backups spanning tapes help

[Brent]

We use a freebsd box that has a old 8mm library drive attached that we use for
backups..my question is these tapes hold 7gigs native or 14 gig compressed
..One i cant seem to get compression going so i was wondering how do you span
tapes using tar ? Unless theres another way to do this 

thank you for your help & Merry Christmas
