Stupid question maybe, but would your backups even be safe? Sure, it was mentioned that you had to enter your sudo password, but let’s say you did that because you are careless, “rm -rf” would wipe all connected and mounted drives as well, so your backups would be gone, wouldn’t they? Or does Timeshift mount and unmount on demand? If so, what would happen if you ran “rm -rf” while a backup is being saved?! It seems to me that a simple “make backups” isn’t enough here.

Afaik a one-time-purchase to get rid of the ads is planned.
