It’s unbelievably that SysAdmin’s don’t backup your Active Director Domain controllers..
Execute the following schedule task to create a SystemState Backup on your DC’s
[source]schtasks /create /tn SYSTEMSTATE_BACKUP_DAILY /tr "ntbackup backup systemstate /J "%hostname%_SYSTEMSTATE_BACKUP" /F "E:\Backups\SYSTEMSTATE_BACKUP_%date:~4,2%%date:~7,2%%date:~10,4%.bkf" /V:yes" /sc daily /st 01:00:00 /ru "System" /rp[/source]
