preserveDevices

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.

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.
