Based on Jason's advice to my earlier query, we purchased one of the
DDS-2 versions of this drive (Archive 4586NP)(and a 12 tape cartridge)
from corpsys.com. We now have tar calling a script that switches tapes
(although the person here who did it found some bugs in tar in the
meantime - NetBSD should look into updating their tar to the latest
BTW). It seems to work quite nicely - about 500KB/sec average over a 5
hour backup of about 10GB with no user intervention.
Just the other day I saw that www.onsale.com had these for sale by
auction. Someone here bought two of them for $470 each (we had paid
$1000 for the first) and the 12 tape cartridge for about $40 or so. I
just looked and they have another batch of them for sale.
If anyone is interested in the tape changing scripts, I can learn where
they are and make them available by ftp.
