Can you please share your backup strategies for linux? I'm curious to know what tools you use and why?How do you automate/schedule backups? Which files/folders you back up? What is your prefered hardware/cloud storage and how do you manage storage space?
restic to a local server and to cloud storage. it varies by device, but usually just everything in /home/. The rest of the operating system should be reproducible, whether through images, ansible, nix, or guix, given the information in /home/.
scheduling is done through systemd, usually (or the non-systemd equivalent). I use BackBlaze now, but I switch around occasionally. restic has policy based snapshot removal, and a prune option.
