Question

Explain the way to back-up active directory.

Answer 1

Backing up Active Directory is necessary to keep an Active Directory database. You can do this back up Active Directory using the Graphical User Interface (GUI) and command-line tools which the Windows Server 2003 family gives.

You often backup the system state data on domain controllers then you can restore the most current data. Through establishing a regular backup schedule, you contain a better chance of recovering data while necessary.
To make sure a good backup includes at least the system state data and contents of the system disk, you should be aware of the tombstone lifetime. The tombstone is 60 days, by default. Any backup older than 60 days is not a fine backup. Plan to backup at least two domain controllers in all domains, one of at least one backup to allow an authoritative restore of the data when essential.
