Time Machine Fail Due to a Snapshot of an External Disk Could Not Be Created
Updated to 12.5.1 yesterday. Now I'm getting an error that one of my external drives can't be backed up because a snapshot of that drive can't be created. TM was working perfectly up until the update. Just prior to the update I moved two folders from one external drive to the other external drive TM is complaining about. It was about 297 GB of data, with 296 of it in one folder.
Not sure if the movement of data and then a fairly quick start of installing of 12.5.1 created a problem or not. I've tried to do all the solutions I could find. Some of which are no longer valid under 12.5.1. But no success. Here is what I've tried:
- Find the snapshot via terminal and delete. Not successful as I really don't see one for my specific drive. I used another command to try to delete all snapshots but Terminal wasn't having it.
- Deleted the last backup in the TM drive.
- Rebooted the computer several times
- Eject and remounted the offending drive multiple times
- Turn off Automatic Updates, leave for for over an hour, then turn back on and initiate backup. Multiple times.
- Boot into Safe Mode and attempt to start backup
- Find the Backups DB on the TM drive. No longer in Finder from what I can tell - turned on hidden files
Short of reformatting my TM drive and starting over, I can't think of anything else to do. I've rarely had TM issues, but when I do it seems like I have to resort to the "nuclear option" of wiping the TM drive and starting over. I have over 5 TB of data and I'd rather not go through a multi-day process. I do have an online backup so I'm not worried about how long it takes to do the new initial backup, I just don't want to have to do that.
