Creating User-Defined Subclients for CIFS Shares

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

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 Nutanix Files 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 in such cases.

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 non-default access zone, verify that the subclient content is from the same access zone.


  1. From the CommCell Browser, expand Client Computers > client > Windows File System.
  2. Right-click the 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, add the paths to the content you want to back up:
    1. To browse and select the shares available on the on file server, click Browse.

      The Browse Configuration dialog box appears.

      1. From the Proxy list, click the proxy to use to browse for the shares.
      2. If the file server does not allow browsing without credentials, click As User, and then, in the Impersonate User dialog box, enter the credentials needed to access the file server.

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

      3. Click OK.

        The Browsing contents dialog appears.

      4. Click the CIFS share that you want to backup, and then click Add.

        You can select a standard share or a distributed share on the file server.

        Note: Only the CFT backup enabled shares are included in backups.

      5. Click Close.
  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 Windows clients) from the available nodes list.
    • To reduce scan times by using the Change File Tracking (CFT) API for Nutanix Files, you must select a minimum of two data access nodes.
    • All of the participating backup nodes must be at the same service pack level.
    • 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.
  7. Click OK.
