When you use Windows 2000 Backup to back up the System State data of a domain controller, the Active Directory database is backed up as well.
For more information about System State backups, see Windows 2000 System State Data.

Although backing up the System State of a domain controller running Active Directory involves backing up additional files, you use the same procedure for backing up the System State of a domain controller as you would for a server that is not a domain controller.
In addition to backing up the System State data of your domain controller, you must also back up the Windows boot partition and system partition as part of the Windows backup set.

A System State data backup performed on a domain controller includes the backup of Active Directory database and log files and all other files for the system components and services on which Active Directory is dependant.

The following Active Directory files are part of a System State data backup performed on a domain controller. By default, these files are located in the Active Directory folder in %SystemRoot%\Ntds:

• Ntds.dit The Active Directory database
• Edb.chk The checkpoint file
• Edb*.log The transaction logs; each 10 megabytes (MB) in size
• Res1.log and Res2.log The reserved transaction logs
