FAQs about Windows System Backup

What is the difference between Windows Server System State, Windows System Backup, and Disk Image?


System State is a feature of Windows Server to back up Active Directory and other system state data. It produces a small sized file in vhd format that can be reimported into a running Windows Server instance using official Microsoft tooling. It requires temporary spool space.

Windows System Backup produces a backup of the entire hard drive in vhd format. It requires temporary spool space.

Disk Image produces a backup of the entire hard drive in vmdk format, that can be used for bare metal restore. It does not require temporary spool space and can stream the backup data directly to your storage location.

When should I use Disk Image or Windows System Backup?
