Options

--task-execution-arn (string)

Specifies the Amazon Resource Name (ARN) of the task execution that you want information about.

--cli-input-json (string) Performs service operation based on the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, the CLI values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally.

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

Global Options

--debug (boolean)

Turn on debug logging.

--endpoint-url (string)

Override command's default URL with the given URL.

--no-verify-ssl (boolean)

By default, the AWS CLI uses SSL when communicating with AWS services. For each SSL connection, the AWS CLI will verify SSL certificates. This option overrides the default behavior of verifying SSL certificates.

--no-paginate (boolean)

Disable automatic pagination. If automatic pagination is disabled, the AWS CLI will only make one call, for the first page of results.

--output (string)

The formatting style for command output.

  • json
  • text

--ca-bundle (string)

The CA certificate bundle to use when verifying SSL certificates. Overrides config/env settings.

--cli-read-timeout (int)

The maximum socket read time in seconds. If the value is set to 0, the socket read will be blocking and not timeout. The default value is 60 seconds.

--cli-connect-timeout (int)

The maximum socket connect time in seconds. If the value is set to 0, the socket connect will be blocking and not timeout. The default value is 60 seconds.

Output

TaskExecutionArn -> (string)

The ARN of the task execution that you wanted information about. TaskExecutionArn is hierarchical and includes TaskArn for the task that was executed.

For example, a TaskExecution value with the ARN arn:aws:datasync:us-east-1:111222333444:task/task-0208075f79cedf4a2/execution/exec-08ef1e88ec491019b executed the task with the ARN arn:aws:datasync:us-east-1:111222333444:task/task-0208075f79cedf4a2 .

Status -> (string)

The status of the task execution.

Options -> (structure)

Indicates how your transfer task is configured. These options include how DataSync handles files, objects, and their associated metadata during your transfer. You also can specify how to verify data integrity, set bandwidth limits for your task, among other options.

Each option has a default value. Unless you need to, you don't have to configure any option before calling StartTaskExecution .

You also can override your task options for each task execution. For example, you might want to adjust the LogLevel for an individual execution.

VerifyMode -> (string)

Specifies if and how DataSync checks the integrity of your data at the end of your transfer.

  • ONLY_FILES_TRANSFERRED (recommended) - DataSync calculates the checksum of transferred data (including metadata) at the source location. At the end of the transfer, DataSync then compares this checksum to the checksum calculated on that data at the destination.

Note

This is the default option for Enhanced mode tasks .

We recommend this option when transferring to S3 Glacier Flexible Retrieval or S3 Glacier Deep Archive storage classes. For more information, see Storage class considerations with Amazon S3 locations .

  • POINT_IN_TIME_CONSISTENT - At the end of the transfer, DataSync checks the entire source and destination to verify that both locations are fully synchronized.

Note

The is the default option for Basic mode tasks and isn't currently supported with Enhanced mode tasks.

If you use a manifest , DataSync only scans and verifies what's listed in the manifest. You can't use this option when transferring to S3 Glacier Flexible Retrieval or S3 Glacier Deep Archive storage classes. For more information, see Storage class considerations with Amazon S3 locations .

  • NONE - DataSync performs data integrity checks only during your transfer. Unlike other options, there's no additional verification at the end of your transfer.

OverwriteMode -> (string)

Specifies whether DataSync should modify or preserve data at the destination location.

  • ALWAYS (default) - DataSync modifies data in the destination location when source data (including metadata) has changed. If DataSync overwrites objects, you might incur additional charges for certain Amazon S3 storage classes (for example, for retrieval or early deletion). For more information, see Storage class considerations with Amazon S3 transfers .
  • NEVER - DataSync doesn't overwrite data in the destination location even if the source data has changed. You can use this option to protect against overwriting changes made to files or objects in the destination.

Atime -> (string)

Specifies whether to preserve metadata indicating the last time a file was read or written to.

Note

The behavior of Atime isn't fully standard across platforms, so DataSync can only do this on a best-effort basis.
  • BEST_EFFORT (default) - DataSync attempts to preserve the original Atime attribute on all source files (that is, the version before the PREPARING steps of the task execution). This option is recommended.
  • NONE - Ignores 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)

Specifies whether to preserve metadata indicating the last time that a file was written to before the PREPARING step of your task execution. This option is required when you need to run the a task more than once.

  • PRESERVE (default) - Preserves original Mtime , which is recommended.
  • NONE - Ignores 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)

Specifies the POSIX user ID (UID) of the file's owner.

  • INT_VALUE (default) - Preserves the integer value of UID and group ID (GID), which is recommended.
  • NONE - Ignores UID and GID.

For more information, see Metadata copied by DataSync .

Gid -> (string)

Specifies the POSIX group ID (GID) of the file's owners.

  • INT_VALUE (default) - Preserves the integer value of user ID (UID) and GID, which is recommended.
  • NONE - Ignores UID and GID.

For more information, see Understanding how DataSync handles file and object metadata .

PreserveDeletedFiles -> (string)

Specifies whether files in the destination location that don't exist in the source should be preserved. This option can affect your Amazon S3 storage cost. If your task deletes objects, you might incur minimum storage duration charges for certain storage classes. For detailed information, see Considerations when working with Amazon S3 storage classes in DataSync .

  • PRESERVE (default) - Ignores such destination files, which is recommended.
  • REMOVE - Deletes destination files that aren’t present in the source.

