Repairing DPM

Published : April 8, 2005 | Updated : August 17, 2005

In the unlikely event of corruption of the Windows registry, system files, Internet Information Services, or the DPM binaries, you can repair DPM by reinstalling the application. Reinstalling DPM involves uninstalling the application with an option to retain your data protection configuration selected, and then re-running Setup.

In most cases, you do not need to uninstall the DPM prerequisite software to reinstall DPM. However, if the SQL Server 2000 binaries become corrupted, you may need to uninstall and reinstall SQL Server 2000 as well.

You do not need to uninstall the DPM File Agent from the protected file servers to reinstall DPM.

Important

Before starting a reinstallation of DPM, we strongly suggest that you archive the DPM database, Report database, and replicas to tape or other removable storage medium. For instructions, see “Archiving a DPM Server” in the “Planning a Deployment” chapter of this guide; see also the DPM 2006 Operations Guide.

If you do not plan to reinstall DPM immediately after the uninstallation portion of the repair operation is complete, disable end-user recovery on the DPM server and run synchronization for each of the volumes in your protection groups. These steps help ensure that users to whom you deny access to files on the file server cannot access the replicas of those files on the DPM server.

Protection jobs cannot run successfully during a repair operation. Any jobs scheduled to run while a repair operation is in progress will not run. Any jobs that are in progress when the uninstallation portion of a repair operation begins are cancelled. Upon completion of a repair operation, DPM automatically attempts to perform any cancelled replica creation, synchronization, or consistency check jobs, but does not attempt to perform cancelled shadow copy creation jobs.

To repair DPM

  1. In Control Panel, click Add or Remove Programs, and then click Change or Remove Programs.

  2. Under Currently installed programs, select Microsoft Data Protection Manager 2006, and then click Change/Remove.

    The Setup wizard starts in uninstallation mode.

  3. On the Uninstall Options page, select Retain data, and then click Next.

  4. On the Summary of Options page, click Uninstall.

  5. After uninstallation is complete, start the DPM Setup wizard, and follow the instructions for installing DPM. Setup will automatically detect and use your existing DPM database.

  6. After the new installation is complete, start DPM Administrator Console, navigate to the Monitoring task area, and check for protection jobs that failed during the repair operation. Manually restart any failed jobs.
