Restoring backup from off-site PBS server.

[SamTzu]

I'm planning to test restoring backup from off-site PBS server. I realised that I don't have a clue how to do this.
We have a remote backup server but no obvious way to sync back an old backup.
(One VM only.)
Restoration from local PBS is simple but how does one do it if the host does not have access to the off-site PBS?

You want grant the local PVE or PBS the needed rights (ideally via a dedicated API token and/or user), restore/sync everything and afterwards revoke the access rights.

Like I said, "the host does not have access to the off-site PBS."
This is by design. If the host had access some1 might be able to destroy the off-site backups.
Off-Site PBS should be able to push back the synced backups.

That's not possible, PBS can only push to another PBS. So you would setup a local PBS and configure the remote to push it's backips to the local. It might he useful to use a dedicated namespace on the local PBS to have privilege seperation
