     I'll let everyone know how the 10 GB NTFS partition with 7 GB of
     data on it compresses down to and how long it took to make a backup
     accross a 100 Mbit connection.

   The back-up file ended up being around 5GB. We had 100 mbits (as
   indicated by the switch) between the two systems. The backup took
   about 6 hours. That's less than a 10 mbit transfer rate. I was not
   able to ascertain the bottleneck. CPU usage was below 30%. The hard
   drive lights on both boxen were blinking intermittently.
