Implement norto proxmox by adding second node.

[Fabio]

I have a proxmox node with version 6.4-15 running vps. The system makes backups on tuxis PBS.
Now I would like to add to safeguard the continuity of the VPS. In order not to overturn the existing node, which works reasonably well, how do you recommend operating in order to add a new node?
Consider that everything runs behind a firewall and the nodes can only be reached via VPN, so they are not exposed to the internet.

First keep in mind that a cluster needs 3 different machines for quorum. With only 2 full PVE nodes you need a third machine as qdevice.

Yes I know. I wanted to use pbs as the third node.
