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.
