"Tried to run my first snapshot and it ran out of disk space very close to completion. After it errored out, the partial failed snapshot was not visible under timeshift but it didn't get deleted either. Uninstalling timeshift did not delete the failed snapshot files either, and as it had used up 100% of the disk space I couldn't even get online to search for a solution. I had to manually hunt down the timeshift files, change permissions since they were created with root ownership, and then delete them to get my system working again. Unpleasant waste of time. The failure modes need to be much more graceful than this or it'll remain a dangerous system toy not a real utility."
