I do have a password. Sudo is just setup not to ask for it.
On servers of course I use a password for sudo - but on a home machine there’s not much of a point I don’t think. It’s off when I’m not actively using it, and if some attacker or malware has access to my user they already have access to all my important files, or have physical access.
Oh yeah, I backup all configs 4*day. The good thing about torrenting is even if I had catastrophic loss, as long as I have the list of torrents it should repopulate (assuming someone’s seeding).
Of course I also want to self host my personal photos/videos, and I can’t afford to lose those. I’ll have to look into seeing if any solutions support local storage plus maybe object storage as a backup.
