Yes, and Nix is another bag of worms. My suggestion is first try to backup your Docker compose file and the configuration files, you can define in .gitignore which files or dirs to ignore and not backup. You don’t need any automated installation for your server, as it is fairly standard but you can easily do that if you run it as a VM on top of Proxmox and just create a snapshot of your VM.
Not a huge games uplift though. Anyway, congrats mate. Hope you are happy with your new toys.
