Configuring Cluster Nodes for Block-Level Backups

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

Before You Begin

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

Procedure

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

    The CVBF driver is installed as part of the File System Agent installation. The CVBF driver monitors the volumes on the active node.

  2. Configure the Cluster Group client (virtual node) using the CommCell Console. For instructions, see Configuring Cluster Group Clients for Non-Veritas Clusters (UNIX).

    Note: In the Advanced Client Properties dialog box, on the Cluster Group Configuration tab, select both MediaAgent and File System on the Agents subtab.

  3. From the CommCell Browser, expand Client Computers > Client (virtual node) > File System.
  4. Right-click the appropriate backup set, point to All Tasks, and then click New Subclient.

    The Subclient Properties dialog box appears.

  5. On the General tab, in the Subclient Name box, type a name for the subclient.
  6. To set the content for the subclient, on the Content tab, click Browse to locate the content, and then click OK.

    Only a cluster mount point can be configured as subclient content for the virtual node. For disk file system mount points as subclient, you must use a proxy client for backups to run successfully.

  7. 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.

  8. Click Advanced.

    The Advanced Subclient Properties dialog box appears.

  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 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.
