Recover Data - OnePass for NetApp


  1. Verify that the Impersonate User login credentials given in step-9 during configuration is added to the Administrators group on the NetApp file server.
  2. Make sure that the proxy computer resides on the same domain as that of the file server.
  3. If you are using a file server version of 8.0.1, we recommend you to upgrade the version to 8.0.2.
  4. If you have Windows 2008 operating system, make sure that you specify the fully qualified domain name to authenticate the proxy computer with the file server.
  5. On the proxy computer, verify if the following conditions are setup:
    1. Firewall is disabled.
    2. NetBIOS over TCP is enabled.
    3. File and printer sharing for Microsoft Networks is enabled.
    4. In the Network access: Named Pipes that can be accessed anonymously setting, specify the pipe names, ntaptprq and ntapfpcp. The Network access: Named Pipes that can be accessed anonymously setting is available at the following location:

      GPO_name\Computer Configuration\Windows Settings\Security Settings\Local Policies\Security Options.

      For more information, see Network access: Named Pipes that can be accessed anonymously.

Recalling Data

The Commvault software provides two methods for recovering data that has been archived from a NetApp NAS file server.

Method 1: If FPolicy is Turned On

To recall archived data from its stub if FPolicy is turned on, follow these steps:

  1. Log on to a client computer that has UNC access to the stubs on the file server, or has a mapped network drive to the share.
  2. Using Windows Explorer, navigate to the folder containing the stubs.
  3. Double-click a stub. Note that it may take a few minutes for the recovered file to appear after double-clicking its stub.

Method 2: Using the Explorer Plug-In

If FPolicy is turned off, you can recall archived data through the Explorer Plug-In.

  1. If your Explorer Plug-In is not already enabled, enable it using these steps:
    1. Follow the steps given in Enable Explorer Plug-In - Driverless OnePass for Windows File System.
    2. If you cannot see the Recall Data option for the Edge menu, contact your administrator to confirm that your client computer is set up and a subclient has been created as described in Configuration - Driverless OnePass for Windows File System.
    3. Run one backup job for the subclient. See Archive - Driverless OnePass for Windows File System.
  2. In Windows Explorer, enter the UNC path where your archived data resides.
  3. Locate the data to recall, then:
    • Recall one file by right-clicking the file, then clicking Edge | Recall Data.
    • Recall a folder and all the data it contains (but not its sub-folders) by right-clicking the folder, then clicking Edge | Recall Data.
    • Recall a folder and all the data it contains, including all its sub-folders and their contents, by right-clicking the folder, then clicking Edge | Recall Data Recursively.

    These three methods support selecting multiple files or folders using the CTRL and SHIFT keys.

  • It may take a few minutes for the recovered data to appear.

Important Consideration

Verify if the tape is exported before attempting a recall job. To verify the tape, add the nRETRY_RECALL_CHECK_ISTAPEEXPORTED_BEFORE_RECALL additional setting on the MediaAgent computer as shown in the following table.

For instructions on adding the additional settings from the CommCell Console, see Add or Modify an Additional Setting.

Restore Data

Use the following method to restore:

  • Deleted files
  • Deleted stubs that are not yet aged
  1. From the CommCell Console, navigate to <Client> | NAS Client | File System

    Right-click the subclient that contains the data you want to restore and point to Browse and Restore.

  2. Click View Content.

  3. Select the folder level under the backup set. Its entire contents will be automatically selected in the right pane.

    Click Recover All Selected.

  4. The data which you want to restore may have been stubbed. In such scenario, by default the stub files are restored. If you wish to restore the data instead of the stub file, select Restore data instead of stub.

    Make sure that the Impersonate User checkbox is enabled. Enter the user name and password that you entered in Step 9 during configuration.

    Click OK.

  5. You can monitor the progress of the restore job in the Job Controller or Event Viewer window of the CommCell Console.

  6. Once job is complete, view the details of job from the Restore History.

    Right-click the defaultBackupSet and select View | Restore History.

    Click OK.

  7. Right-click the job and select View Job Details.

Congratulations -  You have successfully completed your first Archive and stub recovery.
