It seems that Windows Backup Server on 2012 does not backup to tape, only to block storage devices.
Anyone know if there is a way of backing up to tape on server 2012, just like the old ntbackup used to do? We want it in the same .bks format as ntbackup because it will be restored to a disaster recovery site using ntbackup.
Thanks
There is no built-in functionality to support backup to tape (and hasn't been starting with Windows Server 2008). You'll need to look at third-party software (of which there are plenty of commercial and some free/open source offerings) for that functionality.
NTBackup writes ".BKF" files, which are file-based representations of the Microsoft Tape Format. I know that Symantec Backup Exec has, historically, supported creating tapes in Microsoft Tape Format but, given that you won't be restoring the backups with NTBackup (seeing as how there isn't a Windows Server 2012 version of NTBackup) I'm not sure that Microsoft Tape Format compatibility is really all that important.
