One thing that was bugging me a bit lately was that every hour timemachine would run, and would crunch a bunch of data, the cpu would run for a bit, heat up my laptop and mildly annoy me. Mildly because it's better than having a drive crash and losing data (again), but still it was distracting.
I started to look at the timemachine icon to see how much data it was backing up, and it was always just shy of 50 mb. Every hour, 50 mb... I'm not doing anything locally, so by putting 2 + 2 I figured out that it was firefox's cache that was being backed up.
I found an interesting post about what things Ryan Block doesn't back up. I'm going to start with just the cache directories for now. As things grow, I might add more, but I'm okay with backing up too much rather than not enough at this point.
