--- Comment #1 from Matthias <mail at matthiasbock.net> ---
This is probably not so easy, since the keys which are used for encryption
during an SSH session are negotiated in advance to it, are unique for the
session (used only once) and get discarded when the session terminates.
Up to my knowledge, rsync does not get in "contact" with the SSH layer, which
it is making use of, meaning the session keys are not trivially accessible.

You might want to consider using losetup for transparent encryption, e.g.

 losetup /dev/loop1 backup.file -e aes512
