Having priced media at CompUSA last night, I'm comming around.
If those prices are typical, having 10 DAT tapes versus 12 TR5's
already pays for the difference for a simple DAT drive.

Since I'm likely to be sitting next to the machine doing the
backup, programming away, or massaging data, I tend to shun the
auto-changer. Especially if I mostly do incremental backups. Even full
backups, and even if the 70GB became close to full, it ought to fit on
3 or 4 12/24GB tapes. If we achieve growth to the extent where this
becomes painful, then I don't think we'll sweat the amount spent on the
first drive.

With just two of us on the payroll, and the primary address
book duplicated in a number of Palm's, that doesn't sound as scary as
you might think. Of course, we do hope that will change. Also, since
I proprosed regular incremental backups that were all increments from
the last full backup, rather than just changes from the last
incremental, the full backup would have to fail to keep me from
getting back to fairly recent.

That would be me. More scary is the PHB (the other paid
employee deciding to do something on his own.
Thanks for the insights.
