How can I perform a System State Restore from my Barracuda Backup Service on a Windows 2008 server?

  • Type: Knowledgebase
  • Date changed: 6 years ago

Solution #00005639

Scope:
This solution applies to all Barracuda Backup Servers, firmware version 3.1 and higher.


This solution applies to restoring System State backups on Windows 2008, if restoring Windows 2003, please reference solution #00005638.



Answer:

This document assumes that System State backups exist and Directory Services Restore Mode (DSRM) password is available to the person restoring.

Restore Windows Server System State:

Restoring System State should only be performed in a disaster recovery situation. This is typically if a server goes down and is not recoverable or if the configuration is severely corrupted.

This procedure should only be started if you can meet the following requirements:

  • Barracuda Backup Agent is installed on TARGET server.

  • Backups of all File System, and System State from the SOURCE server exist.

  • Server hardware and operating system are configured like the SOURCE server that you wish to restore.

  • The TARGET server is on the network and can communicate directly with the Barracuda Backup Server (you cannot perform this restore procedure from the Cloud).

For Active Directory domain controllers:

  • The IP address is set to be the same as the original server that you are restoring (recommended).

  • Access to the Directory Services Restore Mode password.


Prepare a Target Windows 2008 Server:

1. Set up the Target server to be as identical as possible to the Source server that was backed up, including the same version, edition, and bits. For example, if the Source server was Windows 2003 R2 Enterprise on 32 bit, the Target server should be the same.
2. Power up the Target server and let it boot normally.
3. Logon with the Administrator account or your own account with administrative access to this server. If the Target server is already a domain controller, use a domain account with administrative access to this server.
4. When logged in, click Start and then under Search programs and files type cmd and press Enter. This will open a command prompt.

5. In the command prompt type:

  • bcdedit /set safeboot dsrepair

  • IMPORTANT: The next step will restart your server.

6. Press Enter then type the following:










shutdown -r -t 1


7. Press Enter. The server will restart.
8. You will see a diagnostic startup as Windows boots into Directory Services Repair mode.
9. When the server boots, press Ctrl-Alt-Delete to log in.
10. Use the Administrator password (or Directory Services Restore Mode password if this is an AD domain controller).
11. Once the server has booted, make sure the Barracuda Backup Agent is running by clicking Start and typing services.msc in the Search programs and files field. Press Enter.

12. The Barracuda Backup Agent should show that it is started:






13. If the service is not listed, it must be installed before continuing.

14. If the service is listed, but not started, click the Barracuda Backup Agent then click the Start the service link:











NOTE: If you decide not to restore to this server, perform the steps in the section Post-restore Tasks for Windows 2008 below. This will return your server to a normal boot mode.


Restoring Both File System and System State

Perform this procedure if you are restoring an Active Directory domain controller to the Target server or wish to restore a complete copy of the Source server (even if it did not have Active Directory).


IMPORTANT: This procedure will restore the file system as well, so files will be overwritten with those from the restored job!


IMPORTANT: Restoring System State from a Source domain controller will also restore Active Directory as it was on that server. Check with your system administrator before restoring a domain controller that is from an old revision backup.


1. Open the Barracuda Backup web configuration page by going to http://backup.barracudanetworks.com.


2. Logon with your account name and password:


















3. After logging on, click the Restore tab:








4. On the left pane of the Restore Browser, click the Windows server that represents the Source server you want to restore:







5. Click View all revisions up to: <date>
6. A list of revisions will appear.

7. Click Restore on the date that you wish to restore.








8. If the Target server is set up with the same IP as the Source server you are restoring, select Original Location.





















9. If the Target server is at a different location, select the third option and type the IP address of the new location in the field provided.







10. Click Start Restoring.

11. A dialog box will appear letting you know the restore job has been started. Click OK.

12. To view the state of the restore job, click the Reports tab under the Restore section:









13. The new restore job will be listed. Depending on the size of the original server, the restore job could take a while to complete.


Restoring System State

Perform this procedure if you only want to restore System State to the Target server, without restoring the rest of the file system as it was on the Source server. This procedure will restore system files, such as those in the C:\Windows folder, since that is part of System State. Perform these steps if you are not performing full disaster recovery and want to keep the Target server's file system intact.


IMPORTANT: Restoring System State from a Source domain controller will also restore Active Directory as it was on that server. Check with your system administrator before restoring a domain controller that is from an old revision backup.


NOTE: Since this section does not restore file systems, following these steps will not restore replicated file systems or administration tools if the Source server was a domain controller. This means group policy objects and logon scripts will not be available on the Target unless they are already on that server or on another server on the network. To restore these, follow the complete restore procedure above (Restoring Both File System and System State) or restore them manually from another server on the network.
