# Recovering Windows File System Data

Recover the entire file system data to the same or different client in the event of a disaster.

## Before You Begin

- When restoring a domain controller machine, restart the computer in Directory Services mode after installing the Windows File System Agent. Open Run > msconfig, and on the Boot tab, select the Safe boot check box and select Active Directory repair. Restart the computer when you receive a prompt.

- If performing an Authoritative restore for Cluster Database, ensure that the cluster services are stopped on all the other nodes of the cluster.

## Procedure

1. From the CommCell Browser, navigate to Client Computers > client > File System.

2. Right-click the<backupset> that contains the System State data and all the drives, point to All Tasks and then click Browse and Restore.

3. Select the required options from the Restore Options dialog box and click View Content.

4. Select the backup set box from the CommCell Browser which contains system state data and all the drives.

5. Click Recover All Selected.

6. Select the required options from the Restore Options for All Selected Items dialog box and click OK.

   - If restoring on a domain controller, select one of the following from the Restore option for SYSVOL list:

     - Primary - Select this option when you are restoring for a standalone domain controller or the first domain controller restored in the network

     - Non-Authoritative - Select this option to restore the domain controller without replicating any changes to the other domain controllers on the network

     - Authoritative - Select this option to restore the domain controller and also replicate any changes to the other domain controllers on the network. You must run the ntdsutil to replicate the changes to the other domain controllers.

   - If restoring a cluster on Windows Server 2008 and later, select one of the following from the Allow Authoritative for Cluster Database list:

     - Authoritative

     - Non-Authoritative

   - Do not select Unconditional Overwrite option if the hardware of the destination computer is drastically different than the hardware of the source computer.

7. Click Compare to view the Service Pack information of source and destination computer.

8. Note down the service packs that are not installed on the destination computer and click Close.

9. Click No if the source computer and the destination computer have different versions of Windows operating system service packs.

   Install the required versions of operating system service packs and hot fixes on the destination computer.

   Note

   It is strongly recommended to ensure that the patch level of the installed OS matches with that of the backup image, as otherwise, the restored system may not boot.

10. Click Yes if all the service packs on the source and destination computer are same. The full system restore starts.

11. Click OK to restart the computer.

12. Re-install any agents that were previously installed on the restored client computer.

13. Enable backup jobs on the client:

    1. From the CommCell Browser, right-click the client, and then select Properties.

    2. Click the Activity Control tab.

    3. Clear the Enable Backup check box and click OK.

14. For a non-authoritative restore of cluster on Windows Server 2008 and later, remove the computer from the Directory Services Restore Mode (DSRM), and restart the computer in normal mode.

    Enter Y (yes) for the following message:

        Full iDataAgent Restore job completed. Do you want to reboot?

15. On a Windows Server 2008 and later, select Configure Refresh from the Server Manager main page and update Features and Roles as they are not updated during a restart.

16. For authoritative restore of cluster on Windows 2008 and later:

    1. Ensure that the cluster services are stopped on all the other nodes of the cluster. If required, stop the cluster services on all the other nodes.

    2. Enter Y (yes) for the following message:

           Full iDataAgent Restore job completed. Do you want to reboot?

    3. Start the services on all the other nodes in the clusters.
