Creating a User-Defined Subclient for IBM Spectrum Scale (GPFS)

Subclients contain information about what data is backed up. You can create a user-defined subclient to manage and back up specific data.

Procedure

  1. From the CommCell Browser, expand Client Computers > pseudo-client > Big Data Apps.
  2. Right-click the instance that you want to create a subclient for, point to All Tasks, and then click New Subclient.

    The Subclient Properties dialog box appears.

  3. Specify the basic settings for the subclient:
    1. In the Subclient Name box, type a name.
    2. On the Data Access Nodes tab, select the data access nodes that you want to add to the subclient, and then click Add.
    3. On the Content tab, click Browse to select the directory or file that you want to back up, and then click Add.

      Repeat this step to include all the files and directories that you want to back up.

      Note: The default subclient does not back up the content you specify in user-defined subclients that are within the same instance.

    4. Optional: If you want to use native GPFS snapshots for scan and backup operations, select the Use GPFS snapshot for scan and backup check box.
    5. Click Advanced.

      The Advanced Subclient Properties dialog box appears.

  4. On the Performance tab, specify the number of data streams:
    1. In the Number of Data Readers box, enter the number of data streams.

      Tip: For optimal sharing of the backup load, the number of data readers must be greater than the number of data access nodes.

    2. Select the Allow multiple data readers within a drive or mount point check box
    3. Click OK.
  5. On the Storage Device tab, select a storage policy from the Storage Policy list.
  6. To create a new storage policy, click Create Storage Policy and follow the instructions in the storage policy creation wizard.
  7. To perform LAN-free backup and restores, select a grid storage policy.

    For more information, see GridStor® (Alternate Data Paths) - Overview.

  8. Optional: Select the subclient options.
