Not only does NASA not have it data backed up, it doesn't even have the 
machines necessary to play a lot of it back.  While the information 
might be historical, it is all obsolete and of little use to current and 
future work.  There was a presentation at the Early Television Museum 
conference 2 years ago about the unsuccessful search for the original 
data recording that would have the Apollo 11 moon walk video.  A single 
Polaroid picture taken of the video monitor on the converter in the 
Australian receiving station shows how much more detail would be on that 
tape if it could be found because the converted pictures had degraded so 
much during the multiple relays from Australia.  As the search began 
about 5 years ago it was noted that the only machine that could play 
back that tape was about to be dismantled and destroyed!  They were able 
to save it just in case that tape could ever be found.
