You assume I know the implementation details, which is not the case.
I think I follow what you're saying. I had just wanted to find a way to
establish a rsync-like mirror that was encrypted on the remote storage
host. I guess that's not possible without doing full backups every time?

Does anyone have any advice of other software that allows
encrypted mirroring (possibly without doing full backups
every time)?
Thank you for your responses. I appreciate them AND the software.
