In a shop with a goodly amount of money, based upon my experience I'd go for
tiered tape technologies: something like a 3590 library for primary tape storage
pools, where optimal start-stop performance and speed is important; and some
kind of streaming tape library technology for non-collocated copy storage pools
and cheaper, more capacious, but reliable offsite tapes which get banged around
a lot.
