Performing Disk Restore
In case a disaster strikes, you can restore corrupted virtual disks of an Azure VM from a cloud-native snapshot or image-level backup. Veeam Backup for Microsoft Azure allows you to restore virtual disks to the original location or to a new location.
How Disk Restore Works
To restore virtual disks from a cloud-native snapshot, Veeam Backup for Microsoft Azure uses native Microsoft Azure capabilities. To restore virtual disks from an image-level backup, Veeam Backup for Microsoft Azure performs the following steps:
- [This step applies only if you perform restore from an archived backup] Retrieves data from the archived restore point.
- [This step applies only if you perform restore to the original location] Creates a staging resource group where virtual disks of the restored Azure VM will be created, and assigns the Veeam backup appliance ID tag to the group. The tag value is the ID of Azure VM running the backup appliance.
- Creates empty virtual disks. The number of empty virtual disks equals the number of disks you want to restore.
- Launches a worker instance in the Azure region where the restored virtual disks will reside, and attaches the empty virtual disks to the worker instance.
- Restores backed-up data to the empty virtual disks on the worker instance.
- Detaches the virtual disks with the restored data from the worker instance.
- Deallocates the worker instance.
- [This step applies only if you perform restore to the original location] Removes the source virtual disks from the Microsoft Azure infrastructure.
- [This step applies only if you perform restore to the original location] Moves the virtual disks from the staging resource group to the original resource group.
- [This step applies only if you perform restore to the original location] Removes the staging resource group.
Veeam Backup for Microsoft Azure does not attach the restored virtual disks to any Azure VM — the disks are placed to the specified location as standalone virtual disks.
To restore a virtual disk from a backup that is stored in an archive repository, you must retrieve the archived data first. You can either retrieve the archived data manually before you begin the restore operation, or launch the data retrieval process right from the restore wizard. To learn how to retrieve data manually, see Retrieving Data From Archive.
