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)
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.

And I'll introduce you both ways in the following.
