Your question is quite generic because it depends how you have configured
your PVE, what will be the storage backends etc.
I will assume that you have one PVE server with VMs stored in a local
storage like LVM or ZFS. You have a NAS as well where you store the backups
of these VMs (full backups).NAS is configured on PVE as a NFS target.
So if your PVE server dies, the only thing needed is to mount NAS as NFS
target on the new PVE server and just retore the backups there. That could
take some time depending on the size of VMs.
If you have a reliable redundant backing storage for PVE which hosts the
VM disks another option could work also:
As the safeness of the VM disks gets guaranteed by your backing storage
just backup the VM configurations.
If a PVE server fails (hardware failure, or other reasons) you may just
setup a new one,
setup the storage the same way you had on the old failed PVE and restore
the respective VM configs.
Now you can just start them, no waiting for restoring a full backup.
As said this works only if the backing storage is reliable and redundant
(i.e a good ceph setup).
And more important: full off-site backups (Tape or external reliable
storage) should be made nonetheless.
For the case when the Datacenter burns down, gets hit by an avalanche.
Disasters can and do happen.

Hi All!
Can someone please advise what is the best procedure in case of recovery
disaster?
My scenario is:
I have a PVE Server running a few machines, I also have a NAS with some
disks... I wanna point to that NAS the backup of these machines (in a way I
can recover them in another server in case of hardware failure).
I see on PVE the Backup service, I am not sure if I have to recover a
whole VM to another server that is the proper service, it looks too simple
(mostly snapshots).
My plan is have Proxmox as a main server for VMs so, I have to think about
"if my hardware fails", what can I do to move the machines to another
server...
Much appreciated,
Leonardo D.
