I know about pbs, I even have an IP set aside for it :) I do have the built-in proxmox backup function take nightly snapshots or my important vms to my nas, but I don’t have anything really put together. Also, nothing for my nas itself. It is configured in a raid 5, but as we all know, raid is not backup :)

One day, after I am done with <insert reason here>, I will have a bad ass, well thought out backup solution.
