I'm trying to trim down the size of my SD backup a bit. One thing I ignored is my IMAP mail cache:

/Users/xxx/Library/Mail/IMAP-xxx@yyy.com/

There is really no need to include it, it gets big and if I have to restore, all my mail is on the IMAP server anyway.

Looking for some other things to exclude. I know the default backup all script already excludes quite a few OS related files, but I'm thinking perhaps there are some more that could easily be excluded and want to hear comments or warnings from you guys about some or suggestions for others:

~/Library/Caches/
/Library/Caches/
/System/Library/Caches

What about temp files and particularly spotlight files? I'd like to make sure they are excluded as well. where are they?

Anything else you can think of of significant size?
