)

type SourceLocationArn:

string

param SourceLocationArn:

[REQUIRED]

The Amazon Resource Name (ARN) of the source location for the task.

type DestinationLocationArn:

string

param DestinationLocationArn:

[REQUIRED]

The Amazon Resource Name (ARN) of an Amazon Web Services storage resource's location.

type CloudWatchLogGroupArn:

string

param CloudWatchLogGroupArn:

The Amazon Resource Name (ARN) of the Amazon CloudWatch log group that is used to monitor and log events in the task.

type Name:

string

param Name:

The name of a task. This value is a text reference that is used to identify the task in the console.

type Options:

dict

param Options:

Specifies the configuration options for a task. Some options include preserving file or object metadata and verifying data integrity.

You can also override these options before starting an individual run of a task (also known as a task execution). For more information, see StartTaskExecution.

VerifyMode (string) --

Specifies how and when DataSync checks the integrity of your data during a transfer.

Default value: POINT_IN_TIME_CONSISTENT

ONLY_FILES_TRANSFERRED (recommended): DataSync calculates the checksum of transferred files and metadata at the source location. At the end of the transfer, DataSync then compares this checksum to the checksum calculated on those files at the destination.

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 scans the entire source and destination to verify that both locations are fully synchronized.

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 doesn't run additional verification at the end of the transfer. All data transmissions are still integrity-checked with checksum verification during the transfer.
OverwriteMode (string) --

Specifies whether data at the destination location should be overwritten or preserved. If set to NEVER, a destination file for example 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 Amazon S3 storage cost. For detailed information, see Considerations when working with Amazon S3 storage classes in DataSync.
Atime (string) --

Specifies whether to preserve metadata indicating the last time a 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 of the task execution).

Note

The behavior of Atime isn't fully standard across platforms, so 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) --

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

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) --

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

For more information, see Metadata copied by DataSync.

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) --

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

For more information, see Metadata copied by DataSync.

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) --

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.

Default value: PRESERVE

PRESERVE: Ignore such destination files (recommended).

REMOVE: Delete 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.

Default value: NONE

NONE: Ignore special devices (recommended).

PRESERVE: Preserve 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 Metadata copied by DataSync.

Default value: PRESERVE

PRESERVE: Preserve POSIX-style permissions (recommended).

NONE: Ignore permissions.

Note

DataSync can preserve extant permissions of a source location.
BytesPerSecond (integer) --

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).
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.

If you set LogLevel to OFF, no logs are published. BASIC publishes logs on errors for individual files transferred. TRANSFER publishes logs for every file or object that is transferred and integrity checked.
TransferMode (string) --

Determines whether DataSync transfers only the data and metadata that differ between the source and the destination location or transfers all the content from the source (without comparing what's in the destination).

CHANGED: DataSync copies only data or metadata that is new or different content from the source location to the destination location.

ALL: DataSync copies all source location content to the destination (without comparing what's in the destination).
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 how DataSync handles metadata.

Default value: OWNER_DACL

OWNER_DACL: 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 that ensures sufficient permissions to files, folders, and metadata, see user.
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 object tags are preserved when transferring between object storage systems. If you want your DataSync task to ignore object tags, specify the NONE value.

Default Value: PRESERVE

type Excludes:

list

param Excludes:

Specifies a list of filter rules that exclude specific data during your transfer. For more information and examples, see Filtering data transferred by DataSync.

(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. 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

type Schedule:

dict

param Schedule:

Specifies a schedule used to periodically transfer files from a source to a destination location. The schedule should be specified in UTC time. For more information, see Scheduling your task.

ScheduleExpression (string) -- [REQUIRED]

A cron expression that specifies when DataSync initiates a scheduled transfer from a source to a destination location.

type Tags:

list

param Tags:

Specifies the tags that you want to apply to the Amazon Resource Name (ARN) representing the task.

Tags are key-value pairs that help you manage, filter, and search for your DataSync resources.

(dict) --

  The Amazon Resource Name (ARN) of the source file system's location.
- DestinationLocationArn (string) --
  
  The Amazon Resource Name (ARN) of the Amazon Web Services storage resource's location.
- CloudWatchLogGroupArn (string) --
  
  The Amazon Resource Name (ARN) of the Amazon CloudWatch log group that was used to monitor and log events in the task.
  
