Okay, so somehow a computer I'm helping to manage has got a total of three
.inprogress backups on its Time Machine drive that it doesn't seem to be able to tidy up; it's creating new backups without any issue, it just gets stuck on the finishing stage, presumably trying to get rid of the in progress files.
On Lion or later I would just use
tmutil delete to get rid of this safely, however Snow Leopard doesn't have this.
I don't want to use the bypass utility with the
rm command as I believe that will destroy the contents of hard-linked folders, resulting in other backups becoming incomplete if they had links to the same folder(s).
Is it safe to delete a Time Machine backup using Snow Leopard's Finder, or is there some other alternative I could try? Will
tmutil's delete command run if I transfer
tmutil from a Mountain Lion machine? I know it won't be able to trigger backups etc. since
backupd won't support it, but can the delete command still work on Snow Leopard?
