Creating User-Defined Subclient for NFS Exports

When you create a Network Share pseudo-client, a default backup set is automatically created, which contains a default subclient. The default subclient does not contain any content by default. You can add content to the default subclient.

You can also add additional subclients as needed to back up data within the backup set. If the content of subclients overlap, then the backup of each share is done individually.

You can configure the data access nodes as backup nodes for the Network Share subclient. The backup operation runs on the selected nodes.

Tip: You can set data access nodes at the agent level or at the subclient level. The nodes set at the subclient level take precedence in such cases.

Before You Begin

  • Mount the NFS export from the file server.

    Example: To mount a volume named vol_abc from a file server at to a mount point named /test, the command would be:

    mount 19922944 185856 19737088 1% /test

  • Verify that the NFS export is mounted in the same directory on all the Linux data access nodes.


  1. From the CommCell Browser, expand Client Computers > pseudo-client > Linux File System.
  2. Right-click backup_set, point to All Tasks, and then click New Subclient.

    The Subclient Properties dialog box appears.

  3. In the Subclient Name box, type a name for the new subclient.
  4. On the Content tab, click Add Paths and type the mount path where the NFS export is mounted on all the data access nodes.

    Alternatively, you can click Browse and select the mount path where the NFS export is mounted on all the data access nodes as content for backup. The content from the first data access node selected on the Backup Nodes tab at the agent level is displayed.

  5. On the Storage Device tab, in the Storage Policy list, click a storage policy name to associate with the subclient.

    Tip: To create a new storage policy, click Create Storage Policy and follow the instructions in the storage policy creation wizard.

  6. On the Data Access Nodes tab, under Available Data Access Nodes, select the data access nodes that will participate in the backup operation, and then click Add.


    • You can select a client or a client group (containing Linux clients) from the available nodes list.
    • On the Performance tab, ensure that you select the Allow multiple readers within a drive or mount point check box, and then increase the number of data readers as needed based on the number of data access nodes added.
    • On the Advanced Options tab, ensure that you select the Reconcile Backup check box.
    • All of the participating backup nodes must be at the same service pack level.
  7. Click OK.
