I can think of two obvious solutions.

One is to use rsync to keep things in sync.  Obvious advantage is that  
it is simple to setup.

The other one is to use CVS or some other revision control system.   
You may wish to block access to CVS directories (in case of CVS) it  
will create in httpd.conf.  It is more complicated to setup, but if  
you already use CVS or some other revision control system to manage  
those 100 MB of HTML than you already have everything in place.  Just  
do "cvs co whatever-you-call-it" to copy current version out of  
repository.  You are using some kind of revision control system to  
manage those 100 MB of HTML?  Right?

Either will transfer only the updated files.
