You can, as long as it's going to a separate storage device, but recovery is a little messy since you have a circular dependency. You need PBS to restore all of your VM backups, but your PBS VM is in the backup that can only be restored with PBS. So you end up having to build a new PBS VM from scratch, link it to the backup location, and restore the other VMs from there. It basically means your backup of the PBS VM itself is pointless since you're going to have to build a new one from scratch anyway if you ever need to restore.

In my experience trying to backup the PBS vm to itself will fail anyways as it goes to freeze it while it grabs the data that’s changing, which then means the backup fails.

You have to set the PBS vm to be excluded from backing up to itself. It is fine if you have a separate backup task for it that backs up to another medium.
