Not sure if this has been posted before, but after upgrading to Lion, I noticed that my hourly Time Machine backups were saving 5-7GB every hour (and I don't do that much work on it).
Looks like Lion is storing my GMAIL email locally and TimeMachine is backing up the database(s) every time it runs. The files were located at ~/Library/Mail/V2 , and I excluded the two gmail accounts (1 google app) that I have set up on the Mac.
The easiest way that I found to do this was to use the Finder to get to the ~/Library/Mail/ folder and move the V2 folder onto the sidebar - then I could go into the Time Machine Prefs, add the exclusion, and click the icon in the sidebar to select the two mailbox folders under V2. For some reason (probably safety), I couldn't get to the ~/Library/Mail folder easily in the Time Machine Exclusion selection box....
Anyway, now my backups are like 150K - 2MB/hour which makes much more sense...
Hope this helps...
