<br>
Could you please clarify, what would be the process of making backup of a running VM to an existing backup storage domain?<br>
<br>
I’m asking because it looks like the process is going to be quite the same:<br>
1. Clone VM from a snapshot<br>
2. Move the cloned VM to a backup storage domain<br>
<br>
An ability of choosing destination storage for cloned VMs would increase backup efficiency. On the other hand, an ability of exporting VM from a snapshot would increase the efficiency in the same way even without creating new entity.<br>
<br>
Indeed, Backup SDs would increase efficiency of disaster recovery. But the same would be achieved by converting Export SDs to Data SDs using a small CLI utility.<br>
