While designing Active Directory, disaster recovery plays a pivotal role. Active Directory backups create the foundation for full-on backup disaster recovery of an entire forest.  Selecting the precise Active Directory backup is critical for any disaster recovery plan. Windows server backup is available for full server backup, partial folders, or only selected volumes. Primarily, there are three ways to backup Active Directory. 

Active Directory Backups: Restoring a single domain controller to restore all DCs in a forest to ensure business continuity & disaster recovery; AD backup is the mainstay. 

Bare Metal Recovery Backups: BMR backup disaster recovery assists in restoring AD forest to different hardware instances in case of physical corruption. 

Azure AD Backups: A comprehensive IT backup & disaster recovery plan that includes a backup strategy for cloud & attributes alongside securing on-premises data.

Restoration of Active Directory servers is important to ensure an extensive backup disaster recovery process. For administrators, monitoring Event ID 4 & Event ID 14 is of utmost importance. While Event ID 4 notifies when a Windows backup is successful, the other contains the status of the backup. Serving as a central database that executes a huge volume of data, keeping it in a healthy condition is an ongoing activity.