  For more information on these groups, see Working with Log Groups and Log Streams in the Amazon CloudWatch User Guide.
- SourceNetworkInterfaceArns (list) --
  
  The Amazon Resource Names (ARNs) of the network interfaces created for your source location. For more information, see Network interface requirements.
  - (string) --
- DestinationNetworkInterfaceArns (list) --
  
  The Amazon Resource Names (ARNs) of the network interfaces created for your destination location. For more information, see Network interface requirements.
  - (string) --
- Options (dict) --
  
  The configuration options that control the behavior of the StartTaskExecution operation. Some options include preserving file or object metadata and verifying data integrity.
  
  You can override these options for each task execution. For more information, see StartTaskExecution.
  - VerifyMode (string) --
    
    Specifies how and when DataSync checks the integrity of your data during a transfer.
    
    Default value: POINT_IN_TIME_CONSISTENT
    
    ONLY_FILES_TRANSFERRED (recommended): DataSync calculates the checksum of transferred files and metadata at the source location. At the end of the transfer, DataSync then compares this checksum to the checksum calculated on those files at the destination.
    
    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 scans the entire source and destination to verify that both locations are fully synchronized.
    
    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 doesn't run additional verification at the end of the transfer. All data transmissions are still integrity-checked with checksum verification during the transfer.
  - OverwriteMode (string) --
    
    Specifies whether data at the destination location should be overwritten or preserved. If set to NEVER, a destination file for example 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 Amazon S3 storage cost. For detailed information, see Considerations when working with Amazon S3 storage classes in DataSync.
  - Atime (string) --
    
    Specifies whether to preserve metadata indicating the last time a 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 of the task execution).
    
    Note
    
    The behavior of Atime isn't fully standard across platforms, so 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) --
    
    Specifies whether to preserve metadata indicating the last time that a file was written to before the PREPARING phase of your task execution. This option is required when you need to run the a task more than once.
    
    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) --
    
    Specifies the POSIX user ID (UID) of the file's owner.
    
    For more information, see Metadata copied by DataSync.
    
    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) --
    
    Specifies the POSIX group ID (GID) of the file's owners.
    
    For more information, see Metadata copied by DataSync.
    
    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) --
    
    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.
    
    Default value: PRESERVE
    
    PRESERVE: Ignore such destination files (recommended).
    
    REMOVE: Delete 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.
    
    Default value: NONE
    
    NONE: Ignore special devices (recommended).
    
    PRESERVE: Preserve 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 Metadata copied by DataSync.
    
    Default value: PRESERVE
    
    PRESERVE: Preserve POSIX-style permissions (recommended).
    
    NONE: Ignore permissions.
    
    Note
    
    DataSync can preserve extant permissions of a source location.
  - BytesPerSecond (integer) --
    
    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).
  - 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.
    
    If you set LogLevel to OFF, no logs are published. BASIC publishes logs on errors for individual files transferred. TRANSFER publishes logs for every file or object that is transferred and integrity checked.
  - TransferMode (string) --
    
    Determines whether DataSync transfers only the data and metadata that differ between the source and the destination location or transfers all the content from the source (without comparing what's in the destination).
    
    CHANGED: DataSync copies only data or metadata that is new or different content from the source location to the destination location.
    
    ALL: DataSync copies all source location content to the destination (without comparing what's in the destination).
  - 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 how DataSync handles metadata.
    
    Default value: OWNER_DACL
    
    OWNER_DACL: 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 that ensures sufficient permissions to files, folders, and metadata, see user.
    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 object tags are preserved when transferring between object storage systems. If you want your DataSync task to ignore object tags, specify the NONE value.
    
    Default Value: PRESERVE
- Excludes (list) --
  
  A list of filter rules that exclude specific data during your transfer. For more information and examples, see Filtering data transferred by DataSync.
  - (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. 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 (dict) --
  
  The schedule used to periodically transfer files from a source to a destination location.
  - ScheduleExpression (string) --
    
    A cron expression that specifies when DataSync initiates a scheduled transfer from a source to a destination location.
- ErrorCode (string) --
  
  Errors that 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.
- CreationTime (datetime) --
  
  The time that the task was created.

        Specifies the ARN of the S3 bucket where DataSync uploads your report.
      - BucketAccessRoleArn (string) --
        
        Specifies the Amazon Resource Name (ARN) of the IAM policy that allows DataSync to upload a task report to your S3 bucket. For more information, see Allowing DataSync to upload a task report to an Amazon S3 bucket.
  - OutputType (string) --
    
    Specifies the type of task report that you want:
    - SUMMARY_ONLY: Provides necessary details about your task, including the number of files, objects, and directories transferred and transfer duration.
    - STANDARD: Provides complete details about your task, including a full list of files, objects, and directories that were transferred, skipped, verified, and more.
  - ReportLevel (string) --

Response Structure

(dict) --

DescribeTaskExecutionResponse
- 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 (dict) --
  
  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 of these options before starting your task.
  - VerifyMode (string) --
    
    Specifies how and when DataSync checks the integrity of your data during a transfer.
    
