Hi, I have 2 NAS with active directory security, there is a a rsync backup job from nas A to nas B. Nas B file persission/owner are set as default but after the rsync backup there are messed. Af...
- 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.

Hi jak0lantash,
yes, all true.
NAS A and NAS B are in AD
NAS A is old and FW latest and NAS B is new and FW latest
smb.conf in NAS A has idmap config * : backend = tdb
smb.conf in NAS B has idmap config * : backend = rid
There is a method for change idmap to rid for NAS A? Even reconfiguring all samba access?
Thanks
