Well, our website doesn't change that often so I was thinking about using rsync.

I guess for two things.  Each might need a seperate solution.

1. Network outage between us and Verizon. (happend twice w/in a year already)
2. DR - Fire in our building and our server room goes up in smoke. (we
do offsite nightly backups).


For:
1. the best solution might be a second link through a different company.
2. ??? might be setting something up with verizon to reroute the IP.
