What do you mean by hybrid disk?

As long as you don't want to use your existing qcow2 disk for disk passthrough you can use that with an existing VM.

I mean
/root and separate partition with qcow2 (virtual)
/backup with passtrough disk
it is possible?

A disk passed through using "Passthrough Physical Disk to Virtual Machine(VM)" is still a virtual disk. Its not real physical/direct passthrough like a PCI passthrough of a HBA would do. So its just presented to your VM as a second virtual disk. You can of cause then edit your VMs fstab to mount that second disk to "/backup",so stuff stored to "/backup" will end up on your passthroughed disk.
