Non-authoritative restore is the default method for restoring Active Directory.

Non-authoritative restore of SYSVOL

When you non-authoritatively restore the SYSVOL, the local copy of SYSVOL on the restored domain controller is compared with that of its replication partners. After the domain controller restarts, it contacts its replication partners, compares SYSVOL information, and replicate the any necessary changes, bringing it up-to-date with the other domain controllers within the domain.

Perform a non-authoritative restore of SYSVOL if at least one other functioning domain controller exists in the domain. This is the default method for restoring SYSVOL and occurs automatically if you perform a non-authoritative restore of the Active Directory.

If no other functioning domain controller exists in the domain, then perform a primary restore of the SYSVOL. A primary restore builds a new File Replication service (FRS) database by loading the data present under SYSVOL on the local domain controller. This method is the same as a non-authoritative restore, except that the SYSVOL is marked primary.

What is the difference between authoritative and non-authoritative restore?

A nonauthoritative restore is the default method for restoring Active Directory. To perform a nonauthoritative restore, you must be able to start the domain controller in Directory Services Restore Mode. After you restore the domain controller from backup, replication partners use the standard replication protocols to update Active Directory and associated information on the restored domain controller. An authoritative restore brings a domain or a container back to the state it was in at the time of backup and overwrites all changes made since the backup. If you do not want to replicate the changes that have been made subsequent to the last backup operation, you must perform an authoritative restore. In this one needs to stop the inbound replication first before performing the An authoritative restore.

Backing up Active Directory is essential to maintain an Active Directory database. You can back up Active Directory by using the Graphical User Interface (GUI) and command-line tools that the Windows Server 2003 family provides. You frequently backup the system state data on domain controllers so that you can restore the most current data. By establishing a regular backup schedule, you have a better chance of recovering data when necessary. To ensure a good backup includes at least the system state data and contents of the system disk, you must be aware of the tombstone lifetime. By default, the tombstone is 60 days. Any backup older than 60 days is not a good backup. Plan to backup at least two domain controllers in each domain, one of at least one backup to enable an authoritative restore of the data when necessary. System State Data Several features in the windows server 2003 family make it easy to backup Active Directory. You can backup Active Directory while the server is online and other network function can continue to function. System state data on a domain controller includes the following components: Active Directory system state data does not contain Active Directory unless the server, on which you are backing up the system state data, is a domain controller. Active Directory is present only on domain controllers. The SYSVOL shared folder: This shared folder contains Group policy templates and logon scripts. The SYSVOL shared folder is present only on domain controllers. The Registry: This database repository contains information about the computer's configuration. System startup files: Windows Server 2003 requires these files during its initial startup phase. They include the boot and system files that are under windows file protection and used by windows to load, configure, and run the operating system. The COM+ Class Registration database: The Class registration is a database of information about Component Services applications. The Certificate Services database: This database contains certificates that a server running Windows server 2003 uses to authenticate users. The Certificate Services database is present only if the server is operating as a certificate server. System state data contains most elements of a system's configuration, but it may not include all of the information that you require recovering data from a system failure. Therefore, be sure to backup all boot and system volumes, including the System State, when you back up your server. Restoring Active Directory In Windows Server 2003 family, you can restore the Active Directory database if it becomes corrupted or is destroyed because of hardware or software failures. You must restore the Active Directory database when objects in Active Directory are changed or deleted. Active Directory restore can be performed in several ways. Replication synchronizes the latest changes from every other replication partner. Once the replication is finished each partner has an updated version of Active Directory. There is another way to get these latest updates by Backup utility to restore replicated data from a backup copy. For this restore you don't need to configure again your domain controller or no need to install the operating system from scratch. Active Directory Restore Methods You can use one of the three methods to restore Active Directory from backup media: primary restore, normal (non authoritative) restore, and authoritative restore. Primary restore: This method rebuilds the first domain controller in a domain when there is no other way to rebuild the domain. Perform a primary restore only when all the domain controllers in the domain are lost, and you want to rebuild the domain from the backup. Members of Administrators group can perform the primary restore on local computer, or user should have been delegated with this responsibility to perform restore. On a domain controller only Domain Admins can perform this restore. Normal restore: This method reinstates the Active Directory data to the state before the backup, and then updates the data through the normal replication process. Perform a normal restore for a single domain controller to a previously known good state. Authoritative restore: You perform this method in tandem with a normal restore. An authoritative restore marks specific data as current and prevents the replication from overwriting that data. The authoritative data is then replicated through the domain. Perform an authoritative restore individual object in a domain that has multiple domain controllers. When you perform an authoritative restore, you lose all changes to the restore object that occurred after the backup. Ntdsutil is a command line utility to perform an authoritative restore along with windows server 2003 system utilities. The Ntdsutil command-line tool is an executable file that you use to mark Active Directory objects as authoritative so that they receive a higher version recently changed data on other domain controllers does not overwrite system state data during replication.
