Avoid backing only a specific partition/disk inside a VM

[froek]

I have 2 partitions, one is the standard root LVM, and the second I attached to the VM from the host, by using "qm set 102 -ide1 /dev/sdb1" as a raw.

I do want to backup the standard root, but not the second IDE.

As you can see below there are some problems:

1. snapshot mode won't work - this is because /dev/sdb1 on the second disk is a GPT
2. the system tries to back up my second disk and runs out of space

I don't care about #1 so much, because if I can remove /dev/sdb1 from the backup set, I'm sure it will go back to snapshotting like it used to before I attached the second disk. The reason #2 fails is quite simply I have no space. Which is why I do NOT want the second disc backed up..

So my question is, is there a way to selectively assign partitions inside a vm for backing up? If not, this sort of defeats the purpose of allowing a raw attachment to a VM via the host.

you can disable backups ('no backups') for individual disk, just see the "hardware" tab on the gui.
