Not just over the wire, according by your webpage, but even backup server can't decrypt it. Excellent. But how can you do that with a secure (hence chained) encryption mode while maintaining the communication efficiency of rsync? The only way I see is to keep the backup data in numerous separately encrypted fragments (inconvenient) and have the sender transmit the encrypted block hashes (communication cost) or keep them between sessions (stateful). It's also susceptible to traffic analysis, but that's probably not a major concern. They had the same problem with gzipped files, BTW, and proposed solutions were to either gunzip+gzip on the fly (but then the resulting gz file may differ from the original even though its content is identical) or to use a patched gzip which occasionally resets the compression state. Neither is applicable in this case.
