BITS is nothing like rsync. The purpose of BITS is to allow low-priority downloads/uploads to progress without impacting the real-time network traffic on the machine. (The classic use being to download Windows Updates without annoying the user by slowing down their web surfing.)
Rsync exists to synchronize folders between machines.
Thanks for the correction. I have never used BITS, but at one time I thought the description of "intelligently transfer files over the network" sounded familiar.
