"If you want to do a two-way synchronization with
rsync, you'll need to run it twice. It isn't difficult to run rsync
twice, and doing it that way allows you to automate different
synchronization options for one direction than for the other, which
can sometimes come in handy. Nevertheless unison is so much easier
for straightforward synchronization tasks that I've switched from
rsync to unison when it comes to synchronizing my home directory
across machines.
Here's the scoop on how to use unison. It is most powerful when
you use it interactively, because this gives you a chance to decide
how to resolve conflicts when both the source and destination files
have changed. However, you don't have to use it interactively for
it to be useful. In my case, I have a personal version of the
following shell script in my /etc/cron.daily directory on each of
my servers. This script synchronizes the home directory from client
to the servers."
