PVE 8.2.2 Node Backup/Restore

[BryanVeluwe]

Hi, I have been looking for a way to backup my PVE without backing up all of my VM's since I already have a way to back those up. I have tried to use the built in backup function but cannot seem to be able to backup and restore just the node, all I can restore is the VM's and when I exclude all the VM's it does not run the backup. I am looking for a way to backup and restore similar to how ESXE did it, without the use of a second server for PBS. Anything would be greatly appreciated!

Backup / restore scripts with fsarchiver

You didn't mention if you are using zfs boot/root, so I am assuming LVM+ext4 rootfs.

Veeam will restore the LVM structure, but NOT lvm-thin! It also needs to restore to same-sized disk (cannot migrate to smaller; restoring to larger is untested but should work, may need to resize partitions after)

fsarchiver is more flexible (can restore to smaller disk, can convert XFS to ext4 and vice versa) but is more hands-on (need to know what you're doing as a sysadmin) and you need to re-run the proxmox installer ISO first to recreate the LVM structure.

If you're using zfs boot/root, you can attach a mirror to the rpool and use the proxmox boot utility to fix EFI boot / grub.
