I run PBS as a virtual machine on Proxmox, with a dedicated physical harddrive passed through to PBS for the data.

While this protects from software failures of my VMs, it does not protect from catastrophic hardware failure. In theory I should be able to take the dedicated harddrive out and put it in any other system running a fresh PBS, but I have not tested this.

I tried running the same PBS with an external NFS share, but had speed and stability issue, mainly due to the hardware of the NFS host. And I wasn’t aware of autofs at the time, so the NFS share stayed disconnected
