Creating a Subclient

To provide protection for a specific set of virtual machines, create a subclient. A user-defined subclient can identify virtual machines that have the same Service Level Agreement (SLA) or that need to be backed up on the same schedule.

Note: The default subclient is preconfigured to back up all virtual machines for the virtualization client that are not protected by other subclients. To change that behavior, see Modifying a Subclient.

Before You Begin


  1. From the CommCell Browser, navigate to Client Computers > virtualization_client > Virtual Server > VMware.
  2. Right-click a backup set and click New Subclient.
  3. Provide basic information on the General tab:
    1. Enter the Subclient name.
    2. By default the Transport Mode for VMware is set to Auto; the transport mode is selected automatically depending on the proxy computer used for backup and the virtual machines included in the backup.

      To use a specific transport mode, select one of the following:

      • SAN
      • Hot Add
      • NBD
      • NBD SSL

      For more information, see Transport Modes.

  4. Identify virtual machines to back up:
    1. Click the Content tab.
    2. Click Browse.
    3. Navigate to one or more virtual machines and select them.

      Note: If you have deployed MediaAgents, VSA proxies, or vCenter on virtual machines, filter those virtual machines from VSA backups. (If you need to protect files on those virtual machines, install in-guest agents on those virtual machine to perform file backups.)

    4. Click OK.

      The selected virtual machines are displayed in the Contents of subclient list.

    You can also define rules to select or exclude virtual machines based on various criteria; see Virtual Machine Discovery and Filtering.

  5. Click the Storage Device tab.
  6. Select a Storage Policy.
  7. Click OK.
  8. In the Backup Schedule dialog box, click Do Not Schedule, and then click OK.
