Attaching a Disk to an Existing VM for Azure

You can restore an Azure VM disk and attach it to an existing VM.

Considerations

You can perform attach disk restores from all types of backups (streaming backups, IntelliSnap backups, and IntelliSnap backup copies), with both managed and unmanaged disks (but not unmanaged disks from IntelliSnap backups).
You cannot perform attach disk restores from encrypted VM disks.
You cannot attach a disk to a VM if the target VM is configured with the managed storage account for boot diagnostics. Instead of using the managed storage account for boot diagnostics, use a custom storage account, and then attach the disk to the VM.
For Azure Classic, you cannot attach a VM disk to multiple VMs that are part of the same Cloud Service group.

From the Command Center navigation pane, go to Protect > Virtualization.

The Virtual machines page appears.
On the VM groups tab, in the row for the VM group that contains the disk, click the action button , and then click Restore.

The Select restore type page appears.
Select Attach disk to existing VM.

The Attach disk to existing VM page appears.
To select a specific MediaAgent and/or source for the restore, in the upper-right area of the page, click the Settings button .

By default, the Commvault software automatically selects the MediaAgent and source as follows:
- MediaAgent: The software uses the MediaAgent that performed the backup.
- Source: By default, the software searches for the requested data in the primary copy. If the data is not found in the primary copy, the software selects a secondary or auxiliary copy.
For more information, see MediaAgent and Copy Precedence Considerations for Virtualization Restores.
Select the disk to restore, and then click Restore.

The Restore options dialog box appears.

Note

The following steps are performed on the Other hypervisor tab, which appears only for admin users—not for end users.

For Destination hypervisor, select the hypervisor to restore the disk to.
For Access node, leave Automatic (the default value) selected, or select an access node or an access node group.

If you select Automatic, the Commvault software performs the restore using the most suitable access node from the destination hypervisor.

If you select an access node group, the Commvault software performs the restore operation using the most suitable access node that is available in the access node group.

For access node selection, the Commvault software checks for the same region. If no region match is found, then any of the available access nodes from the selected destination hypervisor or access node group is used.
For Destination VM, select the VM to restore the disk to.
For Disk name, you can enter a different name for the restored disk.

If you do not enter a new disk name, a unique disk name is created automatically including a time stamp.
For Storage Account, select the storage account to restore the disk to.

Note

The following steps are performed on the My hypervisor tab, which appears for both admin users and end users.

For Select destination VM, select the VM to restore the disk to.

Only VMs that you have permissions for are available to select.
For Disk name, you can enter a different name for the restored disk.

If you do not enter a new disk name, a unique disk name is created automatically including a time stamp.
To overwrite an existing disk that has the same name, move the Unconditionally overwrite if it already exists toggle key to the right.
Click Submit to start the restore job.
