restore backup of disk, attached in passthrough mode to a vm. Proxmox 8

[jdaw]

I have windows VM, that I installed on a ssd, that is attached to a vm in passthrough mode. Proxmox 8 happily backs it up to the NAS, but when I try to restore backup, it says that it cannot restore it, and doesn't show the disk.

This is logical, I guess, as SSD is attached to a VM, but how I can restore backup then? Can I detach it/restore/reattach? If so, how? If not - how can I do that restore?

Thanks.

Did you ever manage to resolve this? (Trying to restore a Ubuntu VM where it's system drive was on a passthrough drive).

Did you ever figure this out?

My VM system was running Ubuntu. What I did was to install Ubuntu on a new drive, and attached a virtual backup disk to the same machine. Then I used rsync to copy everything from the backup disk to the new disk. It worked.
