Configuring Cluster Nodes for Windows File System Agent Block-Level Backups

You can configure and manage block-level backups on Windows Cluster Group Clients.

Before You Begin

Verify that the computer that in which you wish to install the software satisfies the minimum requirements specified in System Requirements for Block-Level Backup.

Procedure

  1. Install the MediaAgent on all the physical nodes that you want to protect in your cluster environment. For more information, see Installing the MediaAgent.

    Note: The VSS Provider package and the File System Agent are installed as part of the MediaAgent installation. Make sure that you do not exclude the VSS Provider check box during the installation.

  2. Configure the Cluster Group client using the CommCell Console. For instructions, see Configuring Agents on Microsoft Cluster.
  3. From the CommCell Browser, choose whether to configure the default subclient or to set up a user-defined subclient:
    • To configure the default subclient of the Windows File System Agent:
      1. Expand Client Computers > Client (virtual_node) > File System > backup_set.
      2. Right-click the default subclient and then click Properties.
    • To set up a user-defined subclient of the Windows File System Agent:
      1. Expand Client Computers > Client (virtual_node) > File System.
      2. Right-click the appropriate backup set, point to All Tasks, and then click New Subclient.
  4. On the General tab, in the Subclient box, type a name for the subclient.
  5. To set the content for the subclient, on the Content tab, click Browse to locate the content, and then click OK.

    Notes:

    • The subclient content must consist of cluster disks.
    • You cannot enable OnePass for the subclient configured to perform block-level backups.
  6. On the Storage Device tab, from the Storage Policy list, select an appropriate storage policy. For native snapshot engines, use a storage policy that does not have a snapshot copy configured on it.
  7. Click Advanced.
  8. In the Advanced Subclient Properties dialog box, click the Advanced Options tab.
  9. On the Advanced Options tab, set up your block-level backup:
    1. To enable block-level backup, select the Optimized for File system with large number of small files (Block-Level Backup) check box.
    2. To install the block filter driver, select the Install block filter driver check box.

      Notes:

      • This operation is irreversible and you cannot uninstall block filter driver at a later time. All backups run as Full backups until you restart your computer.
      • The Install block filter driver check box is displayed for the first subclient you configure. Once you click OK, the option will not be displayed in any subclient residing under the client computers node.
      • You must install the block filter driver on all nodes. During the installation of the block filter driver, if the install fails on any one the nodes, log on to the physical node and install the block filter driver.
      • If the backups failover to a node that was not restarted after installing the block filter driver, the backups are run as Full backups.
    3. To perform file-level browse faster, select the Create File level Index during backup check box.

      Backups may take longer when you enable this option depending on the data scan type selected.

      Scan Type

      Effect

      Recursive Scan

      A file system scan is used to determine the modified data, resulting in a longer completion time.

      Optimized Scan

      A customized database that contains information about the files is used to quickly determine the modified data, resulting in a reduced scan time.

  10. Select additional options as appropriate for subclient creation and click OK.

    The new subclient appears under defaultBackupSet node.

What To Do Next
