I haven't used duplicity, but I don't see why this behavior would be so 
ingrained in the architecture that it couldn't be changed via a 
configuration or minor patch to the code. (Even if a patch is necessary, 
it should be far less work than inventing a whole new backup tool.)

Try Rsyncrypto:

I believe it meets all of your criteria. If I remember correctly, it 
works with a standard rsync server on the remote end.

(I haven't tried out Rsyncrypto in several years, and it was in a rough 
state when I looked at it, but it appears to have been under active 
development since then.)
