Backup and restore of the domain

The enterprise domain holds user accounts and passwords, and in order to keep these important data from being lost, the data in the domain should be backed up and restored.

Preparation conditions: 2 Hard drives (one is the system disk, one is the disk used to do the domain data storage)

Experimental ideas: Take uec.com as an example. Install the Windows Server Backup component to back up the system state. The account of the simulated domain is deleted, enters the safe mode, does the directory service Repair mode, restores the domain data
