I've looked around and have not been able to find anything regarding backup of the server configuration. Is there a recommended way to backup the VE server itself (not backups of the VMs running on the VE server)?
There is no real way to import backuped host configs. Best would be to boot from time to time into a tool like clonezilla and do a blocklevel backup of the complete boot/root drive. If something fails you could then boot again into clonezilla and restore the complete drive from a backup.
If you can't shutdown the server and manually boot into clonezilla that often you could also use something like rsync or the proxmox-backup-client to create a backup of the mountpoint "/etc/pve" where all the PVE config files are stored.
They are also working on host backup capabilities for PBS but that isn't ready yet.
I had done enough poking to understand that I could treat it like a standard Debian host and do backups that way. It is good to know everything is in /etc/pve. I'll do a little poking around in there and see if a simple backup of that folder is enough for my needs. I am mainly looking for backup details like UUIDs of windows VMs so that licenses are not deactivated. I would be okay with some manual setup to recover. The install seemed exceptionally simple and quick.
