Restoring Full Virtual Machines for Azure

You can restore virtual machines to the original location or to a different location. By default, a virtual machine is restored to the original hypervisor, using the same proxy as the backup.

Considerations

• If a virtual machine is encrypted using Azure Key Vault:

  • Full VM restores are supported per source subscription. However, restores of encrypted VMs to a different subscription are not supported due to an Azure limitation with restoring Key Vault across subscriptions.

  • Restoring to a different region under the same subscription will create a new key vault automatically, and the restore job will complete successfully. For more information, see AZR0002: Out of place VM restore to different region might fail when source VM is encrypted.

  • Keys and secrets are not accessible to subscription users by default when the Key Vault itself is restored. The restore operation will add only the application's service principal in the Key Vault access control as an authorized user. If necessary, the subscription administrator can make changes to these permissions using the Azure portal.

  • Microsoft restrictions for virtual machines encrypted using Azure Key Vault also apply to encrypted Azure virtual machines in your Commcell environment for restoring your virtual machine and Key Vault. For more information, see Azure Key Vault.

  • For VMs encrypted with customer-managed encryption keys, full VM restores complete successfully; however, for full VM restores from streaming backups, the customer-managed encryption key settings or disk encryption sets (DES) are not applied to the destination VM. You must manually apply the DES settings to the destination VM. For more information, see Configuring Disk Encryption Sets on Destination VM.

• You can back up virtual machines configured with Azure unmanaged and managed disks. From these backups, you can restore full virtual machines and restore guest files and folders. Live browse and restore is not supported for VMs that are encrypted with either volume or disk encryption.

• Due to a Microsoft limitation, you cannot change the hostname of a restored virtual machine.

Procedure

1. From the navigation pane, click Solutions > Virtualization > Hypervisors.

   The Hypervisors page appears.

2. Click the name of the hypervisor that hosts the virtual machines.

   The hypervisor details page appears. The VM groups area displays summary information for any existing VM groups.

3. In the VM groups area, click Restore for the VM group that contains the virtual machine.

4. In the Select restore type page, select Full virtual machine to restore one or more full virtual machines.

5. In the Restore page, expand the tree on the left and select the objects to be restored on the right. Select an item or click on an entry in the Name column to browse within an item.

   In the top right corner of the page, a "Showing" message indicates what backup data is being displayed. You can click the down arrow beside this message and select any of the following options:

   • Show latest backups: Only display data for the most recent backups.

   • Show backups as of a specific date: Only display data up to the date you specify.

6. Click Restore.

7. In the Restore options dialog box, provide the requested information:

   • The Azure subscription list displays the hypervisor for the Azure subscription. Select the Azure subscription client for the restore operation. The subscription type of the virtualization client (Classic or Azure Resource Manager) must match the type of the client for the source VM.

   • Power ON Virtual Machine after Restore: To automatically start the virtual machine after the restore is complete, select this check box.

     Note the following:

     • The power state of the virtual machine does not affect subsequent backups.

     • If the virtual machine is powered on during the backup operation, by default, the VM is powered on after the restore completes (unless you clear this check box).

     • If you perform an out-of-place restore, by default, the VM is powered off after the restore completes (regardless of the value selected for this option).

   • To delete an existing virtual machine and replace it with the restored VM, select Overwrite VMs if they already exist.

   • If you are restoring multiple VMs, click the All VMs tab on the bottom left to specify configuration values for all VMs you are restoring, or the name of each VM to specify values individually. Specify the following values:

     • Optional: To change the names of destination VMs, select Enable edit destination VM name.

     • Optional: When restoring multiple VMs, select Prefix or Suffix and enter a string to be appended to the original display name to create new destination VM names.

     • Optional: To change the name of an individual VM, enter the new display name in the Change VM display name to box.

     • Azure Classic only: Enter a name in the Cloud service box to specify the Cloud Services group for the restored VM.

     • Azure Resource Manager only: Enter a name in the Resource group box to specify the Resource Group for the restored VM.

     • For Storage account, select the storage account for a virtual machine or disk.

       You can specify any storage account in the same region as the selected cloud service (Classic) or resource group (ARM).

     • For VM size, select a size specification for the restored virtual machine.

     • For Network interface, select a network connection for the restored VM, or leave the default value of Auto Select.

     • Azure Resource Manager only: If a public IP address is not required on restored VMs, clear the Create Public IP checkbox.

     • Azure Resource Manager only: For Security Group, specify a network security group for the restored VM or leave the default value of Auto Select.

8. Click Submit to run the restore job.
