Restore entire host from PBS... I accidentally nuked my homelab

[ligistx]

Hi...

I am in a bit of a hard spot and before I get myself into a harder spot, I figure I should make some posts and make sure I move forward correctly.

Slight backstory, I attempted to move my proxmox host from a single disk to a RAID1 ZFS array, I attempted to do this via creating a node with the new boot media, migrate VM's over, move ZFS boot media to the homelab hardware... TLDR; this went sideways on me. I could potentially spend some time to get that fixed, but realistically, lets assume this is a no go.

I can somewhat easily get proxmox installed fresh once again, and all of my VM's were backed up (to my virtual truenas box...) via PBS. I have a backup config of truenas so I can download truenas, spin up a VM, and get truenas back up relatively quickly.

The next step is what I have never done, and want to make sure I fully understand before I go down this path... I will need to spin up a new PBS VM, point it to my NFS share with all the saved VM's on it, and.... then what? Will it automatically recognize there is backup data there? I have my backups encrypted, if that matters (I do have the password).

How do I go about installing PBS and getting it to recognize my backups so I can restore them? Hopefully the backups are not tied to the PBS client itself, that would be rather catastrophic.

No, there is no auto detection nor a datastore import function. You will have to edit your /etc/proxmox-backup/datastore.cfg and add a new datastore pointing to the mountpoint of your NFS share. But not sure how to handle the encryption. But as client-side encryption is used you probably need to import that encryption key on your PVE when adding a PBS storage there.

Thankfully I just finished getting the “failed” ssd back into the cluster and got everything migrated back… but I do need to figure this out for the future.

I will try and figure out how to load a backup from a different PBS host. If I can figure this out, this would be the way to go about this in the future I think.
