System State Backup
Server Manager :: Tools :: Windows Server Backup
Backing up an Active Directory installation, you can create a system state backup. The backups must be saved to another physical drive connected to the server – they cannot be done over a network share.
Start backup to D: drive:
wbadmin start systemstatebackup -backuptarget:d:
Logs about backups are saved to C:\Windows\Logs\
Volume Shadow Copy service must also be running.
services.msc
In case of errors, run diskshadow to see what files it may be failing on.
diskshadow /l out.txt list writers detailed exit notepad out.txt
