We had a presentation from the company LiveVault[.com], which takes the
fascinating approach of using an NT OS I/O system API to continuously capture
and save all updated bytes, in real time, allowing you to restore to any
moment in time.  A very different approach, which may solve backup problems
that traditional "batch" backup schemes can't.  If anyone out there has had
experience with them, I'd be interested in hearing about the realities of
using such a product.
