The Block Level Backup Engine Service (wbengine) performs block-level backup and recovery of data. This service is used by the Backup and Restore feature in the Control Panel of Windows 7 and by the Windows Server Backup feature of Windows Server 2008 R2. It allows for backups to occur at the hard disk drive level, instead of by files, and it uses a process similar to disk imaging.
This service is installed by default and its startup type is Manual. When the Block Level Backup Engine Service is started in its default configuration, it logs on by using the Local System account.
This service is not dependent on any other system service, nor is any service dependent on it.
