sun sells fugitsu gcr tape drives that work fairly well.. on a lightly
loaded system, i've seen them back up an entire eagle (~500mb) in 30 minutes.
it takes 4 tapes or so, however, even at 6250 bpi. this definitely is not
fastest (disk to disk probably is), but is sure straightforward.
dump was the utility that did this, btw.