Note

If you set this parameter to REMOVE , you can't set TransferMode to ALL . When you transfer all data, DataSync doesn't scan your destination location and doesn't know what to delete.

PreserveDevices -> (string)

Specifies whether DataSync should preserve the metadata of block and character devices in the source location and recreate the files with that device name and metadata on the destination. DataSync copies only the name and metadata of such devices.

Note

DataSync can't copy the actual contents of these devices because they're nonterminal and don't return an end-of-file (EOF) marker.
  • NONE (default) - Ignores special devices (recommended).
  • PRESERVE - Preserves character and block device metadata. This option currently isn't supported for Amazon EFS.

PosixPermissions -> (string)

Specifies which users or groups can access a file for a specific purpose such as reading, writing, or execution of the file.

For more information, see Understanding how DataSync handles file and object metadata .

  • PRESERVE (default) - Preserves POSIX-style permissions, which is recommended.
  • NONE - Ignores POSIX-style permissions.

Note

DataSync can preserve extant permissions of a source location.

BytesPerSecond -> (long)

Limits the bandwidth used by a DataSync task. For example, if you want DataSync to use a maximum of 1 MB, set this value to 1048576 (=1024*1024 ).

Note

Not applicable to Enhanced mode tasks .

TaskQueueing -> (string)

Specifies whether your transfer tasks should be put into a queue during certain scenarios when running multiple tasks . This is ENABLED by default.

LogLevel -> (string)

Specifies the type of logs that DataSync publishes to a Amazon CloudWatch Logs log group. To specify the log group, see CloudWatchLogGroupArn .

  • BASIC - Publishes logs with only basic information (such as transfer errors).
  • TRANSFER - Publishes logs for all files or objects that your DataSync task transfers and performs data-integrity checks on.
  • OFF - No logs are published.

TransferMode -> (string)

Specifies whether DataSync transfers only the data (including metadata) that differs between locations following an initial copy or transfers all data every time you run the task. If you're planning on recurring transfers, you might only want to transfer what's changed since your previous task execution.

  • CHANGED (default) - After your initial full transfer, DataSync copies only the data and metadata that differs between the source and destination location.
  • ALL - DataSync copies everything in the source to the destination without comparing differences between the locations.

SecurityDescriptorCopyFlags -> (string)

Specifies which components of the SMB security descriptor are copied from source to destination objects.

This value is only used for transfers between SMB and Amazon FSx for Windows File Server locations or between two FSx for Windows File Server locations. For more information, see Understanding how DataSync handles file and object metadata .

  • OWNER_DACL (default) - For each copied object, DataSync copies the following metadata:
    • The object owner.
    • NTFS discretionary access control lists (DACLs), which determine whether to grant access to an object. DataSync won't copy NTFS system access control lists (SACLs) with this option.
  • OWNER_DACL_SACL - For each copied object, DataSync copies the following metadata:
    • The object owner.
    • NTFS discretionary access control lists (DACLs), which determine whether to grant access to an object.
    • SACLs, which are used by administrators to log attempts to access a secured object. Copying SACLs requires granting additional permissions to the Windows user that DataSync uses to access your SMB location. For information about choosing a user with the right permissions, see required permissions for SMB , FSx for Windows File Server , or FSx for ONTAP (depending on the type of location in your transfer).
  • NONE - None of the SMB security descriptor components are copied. Destination objects are owned by the user that was provided for accessing the destination location. DACLs and SACLs are set based on the destination server’s configuration.

ObjectTags -> (string)

Specifies whether you want DataSync to PRESERVE object tags (default behavior) when transferring between object storage systems. If you want your DataSync task to ignore object tags, specify the NONE value.

Excludes -> (list)

The time when the task execution started.

EstimatedFilesToTransfer -> (long)

The number of files, objects, and directories that DataSync expects to transfer over the network. This value is calculated during the task execution's PREPARING step before the TRANSFERRING step.

How this gets calculated depends primarily on your task’s transfer mode configuration:

  • If TranserMode is set to CHANGED - The calculation is based on comparing the content of the source and destination locations and determining the difference that needs to be transferred. The difference can include:
    • Anything that's added or modified at the source location.
    • Anything that's in both locations and modified at the destination after an initial transfer (unless OverwriteMode is set to NEVER ).
    • (Basic task mode only) The number of items that DataSync expects to delete (if PreserveDeletedFiles is set to REMOVE ).
  • If TranserMode is set to ALL - The calculation is based only on the items that DataSync finds at the source location.

EstimatedBytesToTransfer -> (long)

The number of logical bytes that DataSync expects to write to the destination location.

FilesTransferred -> (long)

The number of files, objects, and directories that DataSync actually transfers over the network. This value is updated periodically during the task execution's TRANSFERRING step when something is read from the source and sent over the network.

If DataSync fails to transfer something, this value can be less than EstimatedFilesToTransfer . In some cases, this value can also be greater than EstimatedFilesToTransfer . This element is implementation-specific for some location types, so don't use it as an exact indication of what's transferring or to monitor your task execution.

BytesWritten -> (long)

The number of logical bytes that DataSync actually writes to the destination location.

BytesTransferred -> (long)

The number of bytes that DataSync sends to the network before compression (if compression is possible). For the number of bytes transferred over the network, see BytesCompressed .

BytesCompressed -> (long)

The number of physical bytes that DataSync transfers over the network after compression (if compression is possible). This number is typically less than BytesTransferred unless the data isn't compressible.
