What I did to get rid of my mess, was to containerize service after service using podman. I mount all volumes in a unified location and define all containers as quadlets (systemd services). My backup therefore consists of the base directory where all my container volumes live in subdirectories and the directory with the systemd units for the quadlets.
That way I was able to slowly unify my setup without risking to break all at once. Plus, I can easily replicate it on any server that has podman.
No, I keep that private to minimize the information I leak about what I host, sorry. (I also don’t do git-ops for my server; I back the mentioned directories up via kopia so in case of recovery I just restore the last working state of data+config. I don’t have much need to version the configs.)
