I exploit a Synology NAS to backup my household’s MacBooks. Two are nonetheless working superb, however one among them was unable to make a backup for a few week. As a result of the opposite two MacBooks are nonetheless superb I’m fairly certain that the problem just isn’t associated to the current MacOS replace nor to the current Synology firmware replace.
The log file has repeating sections like the next:

Fascinating element: The folder that didn’t unmount (/Volumes/.timemachine/Synology._smb._tcp.native./3C582361-50A6-47F2-947C-86A99A2B1A66/time-machine on this instance) is at all times totally different on every strive. And it’s at all times created on the time the backup try began. And it at all times accommodates just one empty folder known as time-machine:
drwxr-xr-x 3 root wheel 96B 5 Nov 10:30 3C582361-50A6-47F2-947C-86A99A2B1A66
What I attempted to date:
- Run arduous disk checks on the Synology NAS (all HDDs are superb)
- Disabled and enabled Time Machine
- Run Disk Utility – First Assist on all disks
- Manually deleted all present folders in
/Volumes/.timemachine/Synology._smb._tcp.native./ - Instructed Time Machine to take away the present backup and begin from scratch
- Rebooted the Mac a few instances
None of that made a distinction. Any thought tips on how to repair this situation?
