OSX 10.6 Time Machine Exclusions

A while back, I had come across an article recommending that one optimize their Time Machine backups by excluding certain system and library folders from backup. The reason of course being that OSX isn't smart enough to exclude certain caches on its own.

People were saying to exclude
~/.Trash
/.Trashes
/Library/Audio
~/Library/Caches
/Library/Caches

Well, I just wanted to let the Internet know that this is unnecessary (under Snow Leopard at least). Apparently you can exclude things without them appearing in the TM Preferences list (like when Parallels has it's "Do Not Back Up With Time Machine" checkbox. You can use this to cut down on the size of your TM exclusions list.
