I take advantage of a Synology NAS to backup my household’s MacBooks. Two are nonetheless working positive, however one among them was unable to make a backup for a couple of week. As a result of the opposite two MacBooks are nonetheless positive I’m fairly certain that the difficulty 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 did not 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 attempt. 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 up to now:
- Run exhausting disk assessments on the Synology NAS (all HDDs are positive)
- Disabled and enabled Time Machine
- Run Disk Utility – First Assist on all disks
- Manually deleted all current 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 find out how to repair this concern?