    Default value: POINT_IN_TIME_CONSISTENT
    
    ONLY_FILES_TRANSFERRED (recommended): DataSync calculates the checksum of transferred files and metadata at the source location. At the end of the transfer, DataSync then compares this checksum to the checksum calculated on those files at the destination.
    
    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 scans the entire source and destination to verify that both locations are fully synchronized.
    
    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 doesn't run additional verification at the end of the transfer. All data transmissions are still integrity-checked with checksum verification during the transfer.
  - OverwriteMode (string) --
    
    Specifies whether data at the destination location should be overwritten or preserved. If set to NEVER, a destination file for example 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 Amazon S3 storage cost. For detailed information, see Considerations when working with Amazon S3 storage classes in DataSync.
  - Atime (string) --
    
    Specifies whether to preserve metadata indicating the last time a 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 of the task execution).
    
    Note
    
    The behavior of Atime isn't fully standard across platforms, so 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) --
    
    Specifies whether to preserve metadata indicating the last time that a file was written to before the PREPARING phase of your task execution. This option is required when you need to run the a task more than once.
    
    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) --
    
    Specifies the POSIX user ID (UID) of the file's owner.
    
    For more information, see Metadata copied by DataSync.
    
    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) --
    
    Specifies the POSIX group ID (GID) of the file's owners.
    
    For more information, see Metadata copied by DataSync.
    
    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) --
    
    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.
    
    Default value: PRESERVE
    
    PRESERVE: Ignore such destination files (recommended).
    
    REMOVE: Delete 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.
    
    Default value: NONE
    
    NONE: Ignore special devices (recommended).
    
    PRESERVE: Preserve 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 Metadata copied by DataSync.
    
    Default value: PRESERVE
    
    PRESERVE: Preserve POSIX-style permissions (recommended).
    
    NONE: Ignore permissions.
    
    Note
    
    DataSync can preserve extant permissions of a source location.
  - BytesPerSecond (integer) --
    
    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).
  - 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.
    
    If you set LogLevel to OFF, no logs are published. BASIC publishes logs on errors for individual files transferred. TRANSFER publishes logs for every file or object that is transferred and integrity checked.
  - TransferMode (string) --
    
    Determines whether DataSync transfers only the data and metadata that differ between the source and the destination location or transfers all the content from the source (without comparing what's in the destination).
    
    CHANGED: DataSync copies only data or metadata that is new or different content from the source location to the destination location.
    
    ALL: DataSync copies all source location content to the destination (without comparing what's in the destination).
  - 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 how DataSync handles metadata.
    
    Default value: OWNER_DACL
    
    OWNER_DACL: 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 that ensures sufficient permissions to files, folders, and metadata, see user.
    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 object tags are preserved when transferring between object storage systems. If you want your DataSync task to ignore object tags, specify the NONE value.
    
    Default Value: PRESERVE
- Excludes (list) --
  
  A list of filter rules that exclude specific data during your transfer. For more information and examples, see Filtering data transferred by DataSync.

- StartTime (datetime) --
  
  The time when the task execution started.
- EstimatedFilesToTransfer (integer) --
  
  The expected number of files, objects, and directories that DataSync will transfer over the network.

- EstimatedBytesToTransfer (integer) --
  
  The estimated physical number of bytes that will transfer over the network.
- FilesTransferred (integer) --
  
  The actual number of files, objects, and directories that DataSync transferred over the network. This value is updated periodically during the task execution's TRANSFERRING phase 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 transferred or to monitor your task execution.
- BytesWritten (integer) --

)

type TaskArn:

string

param TaskArn:

[REQUIRED]

Specifies the Amazon Resource Name (ARN) of the task that you want to start.

type OverrideOptions:

dict

param OverrideOptions:

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 of these options before starting your task.

VerifyMode (string) --

Specifies how and when DataSync checks the integrity of your data during a transfer.

Default value: POINT_IN_TIME_CONSISTENT

ONLY_FILES_TRANSFERRED (recommended): DataSync calculates the checksum of transferred files and metadata at the source location. At the end of the transfer, DataSync then compares this checksum to the checksum calculated on those files at the destination.

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 scans the entire source and destination to verify that both locations are fully synchronized.

