For server operating systems, Microsoft has replaced NTBackup with Windows Server Backup beginning with Windows Server 2008, which includes the new wbadmin command.[2] This new backup application, wbadmin, no longer supports tape drives, which means that users have to install third-party applications to back up to tape on these new operating systems.
For reading/restoring older backups, Microsoft has made available the NTBackup Restore utility for Windows Vista/Windows Server 2008 [3] and for Windows 7/Windows Server 2008 R2 [4] which can only read BKF files.
When used with tape drives, NTBackup uses the Microsoft Tape Format (MTF),[5] which is also used by BackupAssist and Backup Exec and is compatible with BKF.[6]
