Since it is a requirement to preserve the original (compressed) 
files as received, using subversion on the uncompressed data 
would result in doubling the storage requirements (if subversion's 
compression for internal storage was similar to the compression 
of the original data). Needing twice as much storage is not 
attractive, especially since we already have storage limitation 
issues. Do you know of a version control system that would 
work efficiently while preserving the original (compressed) 
files as received?
