atime

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

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 phase of the task execution). This option is recommended.

• NONE - Ignores 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.
