Performing VM Restore

In case of a disaster, you can restore an entire oVirt VM from a backup. Veeam Backup for OLVM and RHV allows you to restore one or more VMs at a time, to the original location or to a new location.

VM restore is supported only for backups stored in backup repositories, object storage repositories, Veeam Cloud Connect repositories and on the performance, capacity and archive tier of a scale-out backup repository (except for backups stored in the archive tier that consists of the Amazon S3 Glacier Instant Retrieval extent).

Note

You cannot restore VMs from backups stored in external repositories and on tapes. However, you can copy backups to a supported repository and then use them to restore VMs.

How VM Restore Works

During the VM restore process, the following steps are performed:

The Veeam Backup & Replication console sends the restore session configuration data to the backup appliance.

If multiple VMs are added to the restore session, these VMs are processed in parallel.

[This step applies only if you perform restore to the original location and if the source VM is still present in the location] The backup appliance powers off the source VM and removes it from the oVirt KVM environment.
The backup appliance launches a worker.
The worker connects to the Virtualization manager over REST API and creates a VM in the target location.
The worker creates empty virtual disks in the target location. The number of empty disks equals the number of disks attached to the source VM.
The worker connects to the backup repository and restores backed-up data to the empty disks.

If multiple disks are attached to the source VM, the worker restores these disks sequentially, one disk at a time.

The worker attaches the created disks with the restored data to the VM.
