Backup Media Server BE 2012

Hi

Regarding distarer recovery preparation of the media server itself can please someone provide a link ?

BE 2012 Installed,making a SDR backup of the media server that is stored on a dedup location and making a copy of the backup on tape.If the server is lost what is the procedure of restoring the media server itself ? Do i need the SDR information files offsite as well wehn recovering from the dedup or do i need them only for tape backups ???
