WBU meaning in Computing ?

Backup and Restore (formerly Backup and Restore Center) is the primary backup component of Windows Vista and Windows 7. It can create file and folder backups, as well as system images backups, to be used for recovery in the event of data corruption, hard disk drive failure, or malware infection. It replaces NTBackup, which has been part of Windows since Windows NT 3.51. Unlike its predecessor, it supports CDs, DVDs, and Blu-rays discs as backup media.

Backup and Restore offers file and folder backup in all editions of Windows. But its full set of features are only available on high-end editions of Windows, i.e., the Professional, Business, Enterprise, and Ultimate editions.

Microsoft deprecated Backup and Restore in Windows 8.0, recommending to use the File History app for file-based backup and a third-party solution for system imaging. Despite its deprecation, however, it is part of all versions of Windows released thereafter.

The Windows Server counterpart of Backup and Restore is called Windows Server Backup.
