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

Attention-grabbing element: The folder that did not unmount (/Volumes/.timemachine/Synology._smb._tcp.native./3C582361-50A6-47F2-947C-86A99A2B1A66/time-machine on this instance) is all the time completely different on every attempt. And it’s all the time created on the time the backup try began. And it all the time accommodates just one empty folder referred to as time-machine:
drwxr-xr-x 3 root wheel 96B 5 Nov 10:30 3C582361-50A6-47F2-947C-86A99A2B1A66
What I attempted up to now:
- Run laborious disk assessments on the Synology NAS (all HDDs are advantageous)
- Disabled and enabled Time Machine
- Run Disk Utility – First Support on all disks
- Manually deleted all present folders in
/Volumes/.timemachine/Synology._smb._tcp.native./ - Informed Time Machine to take away the prevailing backup and begin from scratch
- Rebooted the Mac a few occasions
None of that made a distinction. Any concept the best way to repair this problem?
