Subject: Replication/Synchronization across servers not on the same network

I'm facing an upcoming project that will have the following scenario and
I'm trying to figure out what the best solution would be:

2 servers in separate locations with the same website actively operating
on both servers.  The website allows for uploads of files and images to
the server.  The files on each server need to be updated (at least
daily, if not faster) from the files on the other server that have been
changed.  The site structure cannot be changed and we can't just use one
of the servers as the file server.  Both actually have to have copies of
the files.

My thoughts are as follows and any other suggestions or pros and cons on
each option would be great.

1. Use CFFTP to move new files from the server that the change is made
on to the other server at the time the change is made. In my mind the
downsides are the extra network traffic at possible peak times and how
to handle files if the upload to the first server works but for some
reason the upload to server 2 fails.

2. Use an FTP program that will allow scheduling and synchronization to
do the synchronization nightly.  This would take the load off of CF and
run it at a time when the traffic should be lower.  It should also be
easy to tell if it fails and work from there.

Please let me know your thoughts, especially if you have experience in
this area.
