Backup files for Adobe Bridge?

I'm using Bridge to put metadata keywords with all my photos, but can't find
a good list of everything I need to back up to be completely safe. I want to
make sure that my original keyword list is saved, as well as the colour and
word additions to the photos. Can anyone identify the file names and their
locations to backup?
