I have two Macs with the new macOS 12.01 Monterey, and one of them just won’t back up to a Multi-User Time Machine on SCALE 22.02-RC1.2. I even upgraded to the latest nightly that has SAMBA 4.15.3 but no improvement.
I created a new Time Machine share (since I couldn’t get the old one to work), so I’m starting from scratch. Time machine starts up and copies files. It gets to about 15% or so of 1.7 GB when it stops.
It leaves behind a non-working sparse bundle (I have to delete the dataset to be able to try again; I also reboot the Mac just in case).
According to the logs:
Failed to set string value '2021-12-12-192453,3,7232489367,7233933312,780,0,0,0' for extended attribute 'com.apple.timemachine.private.directorycompletiondate' on '/Volumes/Backups of imac2/2021-12-12-185920.inprogress/iMac HD - Data/Users/robert/Pictures/Aperture Library.aplibrary/Masters/2011', error: 92 Illegal byte sequence
As a test, I created a new Time Machine share on another Mac and the whole disk backed up fine (also using SMB).
But, just in case, I also turned off Bit Defender, closed Safari and everything else, and erased the Spotlight index on the source drive.
Any ideas what else I could try? The second Mac backs up fine, same OS, just a lot less data. There is plenty of space on the target pool. I know Time Machine is temperamental, but when it works, it's so convenient.
