RSYNC backup from nas OS6 to nas OS6 change file permission/owner
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.
After that the webgui of the shares became slow in refreshing and in systemd-journal.log I found many errors like these:
readynasd[3105]: Failed 'wbinfo --gid-info 32802': failed to call wbcGetgrgid: WBC_ERR_DOMAIN_NOT_FOUND
readynasd[3105]: Could not get info for gid 32802
Any ideas how to avoid this?
Thanks
- 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 crazy_toy
the option is not flaggable in the rsync job when is on the sender nas, if i made a rsync job on the destination nas the otion is flaggable.
But in this case I lost the automated snapshot before the job and used for rsync

Are both NAS in AD?

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
