Backup Stragety of Active Directory
Backup Strategy of Active Directory I would like to start by defining “backup” which is the process of making copies of data in case the original get lost or damaged. In today’s world having a good backup system is important for any company. A good backup includes at least the system state and the contents of the system disk. Backing up the system disk ensures that all the required system files and folders are present so you can successfully restore the data. When backing up an Active Directory at a minimum, back up two domain controllers in each domain, one of which should be an operations master role holder (excluding the relative ID (RID) master, which should not be restored). Furthermore, that backup data from a domain controller can only be used to restore that domain controller. You cannot use a backup of one domain controller to restore another. (technet.microsoft.com)
To recover a domain controller through reinstallation, you do not restore the system state from backup media; instead, you reinstall Windows, install Active Directory, and allow replication partners to bring the recovered domain controller up to date. Recovering a domain controller through reinstallation can quickly return the computer to service if the following conditions exist: First, a domain controller has failed and you cannot restart in Directory Services Restore mode. If failure was caused by a hardware failure, you have resolved the hardware problem (for example, by replacing the disk). Second, there are other domain controllers in the domain, to serve as replication partners. Third, the computer is functioning only as a domain controller (it does not run other server services such as Exchange), and it does not contain other data that needs to be recovered from a backup.

Monitoring is an essential part of server administration. By monitoring the server 's performance, you can spot problematic trends as they develop, and take steps to prevent them from
