Cuneiforms on baked clay tablets have greater bandwidth than engraving on granite. But they are not quite as permanent a backup medium. As for privacy, forget it. Most encryption schemes have been broken. That's a problem with encoding your ideas into a system of fixed symbols, whether alphabetic or some other system of glyphs. If you want privacy as well as long-term storage, you might want to consider cave painting. People are still trying to figure out what those mean after 30,000 years, even though the public key is in plain sight. Pictures have that advantage over words. Think of some of the GUI interfaces that try to get by without using words on menu items, or some of the universal signs you might see marking the parts on the dashboard of your car. They make for a great encryption system -- tough to crack. Cave paintings are like back to the future, so for present storage needs you might consider going forward to the past. John Gorentz
