An HP SCSI DAT drive.
I like it lots. :-)
I don't think you'd have much to complain about with the Iomega
though. My only beef with backups in general is that I want 'em big enough
to do a full backup and preferably some incrementals without having to
change the tape. With the size of Hard Drives these days, its tough to do
that with a tape that only holds 400 MB raw (that 800 MB stuff is
fantasy--you'll never see that on a tape unless the data is highly
compressable, which is unlikely. Figure on about 1.5x compresson on
tape--so that 400 MB will get aroun 600 MB on it).
DAT, on the other hand, while it holds as much as 4 GB raw
(DDS2--mine's just DDS which holds 2 GB raw), is much more expensive for the
drive, but cheaper on the tapes. My drive cost about $700+ when I got it
new a couple years ago (I got a great deal--but I think you can buy these
new for around this price today), but the tapes can be had for $8 a piece
(compare that to $30 for a Travan tape for your Iomega). Since I rotate
tapes and keep archives up to a year beforehand, tape price is a
not-to-be-ignored factor, making the cost of the drive somewhat moderated.
