@b0rk Great question! I have routine of doing a full disk iso backup right after completing the setup of a new laptop. The code is safe in github. Documents are safe in Nextcloud. It's the laptop's dev setup and the OS that are fragile. I use Partition Magic for Linux, TrueImage for OSX, and Macrium Reflect for Windows. Step (1) make a backup (2) buy a 2nd drive, swap it in (3) do a trial restore (4) hack away knowing you have a solid safety net under you
