{'Options': {'TransferMode': 'CHANGED | ALL'}}
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.

[REQUIRED]
The Amazon Resource Name (ARN) of the source location for the task.
string
[REQUIRED]
The Amazon Resource Name (ARN) of an AWS storage resource's location.
string
The Amazon Resource Name (ARN) of the Amazon CloudWatch log group that is used to monitor and log events in the task.
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 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. For more information, see create-task
Default value: POINT_IN_TIME_CONSISTENT.
ONLY_FILES_TRANSFERRED (recommended): Perform verification only on files that were transferred.
POINT_IN_TIME_CONSISTENT: Scan the entire source and entire destination at the end of the transfer to verify that source and destination are fully synchronized. This option isn't supported when transferring to S3 Glacier or S3 Glacier Deep Archive storage classes.
NONE: No additional verification is done at the end of the transfer, but all data transmissions are integrity-checked with checksum verification during the transfer.
OverwriteMode (string) --
A value that determines whether files at the destination should be overwritten or preserved when copying files. If set to NEVER a destination file will not be replaced by a source file, even if the destination file differs from the source file. If you modify files in the destination and you sync the files, you can use this value to protect against overwriting those changes.
Some storage classes have specific behaviors that can affect your S3 storage cost. For detailed information, see using-storage-classes in the AWS DataSync User Guide .
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. This option can affect your storage cost. If your task deletes objects, you might incur minimum storage duration charges for certain storage classes. For detailed information, see using-storage-classes in the AWS DataSync User Guide .
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 ).
TaskQueueing (string) --
A value that determines whether tasks should be queued before executing the tasks. If set to ENABLED , the tasks will be queued. The default is ENABLED .
If you use the same agent to run multiple tasks, you can enable the tasks to run in series. For more information, see queue-task-execution .
LogLevel (string) --
A value that determines the type of logs that DataSync publishes to a log stream in the Amazon CloudWatch log group that you provide. For more information about providing a log group for DataSync, see CloudWatchLogGroupArn . If set to OFF , no logs are published. BASIC publishes logs on errors for individual files transferred, and TRANSFER publishes logs for every file or object that is transferred and integrity checked.
TransferMode (string) --
TransferMode has two values: CHANGED and ALL. CHANGED performs an "incremental" or "delta sync", it compares file modification time between source and destination to determine which files need to be transferred. ALL skips destination inventory and transfers all files discovered on the source.
list
A list of filter rules that determines which files to exclude from a task. The list should contain a single filter string that consists of the patterns to exclude. The patterns are delimited by "|" (that is, a pipe), for example, "/folder1|/folder2"
(dict) --
Specifies which files, folders and objects to include or exclude when transferring files from source to destination.
FilterType (string) --
The type of filter rule to apply. AWS DataSync only supports the SIMPLE_PATTERN rule type.

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 ).
TaskQueueing (string) --
A value that determines whether tasks should be queued before executing the tasks. If set to ENABLED , the tasks will be queued. The default is ENABLED .
If you use the same agent to run multiple tasks, you can enable the tasks to run in series. For more information, see queue-task-execution .
LogLevel (string) --
A value that determines the type of logs that DataSync publishes to a log stream in the Amazon CloudWatch log group that you provide. For more information about providing a log group for DataSync, see CloudWatchLogGroupArn . If set to OFF , no logs are published. BASIC publishes logs on errors for individual files transferred, and TRANSFER publishes logs for every file or object that is transferred and integrity checked.
TransferMode (string) --
TransferMode has two values: CHANGED and ALL. CHANGED performs an "incremental" or "delta sync", it compares file modification time between source and destination to determine which files need to be transferred. ALL skips destination inventory and transfers all files discovered on the source.
Excludes (list) --
A list of filter rules that determines which files to exclude from a task. The list should contain a single filter string that consists of the patterns to exclude. The patterns are delimited by "|" (that is, a pipe), for example: "/folder1|/folder2"
(dict) --
Specifies which files, folders and objects to include or exclude when transferring files from source to destination.
FilterType (string) --
The type of filter rule to apply. AWS DataSync only supports the SIMPLE_PATTERN rule type.
Value (string) --
A single filter string that consists of the patterns to include or exclude. The patterns are delimited by "|" (that is, a pipe), for example: /folder1|/folder2
Includes (list) --
A list of filter rules that determines which files to include when running a task. The list should contain a single filter string that consists of the patterns to include. The patterns are delimited by "|" (that is, a pipe), for example: "/folder1|/folder2"
(dict) --
Specifies which files, folders and objects to include or exclude when transferring files from source to destination.
FilterType (string) --
The type of filter rule to apply. AWS DataSync only supports the SIMPLE_PATTERN rule type.
Value (string) --
A single filter string that consists of the patterns to include or exclude. The patterns are delimited by "|" (that is, a pipe), for example: /folder1|/folder2
StartTime (datetime) --
The time that the task execution was started.
EstimatedFilesToTransfer (integer) --
The expected number of files that is to be transferred over the network. This value is calculated during the PREPARING phase, before the TRANSFERRING phase. This value is the expected number of files to be transferred. It's calculated based on comparing the content of the source and destination locations and finding the delta that needs to be transferred.
EstimatedBytesToTransfer (integer) --
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.
BytesWritten (integer) --
The number of logical bytes written to the destination AWS storage resource.
BytesTransferred (integer) --
The physical number of bytes transferred over the network.
Result (dict) --
The result of the task execution.

TransferStatus (string) --
The status of the TRANSFERRING Phase.
VerifyDuration (integer) --
The total time in milliseconds that AWS DataSync spent in the VERIFYING phase.
VerifyStatus (string) --
The status of the VERIFYING Phase.
ErrorCode (string) --
Errors that AWS DataSync encountered during execution of the task. You can use this error code to help troubleshoot issues.
ErrorDetail (string) --
Detailed description of an error that was encountered during the task execution. You can use this information to help troubleshoot issues.
{'OverrideOptions': {'TransferMode': 'CHANGED | ALL'}}
Starts a specific invocation of a task. A TaskExecution value represents an individual run of a task. Each task can have at most one TaskExecution at a time.
TaskExecution has the following transition phases: INITIALIZING | PREPARING | TRANSFERRING | VERIFYING | SUCCESS/FAILURE.
For detailed information, see the Task Execution section in the Components and Terminology topic in the AWS DataSync User Guide .

[REQUIRED]
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. For more information, see create-task
Default value: POINT_IN_TIME_CONSISTENT.
ONLY_FILES_TRANSFERRED (recommended): Perform verification only on files that were transferred.
POINT_IN_TIME_CONSISTENT: Scan the entire source and entire destination at the end of the transfer to verify that source and destination are fully synchronized. This option isn't supported when transferring to S3 Glacier or S3 Glacier Deep Archive storage classes.
NONE: No additional verification is done at the end of the transfer, but all data transmissions are integrity-checked with checksum verification during the transfer.
OverwriteMode (string) --
A value that determines whether files at the destination should be overwritten or preserved when copying files. If set to NEVER a destination file will not be replaced by a source file, even if the destination file differs from the source file. If you modify files in the destination and you sync the files, you can use this value to protect against overwriting those changes.
Some storage classes have specific behaviors that can affect your S3 storage cost. For detailed information, see using-storage-classes in the AWS DataSync User Guide .
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. This option can affect your storage cost. If your task deletes objects, you might incur minimum storage duration charges for certain storage classes. For detailed information, see using-storage-classes in the AWS DataSync User Guide .
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).
