Microsoft replaced the ntbackup.exe backup utility in 2008 and Vista with wbadmin.

Wbadmin enables you to back up and restore your operating system, volumes, files, folders, and applications from a command prompt.

To configure a backup schedule, you must be a member of the Administrators group. To perform all other tasks with this command, you must be a member of the Backup Operators or the Administrators group, or you must have been delegated the appropriate permissions.

You must run wbadmin from an elevated command prompt. (To open an elevated command prompt, click Start, right-click Command Prompt, and then click Run as administrator.)

For more information on wbadmin go to this Microsoft TechNet page.

Remarks

The wbadmin command replaces the ntbackup command that was released with previous versions of Windows. You cannot recover backups that you created with ntbackup by using wbadmin. However, a version of ntbackup is available as a download for Windows Server 2008 and Windows Vista users who want to recover backups that they created using ntbackup. This downloadable version of ntbackup enables you to perform recoveries only of legacy backups, and it cannot be used on computers running Windows Server 2008 or Windows Vista to create new backups. To download this version of ntbackup, see http://go.microsoft.com/fwlink/?LinkId=82917.
