Proper Backup of Open Files Using Ntbackup

RESOLUTION

WARNING: If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.

Perform one of the following to resolve this problem:

• Set the following value to 0:

  HKEY_CURRENT_USER\SOFTWARE\Microsoft\Ntbackup\Backup Engine\Backup files inuse

• Make sure a consistent file is available for backup before you start the backup. To do this, perform one of the following:
  • Application method
    Use a utility for that application file that creates a good backup while that file is open. For example, rdisk -s backs up the registry in the %SystemRoot%\Repair folder.
    
    NOTE: When performing a remote backup of any server's registry, you must run rdisk -s or rdisk /s- on that server first because remote registries are not available to be backed up over the network.
  • System method
    Close the files before backup (for example, stop logons, close current sessions with existing clients, and stop all non-essential services). You may be able to accomplish this by using the AT command or the Command Scheduler (Winat.exe).
  • Application and System method
    The best approach may be to use both methods to make sure all data is accessible from a backup and to test your plan fully before implementing it.
