Aside: I have two questions about rdiff -- in the interest of netiquette and such, I'll post them in separate emails.
I've googled enough to find out that rdiff at least in some circumstances uses rsync to minimize communication bandwidth. My question is this: if rdiff-backup is backing up to a disk (internal or external) on the machine being backed up, does it continue to use rsync? I presume / hope not, as I don't see any advantage to that.

Writing is often meant for others to read and understand (legal documents excepted?) -- make it easier for your reader by various means, including liberal use of whitespace (short paragraphs, separated by whitespace / blank lines) and minimal use of (obscure?) jargon, abbreviations, acronyms, and references. If someone has already responded to a question, decide whether any response you add will be helpful or not ... A picture is worth a thousand words. A video (or "audio"): not so much -- divide by 10 for each minute of video (or audio) or create a transcript and edit it to 10% of the original. A speaker who uses ahhs, ums, or such may have a real physical or mental disability, or may be showing disrespect for his listeners by not properly preparing in advance and thinking before speaking. (Remember Cicero who did not have enough time to write a short missive.) (That speaker might have been "trained" to do this by being interrupted often if he pauses.) A radio (or TV) station which broadcasts speakers with high pitched voices (or very low pitched / gravelly voices) (which older people might not be able to hear properly) disrespects its listeners. Likewise if it broadcasts extraneous or disturbing sounds (like gunfire or crying), or broadcasts speakers using their native language (with or without an overdubbed translation). A person who writes a sig this long probably has issues and disrespects (and offends) a large number of readers. ;-) '
