[ovirt-users] Backup

Hi, I have one question regarding the backup architecture for ovirt.... 1. How to take the backup of VM ?? 2. Is there any way we can schedule the backup of all VM's on another storage(Suppose we have two storage one for VM disks and another for VM backups) ?? 3. Is there any way to restore the backup (after point 2) ?? 4. How to take the ovirt-engine database backup and restore it....is there any automated way to do this or we need to manually take the backup as we take the backup of postgresql ?? Thanks, Punit
