Recovering a datastore on a new server

Hello everyone,

I have a Proxmox server with several virtual machines, including a Proxmox Backup Server VM that uses a data store located on my NAS at home.
My question is: if I lose my Proxmox server for any reason, would I be able to reconnect the data store to another Proxmox Backup Server? Because it seems that when you add a datastore, it needs to be empty.

Thanks for your help
