- True, you can't transfer the snapshots with a backup job.
But when the job starts on NAS A, a snapshot is automatically taken before transferring the data and released once complete. This is to ensure data consistency.
That's what I think OP was referring to.
The issue is because the destination NAS doesn't recognize the UID/GIDs used for file permissions.
Since 6.5.0, there were changes in the algorithm responsible for the AD SIDs to UID/GIDs mapping. If both NAS are integrated to AD, using "rid" instead of "tdb" (check smb.conf), then the mapping will be calculated consistently on both sides. Otherwise it won't.
