Consider the following recommendations when backing up a domain controller:
- Create a Windows backup set for every domain controller. You can only use the backup data from a domain controller to restore Active Directory to the same domain controller.
- Create Windows backup sets often enough to ensure that they are valid backups. If the date of your System State backup exceeds the maximum age limit set in Active Directory, the backups are not valid, and Windows 2000 prevents the restoration of Active Directory.
For detailed information about how to back up a Windows 2000 domain controller and the Active Directory information contained therein, see the technical paper
