DocJay, the Vista Backup team has a couple blog posts you might find
interesting.
This one explains why incremental backups are larger than expected:

This one is our general FAQ based largely on questions I've seen in the
newsgroups:

I'm hearing a lot of people complain about the size of their incremental
backups. Something on your computer is changing those files, even if you
aren't personally. The first blog post above gives some possible
culprits--antivirus software, for example.
To everyone else who has responded--this is really great, actionable
feedback.
