Creating a User-Defined Subclient for CIFS Shares

You can create a user-defined subclient to manage and back up specific shares and share contents. To add content to a user-defined subclient, you can browse for content or you can manually add content. If a CIFS share is marked as non-browsable on the file server, you must manually enter the path to the share.

If the content of subclients overlap, then the backup of each share is performed separately.

You can configure the data access nodes as backup nodes for the network share subclient. The backup operation runs on the selected nodes. You can set data access nodes at the agent level or at the subclient level. The nodes set at the subclient level take precedence.

Before You Begin

  • Verify that all Windows data access nodes have access and permissions to the CIFS share.
  • Verify that the impersonate user credentials have read and write permissions on the CIFS share. The same user credentials are used to back up the subclient and to browse for subclient content (not all file servers require credentials for browsing).
  • If you are creating a subclient whose content is CIFS shares from a non-default access zone, verify that the subclient content is from the same access zone.


  1. From the CommCell Browser, go to Client Computers > client > Windows File System.
  2. Right-click the backup set, and then go to All Tasks > 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, add the paths to the content that you want to back up.

    Option to add a path


    Browse and select the shares that are available on the file server

    1. Click Browse.

      The Browse Configuration dialog box appears.

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

      You can update the client host to a CIFS interface on the file server.

    3. From the Proxy list, click the proxy computer that must be used to browse the shares.
    4. If the file server does not allow browsing without credentials, complete the following steps:
      1. Click As User.

        The Impersonate User dialog box appears.

      2. Enter the credentials needed to access the file server.

        Note: These credentials are also used for the backup operation.

    5. Click OK.

      The Browsing contents dialog box appears.

    6. Click the CIFS share that you want to back up, and then click Add.

    Manually add a path

    1. Click Add Paths.

      The Add Multiple Contents dialog box appears.

    2. Type the path to the CIFS share or the share contents, and then click OK.

      You can include wildcards to define the subclient content. For example, to back up all shares that start with Dep, enter \\file_server\Dep*. To back up all shares from Dep1 to Dep10, enter \\file_server\Dep[1-10]. To back up all folders and files that start with Project under share Dep5, enter \\file_server\Dep5\Project*\**. All the sub-folders and files under these folders are backed up. For information about supported wildcards, see Wildcards for the Windows File System Agent.

      If credentials are needed, the Impersonate User dialog box appears. Enter the credentials needed to access the file server.

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

    Tip: To create a new storage policy, click Create Storage Policy, and then 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 (that contains Windows clients) from the available nodes list.
    • All the participating backup nodes must be at the same service pack level.
  7. On the Performance tab, verify that the Allow multiple readers within a drive or mount point check box is selected, and then increase the number of data readers based on the number of data access nodes added.
  8. On the Advanced Options tab, verify that the Reconcile Backup check box is selected.
  9. Click OK.
