Restoring a vma.zst backup that had passthrough RAID volumes

Hello All

I managed to get hold of a HP Gen8 server so I recently started using proxmox for the first time. It's great!

I have two hardware raid's set up. The first is a mirror raid to host the OS, the second is a larger Raid5 to act as the data storage.

I wanted to experiment with the setup and set up file sharing for the family, so I set up Proxmox on the server and, wishing to have file sharing, I set up an OMV virtual machine. Reading that OMV/TrueNAS work best when they have access to hardware I passed through my servers raid 5 volume to that guest OS hosted on proxmox.

I wanted to get the backups set up correctly so set up another OMV (on an rpi5) with NFS, added this storage to proxmox and set up vz dumps to it. I got no errors and the backups worked as expected. Knowing that backups are only as good as the ability to restore them I thought I'd test before I got too far into my set up.

I wiped my server ('the failure') reinstalled proxmox and tried to restore the backups. At this point I got a little (all right, a lot!!) stumped as the backup tried to restore the drive the guest OS was on but also the data volume in the backup all to the 'OS' drive which of course is too small.

Is it possible via command line to ask proxmox to restore just one drive? Then passthrough the large RAID volume again, re-run the restore and this time choose the larger disk?

I did read this thread but i'm not clever enough to know if it fits what I'm trying to do
