In particular, the question I'm trying to answer is, "how do we calculate the difference between two encrypted blobs?". Do GPG/tar provide random access within an archive? Or does Duplicity just diff whatever comes out of the stream? Etc.
Since we can't send the encryption key to the server, does the entire backup history need to be downloaded during this process?
