I "think" i work for a leading edge tech company, and we use tapes, and have
a autotape hopper that holds a bunch of tapes, and we recently upgraded to a
bigger and better tape device that works off a virtual tape (bunch of
disks). I dont think we would use dvd for a number of reasons chiefly
reliability and security. Cost would be pretty low on the pole. We also
have terrabytes to backup.
I was looking at using dvd for my own personal backups, at work and at home.
I ran some tests on those new dual layer dvd's and was very disappointed. I
would get a few errors at the conclusion of an 8.5gb or so dvd write. I was
just using the latest nero (not a dedicated backup program) and depending on
what burner I used (pioneer A08, BenQ 1655, 1620). What is strange is
that more often than not, it was a false error. I was able do copy the zip
or zips off the dvd backup and test them and they would be fine. The
reliability is not there. Plus one would not normally backup zips and stuff
that if a sector was damaged, one of the files might be extractable. A real
backup program would do a better job.

As ron mentioned, you could get a bunch of big drives for that price.
Question: What if the data you were backing up was worth, say $10 million
in lost manhours? How comfortable would you feel with an under 1k package?
