I use NixOS so all my system configuration is already saved in my NixOS configs, which I save on GitHub. For dotfiles that aren't managed by NixOS I use syncthing to sync them between my devices, but no real backup cause I can just remake them if I need to, and things like my Neovim and VSCode configs are managed by my NixOS configs so they're backed up as well.
You can take this to the extreme too by erasing your root partition each boot: https://grahamc.com/blog/erase-your-darlings/
Using that method you isolate all important state on the system for backup with zfs send.
Yeah I have a full impermanence setup using tmpfs, which is really nice. I did it like on the NixOS wiki and it's been helpful for organizing my dotfiles and keeping track of all the random stuff that programs put everywhere.
I actually have all my stuff in a separate /stuff folder kinda by accident so my /home only has dotfiles and things like that.
