Consider generating them on demand only.  The CPU and I/O savings will 
probaly make up for the havig to wait for the graph to generate :-).  I'm 
doing that with hundreds of thousands of RRD files now.  I also have a 60 
second cache, so if multiple parties are hitting the same graph parameters 
at the same time (responding to some event) the servers doesn't fall over 
on their arses.
