Maintaining an AD DS Database is an important administrative task that you must schedule regular to ensure that, in the case of disaster. You can recover lost or corrupted data and repair the AD DS Database.

The AD DS has its own database engine, the Extensible Storage Engine (ESE), which manages the storage of all AD DS objects in an AD DS database. The AD DS database is stored as a file name Ntds.dit. When you install and configure AD DS, you can specify the location of the file. The default location is %SystemRoot%NTDS.

AD DS includes the following files as in figure.

You can back up AD DS by using Windows Server Backup, Wbadmin.exe or PowerShell. Depending on the roles installed on the computer running Windows Server 2012 R2, the System State Data on a Domain Controller includes the following components:

  • Active Directory Database (Ntds.dit)
  • The SYSVOL shared folder
