There's a related issue we discussed a while ago: One thing that's different between rsync and naive use of librsync (as done by rdiff and, I think, rdiff-backup) is that the latter doesn't have a strong full-size integrity check. With librsync's default 4-byte checksums, using a small block size on a large file makes the probability of silent corruption disturbingly non-negligible.
