I have been using a sparse bundle on an external RAID for my Time Machine backup for macOS.
However, I have just noticed that it has not been backing up since a recent update to Ventura. I can't recall what the update was to be honest!
So I tried to recall how I did this initially a year or so ago, and it involved sudo tmutil setdestination/inheritbackup...not actually sure.
In any event, I now cannot get the original backup sparse bundle to be used by Time Machine. My most recent effort is:
sudo tmutil setdestination "/Volumes/macOS 12 Time Machine"
...where that is the mounted volume, but this results in:
/Volumes/macOS 12 Time Machine: APFS volumes must be empty before their first use with Time Machine. (error 45)
The backup destination could not be set.
Having tried with inheritbackup, I am told is has successfully inherited, but the drive does not appear as an option in System Settings.
