For the machines being backed up over the internet, I'd recommend
setting IncrLevels to 1, 2, 3, 4, 5, 6 in order to minimize your
bandwidth usage.

I have used the setup Les describes, with IncrLevels as stated above,
successfully in 2 scenarios.  One was a business that had an office in
the USA and the UK, and one is in use at my home and my parents' home.
