Use the Wbadmin Backup Command Line Utility in Windows Server 2008
Wbadmin is the command-line counterpart to Windows Server Backup. You use Wbadmin to
manage all aspects of backup configuration that you would otherwise manage in Windows
Server Backup. This means that you can typically use either tool to manage backup and
recovery.
After you’ve installed the Backup Command-Line Tools feature, you can use Wbadmin to
manage backup and recovery. Wbadmin is located in the %SystemRoot%\System32\
directory. As this directory is in your command path by default, you do not need to add this
directory to your command path.

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

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, Windows Vista, Windows Server 2008 R2, or Windows 7 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, Windows Vista, Windows Server 2008 R2, or Windows 7 to
create new backups.
