This may be very nice for the high end, but getting "geographic diversity"
means you have to get space in a colo of some sort (unless you're a big enough
site that you have another building of your own at least a mile or two away),
and bandwidth between the two sites.

Somehow, I don't see this anytime soon for the home user, the SOHO user, or the
small company that has 7-8 internal servers and a T-1.

Remember that for this to work, the bandwidth and off-site storage has to be
available at a cost the user can afford. Remember that a lot of people aren't
too happy with the current price point for cable or DSL access - and those
price points are set with a high overcommital of bandwidth. If everybody
starts trying to do backups over the network, the provider will have to build
out more capacity, and raise the price to cover it.

Yes, we're looking at offsite disk mirroring as a backup solution. But we're
lucky that we have a large open space in a switch room some 3 miles from the
data center and dark fiber from here to there. But it's STILL going to be a
big chunk of change. I dread to think what it would cost per month if we had to
pay for the space and bandwidth.
