Restore Backups From Another Cluster

[Grunt]

My cluster is all kinds of jacked up. I've got PBS running as a VM inside the cluster and have backed up all my VMs to external storage. If I were to nuke my existing cluster and rebuild it, how would I go about restoring the backed up VMs?

Hello,

your backed VMs are stored in /var/lib/vz/dump.
Copy them to your external storage before formatting and reinstalling your cluster.
Then after a clean install, copy them back to that directory.
You'll then be able to restore your PBS VM as well as other saved VMs.

Kind regards,

GD

Do you actually mean VZDump backups or that your PBS VM got its datastore on an external storage?

In the latter case you should backup your PBS VM via VZDump to be able to restore it on the new cluster.

This is a good time to move your PBS to a separate physical machine, you have kind of a chicken-and-egg issue with it being virtualized (you have to restore the PBS on a new install before anything else, and then you're generating 2x the disk I/O load restoring from disk on the same machine.)

Also a good time to put together / document your DR process and plan for the future.
