Backup Windows Server 2003 Active Directory Backing up Active Directory is essential to maintain the proper health of the Active Directory database. You can backup Active Directory by using the NTBACKUP tool that comes built-in with Windows Server 2003, or use any 3rd-party tool that supports this feature. Backing up the Active Directory is done on one or more of your Active Directory domain Controllers (or DCs), and is performed by backing up the System State on those servers. The System State contains the local Registry, COM+ Class Registration Database, the System Boot Files, certificates from Certificate Server (if it's installed), Cluster database (if it's installed), NTDS.DIT, and the SYSVOL folder . Method #1: Using NTBACKUP Open NTBACKUP by either going to Run, then NTBACKUP and pressing Enter or by going to  Start -> Accessories -> System Tools. If you are prompted by the Backup or Restore Wizard, I suggest you un-check the "Always Start in Wizard Mode" checkbox, and click on the Advanced Mode link. Inside NTBACKUP's main window, click on the Backup tab. Click to select the System State checkbox. Note you cannot manually select components of the System State backup. It's all or nothing. Enter a backup path for the BKF file. If you're using a tape device, make sure NTBACKUP is aware and properly configured to use it. Press Start Backup. The Backup Job Information pops out, allowing you to configure a scheduled backup job and other settings. For the System State backup, do not change any of the other settings except the schedule, if so desired. When done, press Start Backup. After a few moments of configuration tasks, NTBACKUP will begin the backup job. When the backup is complete, review the output and close NTBACKUP. Next, you need to properly label and secure the backup file/tape and if possible, store a copy of it on a remote and secure location. Method #2: Using the Command Prompt You can use the command line version of NTBACKUP in order to perform backups from the Command Prompt. For example, to create a backup job named "System State Backup Job" that backs up the System State data to the file D:\system_state_backup.bkf, type: ntbackup backup systemstate /J "System State Backup Job" /F "D:\system_state_backup.bkf" For Microsoft's official documentation on Active Directory backups, see: Active Directory Operations Guide - Active Directory Backup and Restore
