A bit late, but here’s an update of the Time Machine exclusion list for Snow Leopard.Here’s the full list of the excluded paths:
The contents of these paths are excluded, but the directories themselves are preserved as they are required for a successful restore. Remains the same as in Leopard.
/Volumes /Network /automount /.vol /tmp /cores /private/tmp /private/Network /private/tftpboot /private/var/automount /private/var/run /private/var/tmp /private/var/vm /private/var/db/dhcpclient /private/var/db/fseventsd /Library/Caches /Library/Logs /System/Library/Caches /System/Library/Extensions/Caches
These folders are excluded pre 10.5.something [Does anyone know when these came about?]
/private/var/log /private/var/folders /private/var/log/apache2 /private/var/log/cups /private/var/log/fax /private/var/log/ppp /private/var/log/sa /private/var/log/samba /private/var/log/uucp /private/var/spool
These directories and their contents are excluded completely. Remains the same as in Leopard.
/.Spotlight-V100 /.Trashes /.fseventsd /.hotfiles.btree /Backups.backupdb /Desktop DB /Desktop DF /Network/Servers /Previous Systems /Users/Shared/SC Info /Users/Guest /dev /home /net /private/var/db/Spotlight /private/var/db/Spotlight-V100
User Paths Excluded
These directories and their contents are excluded per-user. The path is relative to the user’s home folder.

These directories are not themselves excluded, but the files in them are. The directories will be recreated on restore. Remains the same as in Leopard.
