Creating a Subclient with Auto-mount Contents for NFS Exports

Applies To: Content paths that begin with the file server interface

When you add content to a subclient, if the content path uses the following format: file_server_interface:/NFS_export_path, then the backup operation can automatically mount the appropriate NFS export. The file server interface can be the host name or the IP address. To add content to the subclient, you can browse for content or you can manually add content.


  • There are two formats to add content to subclients:
    • Auto-mount format: The content path begins with the file server interface: for example, file_server_interface:/NFS_export_path.
    • Mount point format: The content path includes the mount point: for example, /mount/nfs.in
  • A subclient cannot contain a mix of content formats. To start using the auto-mount format, create a new subclient.
  • You cannot switch the subclient content from auto-mount format to mount point format or vice-versa.
  • For newly created subclients, the subclient content format defaults to the auto-mount format. If you want to specify the subclient content in mount point format, then add paths manually.
  • For an existing subclient, the browse type is determined based on the subclient content that is already present. If the subclient content is in auto-mount format, then the browse operation shows exports on the file server. If the subclient content is in mount point format, then the browse operation shows the proxy contents.

Before You Begin

  • If you browse for subclient content, verify that the proxy client that you use to browse for the exports has the permissions to mount the NFS export.
  • The in-place restore operation is not supported.


  1. From the CommCell Browser, expand Client Computers > NAS client > file system, right-click defaultBackupSet, point to All Tasks, and then click New Subclient.

    The Subclient Properties dialog box appears.

  2. In the Subclient Name box, type a name for the new subclient.
  3. On the Content tab, add the paths to the content you want to back up:
    • To browse and select the NFS exports available on the file server, click Browse.

      The Browse Configuration dialog box appears.

      1. In the File Server Interface box, review the default value (client host name).

        You can update the default value to an NFS interface on the file server.

      2. From the Proxy list, click the proxy to use to browse for the exports.
      3. Click OK.

        The Browsing contents dialog appears.

      4. Click the NFS export that you want to backup, and then click Add.
    • To manually add a path, click Add Paths, and then type the following:



      • file_server_interface is the NFS interface from the file server used when the NFS export is automatically mounted. The file server interface can be the host name or the IP address.
  4. 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.

  5. 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.
  6. Click OK.
