Can we choose if we want to take snapshot of specific volume from vm
snapshot? This helps if VM (owner VM of VM snapshot) has multiple volumes along
with ROOT volume and the specified VM snapshot image represents chains of
snapshot images of each volume of the VM.
Probably we should add volumeId parameter to this to identify the volume
that needs to be backed up?
