IntelliSnap Support for Virtualization

The following hypervisors support IntelliSnap backups and restores:

Amazon

You can configure an Amazon hypervisor to perform IntelliSnap backups. From the snap or backup copy, you can restore full instances, restore a volume and attach it to an existing instance, and restore guest files and folders.

Microsoft Azure

  • You can configure an Azure hypervisor to perform IntelliSnap backups. From the snap or backup copy, you can restore full virtual machines, restore a disk and attach it to an existing virtual machine, and restore guest files and folders.

    This feature is only available for Azure hypervisors created in Service Pack 13 or later.

  • You can backup virtual machines configured with Azure unmanaged and managed disks. From the snap or backup copy of these disks, you can restore full virtual machines and restore guest files and folders.

Microsoft Azure Stack

  • You can configure an Azure Stack hypervisor to perform IntelliSnap backups. From the snap or backup copy, you can restore full virtual machines and restore guest files and folders.

    This feature is only available for Azure Stack hypervisors created in Service Pack 13 or later.

  • You can backup virtual machines configured with Azure Stack unmanaged and managed disks. From the snap or backup copy of these disks, you can restore full virtual machines and restore guest files and folders.

    When executing a restore of a full VM (configured with Azure Stack managed disks), because of a Microsoft Azure limitation, you can only restore the VM to the same Azure Region where the snapshot was created (the source of the snap copy used to restore the VM).

Microsoft Hyper-V

You can configure a Hyper-V hypervisor to perform IntelliSnap backups. From the snap copy, you can restore full VMs and restore guest files and folders.

VMware

You can configure a VMware hypervisor to perform IntelliSnap backups. From the snap copy, you can restore full VMs, restore a disk and attach it to an existing VM, and restore guest files and folders.

Configuration

To enable IntelliSnap support, perform the following tasks:

  1. Configure storage:
  2. Add the hypervisor:
  3. Create a server plan, see Create a server plan.
  4. Associate the plan with a VM group.

    Note: For Amazon, Azure and Azure Stack, you must create a new VM group in SP13 or later and select the IntelliSnap option.

Backup Copies

For Feature Release 19 and more recent feature releases, when an IntelliSnap backup includes multiple VMs, if a backup copy job for a specific VM cannot be completed, the backup copy job goes to pending and then retries the backup copy operation, up to the maximum number of job attempts that is configured for the Job Manager. (By default, the number of job attempts is 10.)

Any backup copy jobs that do not complete successfully after the maximum number of attempts are marked as Completed with Errors. If backup copy jobs for any VMs do not complete successfully after the maximum number of attempts, the associated IntelliSnap backup job is marked as Completed with Errors.

For service packs prior to Feature Release 19, if a backup copy operation was successful for any VM in an IntelliSnap backup job, the IntelliSnap backup job was marked as Completed with Errors if backup copy operations were unsuccessful for other VMs that were part of the IntelliSnap backup job, and any unsuccessful backup copy operations for the remaining VMs were not retried.

Result

When you enable IntelliSnap on a VM group, Commvault automatically creates the following configurations:

  • Virtual Server Agent Snap is identified as the snap engine for Amazon snapshots.
  • Schedule policies are created for the primary (snap) and backup copies.
  • The server backup plan associated with the VM group has IntelliSnap enabled and is set to retain eight snap recovery points. (You can modify the server plan to specify a different number of snaps to retain.)
