+1 for PBS and it's dedup capabilities. I run a remote sync with it to offsite, along with ZFS reps of the underlying datastores.
As for Proxmox itself, I haven't bothered with backing the nodes themselves up, it's so simple to set up and cluster that if it went down, it would be a good chance for a nuke and pave, and restore VMs.
That person went a little overboard imho. Would be interested if they ever tried a complete recovery on that setup.
They talked about a distributed file system on their home cluster, without naming ceph.
