That is a good question. We recently introduced a new feature called "backup storage domain" which you can mark the storage domain as backup storage domain. That can guarantee that no VMs will run with disks/leases reside on the storage domain. The feature should already exist in oVirt 4.2 (despite a bug that should be handled with this patch https://gerrit.ovirt.org/#/c/81290/) You can find more information on this here: https://github.com/shubham0d/ovirt-site/blob/41dcb0f1791d90d1ae0ac43cd34a399cfedf54d8/source/develop/release-management/features/storage/backup-storage-domain.html.md Basically the OVF that is being saved in the export domain should be similar to the same one that is being saved in the OVF_STORE disk in the storage domain. If the user manages replication on that storage domain it can be re-used for backup purposes by importing it to a setup. Actually it is much more efficient to use a data storage domain than to use the copy operation to/from the export storage domain. > > Nir _______________________________________________ Users mailing list Users@ovirt.org http://lists.ovirt.org/mailman/listinfo/users
