Raw units can only be backed up in full

[inode64]

When you try to backup a virtual machine with a raw disk if an incremental, differential or auto backup has been configured and a previous backup already exists and then you perform an incremental backup that displays an error indicating that only a full backup can be performed

Version used 2.17

Expected behavior show an error indicating the need to only use a full backup with raw drives

Hypervisor information: kvm

can you show an example log? Based on the idea of the implementation if raw devices are included, it should create a full backup for this particular device.

[abbbi]

so i have a VM with one raw device and one regular, i do:

./virtnbdbackup -d vm4 -o /tmp/foo --raw -l full

this will backup both devices.

Now if i create inc backup:

[2024-11-28 16:59:31] WARNING root virtnbdbackup - main [main]:  Raw disks can't be included during incremental or differential backup.
[2024-11-28 16:59:31] WARNING root virtnbdbackup - main [main]:  Excluding raw disks.

and that, for me, that is the expected behavior.

It fails differently if -l auto is used. That is something i could look into.

the command I use

/usr/bin/virtnbdbackup -d win2k12r2 --nocolor --noprogress -q --raw --compress -l auto -o /mnt/backup/kvm/win2k12r2/2024-46

If I am using auto, the first backup is done correctly and in that virtual machine there is a raw drive

I have already seen in commit. I see it well, unless a backup is made of the units that are not raw and thus avoid the error
