"Use backintime instead. Timeshift stays running in the background even if auto snapshots aren't enabled, and it mounts my removable drive under /run/timeshift even though it is already mounted under /media -- which seems unnecessary and risky. Also it can fill the disk and freeze the system as others have pointed out. Also (unlike backintime) has no interface for easily restoring individual files or directories, so if you want to do that, you have to manually copy them using cp (or nemo if you must). Also, compared to backintime, Timeshift is barely configurable."
