Feature Request: advanced restore options in GUI

[fiona]

Hi,

3 years on and this is still an issue. Whats the rationale behind deleting mountpoints that aren't part of the backup anyway? I mean ok, the data isn't important enough to be backed up, that doesn't mean I want the data to be gone after a restore...

FYI, a patch for improving the container restore behavior was proposed: https://lore.proxmox.com/pve-devel/20250205143554.87844-1-f.ebner@proxmox.com/T/

So Just I understand correctly I can`t restore my 100Gb boot drive individually without restoring the full file server that has an 2nd drive of 8TB data?

you manually restore a vDisk :

Hi,

Can you tell me which way and how I need to add to proxmox-backup-client restore vm/104/2025-01- 05T23:00:03Z drive-scsi0.img.fidx vm-104-disk-1.raw --repository 192.168.88.11:bs1 so that the disk can be restored in VM 104? I use local-lvm LVM-Thin.

you can allocate a disk in LVM thin and then, when restoring, redirect the data there:

pvesm alloc local-lvm 104 vm-104-disk-1 1G
lvchange -ay /dev/pve/vm-104-disk-1
proxmox-backup-client restore vm/104/2025-01- 05T23:00:03Z drive-scsi0.img.fidx --repository 192.168.88.11:bs1 - > /dev/pve/vm-104-disk-1
qm set 104 --scsi0...

Depends on how you set up your mount points, but more than likely yes. Drives that aren't backed up are wiped.

I found that, as a workaround you can edit the config file and remove the mountpoint that you want to keep. When you then do the restore a new disk is created for that mountpoint.

After the backup is complete and before you restart the container/vm you can edit the config and tell it to use the old disk instead of the one that got newly created. Then delete the newly created disk and you are done.

for containers, the whole filesystem is backed up as a whole currently, so no this is not possible right now.

Just to clarify, this is only relevant for containers. For VMs, only volumes that are included in the backup are wiped. The others are already kept as unused.