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 doesn't run additional verification at the end of the transfer. All data transmissions are still integrity-checked with checksum verification during the transfer.
OverwriteMode (string) --

Specifies whether data at the destination location should be overwritten or preserved. If set to NEVER, a destination file for example 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 Amazon S3 storage cost. For detailed information, see Considerations when working with Amazon S3 storage classes in DataSync.
Atime (string) --

Specifies whether to preserve metadata indicating the last time a 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 of the task execution).

Note

The behavior of Atime isn't fully standard across platforms, so 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) --

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

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) --

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

For more information, see Metadata copied by DataSync.

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) --

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

For more information, see Metadata copied by DataSync.

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) --

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.

Default value: PRESERVE

PRESERVE: Ignore such destination files (recommended).

REMOVE: Delete 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.

Default value: NONE

NONE: Ignore special devices (recommended).

PRESERVE: Preserve 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 Metadata copied by DataSync.

Default value: PRESERVE

PRESERVE: Preserve POSIX-style permissions (recommended).

NONE: Ignore permissions.

Note

DataSync can preserve extant permissions of a source location.
BytesPerSecond (integer) --

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).
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.

If you set LogLevel to OFF, no logs are published. BASIC publishes logs on errors for individual files transferred. TRANSFER publishes logs for every file or object that is transferred and integrity checked.
TransferMode (string) --

Determines whether DataSync transfers only the data and metadata that differ between the source and the destination location or transfers all the content from the source (without comparing what's in the destination).

CHANGED: DataSync copies only data or metadata that is new or different content from the source location to the destination location.

ALL: DataSync copies all source location content to the destination (without comparing what's in the destination).
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 how DataSync handles metadata.

Default value: OWNER_DACL

OWNER_DACL: 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 that ensures sufficient permissions to files, folders, and metadata, see user.
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.

type TaskArn:

string

param TaskArn:

[REQUIRED]

The Amazon Resource Name (ARN) of the resource name of the task to update.

type Options:

dict

param Options:

Each option has a default value. Unless you need to, you don't have to configure any of these options before starting your task.

VerifyMode (string) --

Specifies how and when DataSync checks the integrity of your data during a transfer.

Default value: POINT_IN_TIME_CONSISTENT

ONLY_FILES_TRANSFERRED (recommended): DataSync calculates the checksum of transferred files and metadata at the source location. At the end of the transfer, DataSync then compares this checksum to the checksum calculated on those files at the destination.

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 scans the entire source and destination to verify that both locations are fully synchronized.

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 doesn't run additional verification at the end of the transfer. All data transmissions are still integrity-checked with checksum verification during the transfer.
OverwriteMode (string) --

Specifies whether data at the destination location should be overwritten or preserved. If set to NEVER, a destination file for example 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 Amazon S3 storage cost. For detailed information, see Considerations when working with Amazon S3 storage classes in DataSync.
Atime (string) --

Specifies whether to preserve metadata indicating the last time a 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 of the task execution).

Note

The behavior of Atime isn't fully standard across platforms, so 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) --

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

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) --

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

For more information, see Metadata copied by DataSync.

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) --

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

For more information, see Metadata copied by DataSync.

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) --

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.

Default value: PRESERVE

PRESERVE: Ignore such destination files (recommended).

REMOVE: Delete 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.

Default value: NONE

NONE: Ignore special devices (recommended).

PRESERVE: Preserve 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 Metadata copied by DataSync.

Default value: PRESERVE

PRESERVE: Preserve POSIX-style permissions (recommended).

NONE: Ignore permissions.

Note

DataSync can preserve extant permissions of a source location.
BytesPerSecond (integer) --

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).
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.

If you set LogLevel to OFF, no logs are published. BASIC publishes logs on errors for individual files transferred. TRANSFER publishes logs for every file or object that is transferred and integrity checked.
TransferMode (string) --

Determines whether DataSync transfers only the data and metadata that differ between the source and the destination location or transfers all the content from the source (without comparing what's in the destination).

CHANGED: DataSync copies only data or metadata that is new or different content from the source location to the destination location.

ALL: DataSync copies all source location content to the destination (without comparing what's in the destination).
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 how DataSync handles metadata.

Default value: OWNER_DACL

OWNER_DACL: 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 that ensures sufficient permissions to files, folders, and metadata, see user.
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 object tags are preserved when transferring between object storage systems. If you want your DataSync task to ignore object tags, specify the NONE value.

Default Value: PRESERVE

type Excludes:

list

param Excludes:

Specifies a list of filter rules that exclude specific data during your transfer. For more information and examples, see Filtering data transferred by DataSync.

(dict) --

Specifies which files, folders, and objects to include or exclude when transferring files from source to destination.
