Well - to be fair, if you “cook your system”, you have a boiled system. It would be haphazardous to rely on the system booting for restoring a backup. It could be an option, I guess, as long as the system still boots.

Having had to fix a friend’s installation because timeshift filled up the system drive, I would say one of the biggest problems of mint is that it comes with timeshift enabled by default (and with shitty settings). I recommend keeping manual backups, and not trying to restore a system, as opposed to setting it up from scratch.

I use [not arch, but] debian, btw - haven’t had the system break on me in > 10 years. At worst, some driver gets messed up temporarily, but nothing that ever rendered my system unusable.
