[ovirt-users] Howto Backup and Restore on new Server

Hello, i want to backup a view VMs, delete the old Server, install on same Hardware a new one and restore the VMs. I use oVirt as All-in-One. What is the best Way? Can i simply copy the full snapshot to an external usb-disk, or should i use a external backup domain for that.? And Restore simply copy the snapshot backup to the VM Domain or use the same backup domain to import the VMs? Thx
