Hello Kyle,
The short answer is AWS and other cloud services are Ideal for backing up
many TB of media like video.  Netflix started their hosting in AWS for
instance. A few questions:

   1. When you say you have 200TB that you would like to digitize are these
   analog tapes to be digitized and you need a destination or you actually
   have 200TB of files.
   2. If it is the latter where does the media sit right now?
   3. If it is the former do you have a digitization workflow defined yet?
   4. Are you wanting to have quick access to this media say for
   scholarship or reuse or is it just about having back ups?


With Regards,
