I use TineMachine to three separate idéntica disks: one at home, another one of the office, and and a third one at my parents place 1000 km away. Pretty anythingproof. I also have three other disks with three identical copies of my old archived stuff, in the same locations. Also all code repos are online (svn, git and hg), and I have most non-code stuff on Dropbox too. Restored entire machine from TimeMachine once when I upgraded the laptop, ideal experience. I’m not happy that Covid made me have the office disks at home now too, but otherwise, I feel pretty safe.
