Overview

Note:

When making an API call, you may pass Options data as a hash:

{
  verify_mode: "POINT_IN_TIME_CONSISTENT", # accepts POINT_IN_TIME_CONSISTENT, ONLY_FILES_TRANSFERRED, NONE
  overwrite_mode: "ALWAYS", # accepts ALWAYS, NEVER
  atime: "NONE", # accepts NONE, BEST_EFFORT
  mtime: "NONE", # accepts NONE, PRESERVE
  uid: "NONE", # accepts NONE, INT_VALUE, NAME, BOTH
  gid: "NONE", # accepts NONE, INT_VALUE, NAME, BOTH
  preserve_deleted_files: "PRESERVE", # accepts PRESERVE, REMOVE
  preserve_devices: "NONE", # accepts NONE, PRESERVE
  posix_permissions: "NONE", # accepts NONE, PRESERVE
  bytes_per_second: 1,
  task_queueing: "ENABLED", # accepts ENABLED, DISABLED
  log_level: "OFF", # accepts OFF, BASIC, TRANSFER
  transfer_mode: "CHANGED", # accepts CHANGED, ALL
}

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.

Instance Attribute Details

#atimeString

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.

If Atime is set to BEST_EFFORT, Mtime must be set to PRESERVE.

If Atime is set to NONE, Mtime must also be NONE.

Returns:

  • (String)

#log_levelString

A value that determines the type of logs that DataSync publishes to a log stream in the Amazon CloudWatch log group that you provide.

BASIC publishes logs on errors for individual files transferred, and TRANSFER publishes logs for every file or object that is transferred and integrity checked.

#overwrite_modeString

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.

Returns:

  • (String)

#preserve_deleted_filesString

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.

  SENSITIVE = []
  include Aws::Structure
end

#preserve_devicesString

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.

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.

Returns:

  • (String)

#task_queueingString

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.

#transfer_modeString

A value that determines whether DataSync transfers only the data and metadata that differ between the source and the destination location, or whether DataSync transfers all the content from the source, without comparing to the destination location.

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 to existing content on the destination.

#verify_modeString

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.
