines the filter. The filter might include or exclude files is a transfer.
