Options

--task-arn (string)

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

--cli-input-json | --cli-input-yaml (string) Reads arguments from the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, those 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. This may not be specified along with --cli-input-yaml.

--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. Similarly, if provided yaml-input it will print a sample input YAML that can be used with --cli-input-yaml. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command. The generated JSON skeleton is not stable between versions of the AWS CLI and there are no backwards compatibility guarantees in the JSON skeleton generated.

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
  • table
  • yaml
  • yaml-stream

--query (string)

A JMESPath query to use in filtering the response data.

--profile (string)

Use a specific profile from your credential file.

--region (string)

The region to use. Overrides config/env settings.

--version (string)

Display the version of this tool.

--color (string)

Turn on/off color output.

  • on
  • off
  • auto

--no-sign-request (boolean)

Do not sign requests. Credentials will not be loaded if this argument is provided.

--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.

--cli-binary-format (string)

The formatting style to be used for binary blobs. The default format is base64. The base64 format expects binary blobs to be provided as a base64 encoded string. The raw-in-base64-out format preserves compatibility with AWS CLI V1 behavior and binary values must be passed literally. When providing contents from a file that map to a binary blob fileb:// will always be treated as binary and use the file contents directly regardless of the cli-binary-format setting. When using file:// the file contents will need to properly formatted for the configured cli-binary-format.

  • base64
  • raw-in-base64-out

--no-cli-pager (boolean)

Disable cli pager for output.

--cli-auto-prompt (boolean)

Automatically prompt for CLI input parameters.

--no-cli-auto-prompt (boolean)

Disable automatically prompt for CLI input parameters.

The ARN of the most recent task execution.

SourceLocationArn -> (string)

The ARN of your transfer’s source location.

DestinationLocationArn -> (string)

The ARN of your transfer’s destination location.

CloudWatchLogGroupArn -> (string)

The Amazon Resource Name (ARN) of an Amazon CloudWatch log group for monitoring your task.

The ARNs of the network interfaces that DataSync created for your destination location.

(string)

Options -> (structure)

The task’s settings. For example, what file metadata gets preserved, how data integrity gets verified at the end of your transfer, bandwidth limits, among other options.

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 exclude filters that define the files, objects, and folders in your source location that you don’t want DataSync to transfer. For more information and examples, see Specifying what DataSync transfers by using filters .

(structure)

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. 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

Schedule -> (structure)

The schedule for when you want your task to run. For more information, see Scheduling your task .

ScheduleExpression -> (string)

Specifies your task schedule by using a cron or rate expression.

Use cron expressions for task schedules that run on a specific time and day. For example, the following cron expression creates a task schedule that runs at 8 AM on the first Wednesday of every month:

cron(0 8 * * 3#1)

Use rate expressions for task schedules that run on a regular interval. For example, the following rate expression creates a task schedule that runs every 12 hours:

rate(12 hours)

For information about cron and rate expression syntax, see the ` Amazon EventBridge User Guide https://docs.aws.amazon.com/eventbridge/latest/userguide/eb-scheduled-rule-pattern.html`__ .

Status -> (string)

Specifies whether to enable or disable your task schedule. Your schedule is enabled by default, but there can be situations where you need to disable it. For example, you might need to pause a recurring transfer to fix an issue with your task or perform maintenance on your storage system.

DataSync might disable your schedule automatically if your task fails repeatedly with the same error. For more information, see TaskScheduleDetails .
