I use a combination of a .dotfiles folder and syncthing. my .dotfiles folder has a script in it that symlinks the dotfiles and folders out to the right places, then installs any tools with asdf and the .tool-versions I save. usually gets any Linux setup up and running in a few seconds. I then have a workspace folder that stores all my code and projects. I syncthing that between my computer and a 3rd server computer as a backup that has weekly backups running. the 3 way sync makes it easy to not lose anything, or if one machine goes down when I need my most recent files. Since I use WSL on Windows, the same stuff works mostly the same. The script I have is tailored to my preferred distros. I have currently a fedora one, but I also have an Ubuntu and a Arch one for when I used those or need to get my stuff setup on them. I try to keep all of them updated. asdf really helps with tools.
