Re: [ovirt-users] Backup and Restore of VMs

Hello, Thank you for the script, yes, it is clearer now. However, there is a something I misunderstand, my raisoning may be stupid, just tell me. It is closely about the backup process, precisely when the disk is attached to the vm... At this moment, an extern process should do this step. If we consider using the dd command to have a byte-to-byte copy from the snapshot disk, why not directly attaching this cloned raw virtual disk to the new OVF cloned VM instead of creating a new provisonned disk? But you just might consider doing file copy during the backup process (rsnyc like) which implies to format the new created disk and many additionnal steps as creating Logical Volumes if needed, etc... Can anybody help me with understanding this step? Thank you.
