Tech Tip: Make regular backups of the registry


Since the registry is the heart of a Windows server, it’s a good idea to back up the registry on a regular basis. This will help provide painless system restoration in the event of a failure.

There are many ways to accomplish this task. While the automatic methods are best, you can also use a manual method at will. Here are a few ways to back up the registry:

  • Use a good backup program: Most commercial backup utilities, such as BrightStor ARCserve Backup and Veritas BackupExec, can easily handle the task of backing up and restoring the registry on target systems in the network.
  • Create an emergency repair disk: You should periodically use Rdisk.exe to create emergency repair disks for all of your Windows servers. Run Rdisk.exe with the /s parameter to include security and SAM data on the disk. When the Rdisk.exe GUI appears, select Update Repair Info before you click Create Repair Disk.
  • Failure to do so will result in noncurrent security information.
  • Use the Windows NT backup utility: When you use the NT backup utility, make sure you select the Backup Local Registry option on the Backup Information window.
