Overview of system state backup domain controller

Active Directory is backed up as part of the system state, a collection of interdependent system components, thus you need to back up and restore system state components together. On a domain controller, the system state backup consists of the following files:

  • Boot files, including system files and all files protected by Windows File Protection (WFP)

  • Active Directory 

  • Windows registry

  • Sysvol 

  • Class registration database of Component Services

And it responds to security authentication requests (logging in, checking permissions, etc) within a Windows domain. The loss of a domain controller can cause a denial of service (DoS) and finally, your network service can't work normally as before. Anyway, you need to make a Windows 2012 R2 domain controller system state backup when it works well.

Besides, there is another complete backup - system backup, which backs up all the data on the system drive, including the operating system, system settings, boot files, installed programs, personal data, etc. To protect system safety, it will be a better choice. And I'll introduce you both ways in the following.
