If a production VM has failed and you need to recover it from the backup, you can use one of the two options that Veeam Backup & Replication offers:
- Instant VM Recovery*, which uses the vPower technology to start a VM directly from a compressed and deduplicated backup file. Instant VM Recovery creates a 'temporary spare' of the original VM and provides the minimum restore time possible (several seconds to several minutes).
- Full VM recovery, which actually recovers a full VM from the backup file and registers it on the target host. Though full VM recovery takes more time than Instant VM Recovery as you have to extract the VM image to the production storage, it actually recovers a failed VM on the production storage and provides full disk I/O performance.
You can restore a single VM or a multiple VMs at once, both to the original location or to a new location. VM(s) can be recovered to the latest state or any valid point in time.
When Veeam Backup & Replication creates a backup of a VM, it additionally stores information about the initial VM location to the backup file. As all initial VM settings are available, restore of a VM to the original location is extremely fast: you can do it basically in one click. Restore to the original location mitigates the risk of operator's errors: you do not have to provide any VM data during the restore process, so the chance to specify wrong settings is minimal.
* To learn about the Instant VM Recovery scenario, see Veeam Backup & Replication User Guide.
- You can restore a VM from any backup that has been successfully run at least once. Open the Backup & Replication view, select the Backups node in the inventory pane. Then expand the backup job and verify that there is at least one restore point available for the VM.
When you restore a VM to the original location, Veeam Backup & Replication automatically deletes the initial VM. For safety's sake, make sure that you use a non-production VM for this exercise.
To restore a full VM to its original location, perform the following steps:
- Open the Backup & Replication view.
- Select the Backups > Disk node in the inventory pane. Expand the backup job in the working area, right-click the necessary VM in the corresponding backup job and select Restore entire VM.
- At the Virtual Machines step of the wizard, select the VM in the list, click Point on the right and choose the necessary restore point. If you select an incremental restore point, Veeam Backup & Replication will automatically restore data blocks from the full backup file and the chain of incremental backup files.
- At the Restore mode step of the wizard, select Restore to the original location.
- Select Quick rollback. Veeam Backup & Replication will perform incremental VM restore — retrieve from the backup file only those data blocks that have changes since the selected restore point was created and write these data blocks to the source volume. This option lets you significantly speed up the restore process.
- At the Reason step of the wizard, specify the reason for restoring the VM.
- At the last step of the wizard, select the Power on VM after restoring check box. Then click Finish.
Open the Hyper-V Manager and make sure that the restored VM is running on on the original host.
