Using rsync to synchronize

Hello,
  I have been using rsync to backup our primary data stores. It works
fine. Here are the options I use for doing that:

rsync --recursive --links --times --dirs --stats --delete \
  --itemize-changes --quiet --exclude-from=exclude-filename \
  /data-store1/ /data-store2/

  Recently I have had the need to actually synchronize the files
between two data stores. That is, whichever data store has the newest
timestamp updates the other data store.
  What are some recommended ways for using rsync to synchronize two
data stores?
