I'm currently backing up three 2003 Servers to a share on a backup Server (running 2003) with the NTbackup tool. I am considering upgrading the backup server to Windows 2012 and am interested in the De-duplication feature. The server's do a full backup every night with each server writing its own bkf file on the backup server with each backup being appended to the existing bkf file.
I am curious as to whether the de-duplication feature would be able to bring about a storage saving for this scenario?
