Performing a Virtual Machine Backup

You can run an immediate backup to capture complete virtual machine information or to capture information that has changed since a previous backup.


For virtual machines that are hosted on an SMB share, a Microsoft limitation prevents restore operations from reading file and folder information from a snap backup. To enable restores of guest files and folders from Microsoft Hyper-V backups using a server plan, use the Collect file details option for the VM group.


  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 the name of the VM group that contains the virtual machines to back up.

  4. In the Backup area, click Back up now.

  5. In the Backup options dialog box:

    • Backup level: Select the backup type. (A full backup is always performed for the first backup of any virtual machine.)

      • Full: Perform a full backup for a virtual machine that has previously been backed up. A full backup includes virtual machine configuration files and all virtual machine data disks.

      • Incremental: Selected by default. An incremental backup only backs up changes since the last full backup.

      • Synthetic full: Create a synthesized backup from the most recent full backup and all subsequent incremental backups.

        An incremental backup is performed first to ensure that the synthetic full backup will be up to date.

        The resulting synthetic full backup is identical to a full backup for the VM group. Unlike full and incremental, a synthetic full backup does not actually transfer data from a client computer to the backup media, and does not use any resources on the client computer.

  6. Click OK to begin the backup operation.


The backup operation runs and alerts are triggered based on the success or failure of the backup job. To view the alerts created for your virtual machine backup jobs, go to the Triggered alerts page and filter on the following alert definitions:

  • VM Backup succeeded

  • VM Backup failed

  • VM Backup succeeded with errors

For information about alerts, see Alerts.
