Windows Server Backup

Windows Server Backup (WSB) is a feature that provides backup and recovery options for Windows server environments.

Administrators can use Windows Server Backup to back up a full server, the system state, selected storage volumes or specific files or folders, as long as the data volume is less than 2 terabytes.

New functionality introduced in Windows Server 2008 R2 includes automatic usage of disk space, smaller and faster incremental backups (which Microsoft calls block-level backups), the ability to restore Windows to different hardware and simpler recovery options if a system volume in a server is lost.

First introduced in Windows Server 2008, Windows Server Backup replaced the Ntbackup feature in earlier Windows Server operating systems.
