I was wondering what was using up space on my TM drive so I've put a short perl script together that compares two time machine backups so you can see what's changed between one and the next.
You need to run it from the Terminal. Here's an example session.
The first column indicates the type of change
n - New in the second selected version
d - Deleted in the second selected version
c - Changed between the first and second selected versions.
It's not tested much but should work ok, it doesn't make any changes to your TM drive. If you get errors about 'permission denied' then you need to run it as root as your user can't see into a directory.
You can download it here if you want to give it a go.
Any feedback or suggestions for improvements welcome.
Edit: Just a note to say if an entire directory has been added or removed you'll only see the entry for the directory not the individual files inside it. eg:
n - /PlanetExpress/iTunes/iTunes Music/Compilations/A City Centre Offices Sampler/
