You work as an enterprise administrator at Domain.com. The Domain.com network consists of a single Active Directory domain named Domain.com. All servers on the Domain.com network run Windows Server 2008.
Domain.com contains a server that has the Windows Backup and Restore utility installed. However, the Domain.com management wants to know which of the following command can be used to create a full backup of all system state data to the DVD drive (E: drive).

Explanation:
You need to run the Wbadmin start backup allCritical backuptarget :E : /quiet command to create a full backup of all system state data to the DVD drive.
