In addition to the atomicity advantage, rsync allows compression of the
data on the fly. While you can also pass the -C flag to scp, I've found
that the high compressibility of WAL files means that rsync -z is noticeably
faster than scp -C (not that I would use the latter due to the partial file
issue).
