Options class
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.

Properties
- atime → Atime?
-
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 originalAtime
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.final - bytesPerSecond → int?
-
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
).final - gid → Gid?
-
The group ID (GID) of the file's owners.
final
- hashCode → int
-
The hash code for this object.
no setterinherited
- logLevel → LogLevel?
-
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, andTRANSFER
publishes logs for every file or object that is transferred and integrity checked.final - mtime → Mtime?
-
A value that indicates the last time that a file was modified (that is, a
file was written to) before the PREPARING phase.
final
- overwriteMode → OverwriteMode?
-
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.final - posixPermissions → PosixPermissions?
-
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.
final
- preserveDeletedFiles → PreserveDeletedFiles?
-
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.
final
- preserveDevices → PreserveDevices?
-
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.
Default value: NONE.
final
- runtimeType → Type
-
A representation of the runtime type of the object.
no setterinherited
- taskQueueing → TaskQueueing?
-
A value that determines whether tasks should be queued before executing the
tasks. If set to
ENABLED
, the tasks will be queued. The default isENABLED
.final - transferMode → TransferMode?
-
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.
final
- uid → Uid?
-
The user ID (UID) of the file's owner.
final
- verifyMode → VerifyMode?
-
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
final
