I can't speak for everyone but I hope you keep this discussion on the list. If
it does happen to go off-line, I would greatly appreciate a copy of the final
thoughts.
There was a thread that went around a couple of months ago with price
comparisons for all of these different media types (including hardware and
media) but I'm sure it's already outdated. The VXA drive from Ecrix looked
like it had potential for a smaller setup due to it's price of drives and
media. The media also looks very reliable according to the material on their
web site. I am currently using DLT and it gets a little expensive to stay as
redundant as I would like to be. I've noticed that Ecrix is coming out with
larger tape libraries, Does anyone think that will make it a more viable
solution or is AIT still the way to go?
thanks,
Tim
