Data Preservation and How Ancient Egypt Got It Right 313

storagedude writes to tell us that a storage geek has an interesting article on why ancient Egyptians were better than us at data preservation — and what we need to do to get caught up. "After rocks, the human race moved on to writing on animal skins and papyrus, which were faster at recording but didn't last nearly as long. Paper and printing presses were even faster, but also deteriorated more quickly. Starting to see a pattern? And now we have digital records, which might last a decade before becoming obsolete. Recording and handing down history thus becomes an increasingly daunting task, as each generation of media must be migrated to the next at a faster and faster rate, or we risk losing vital records."

    As recording things became easier, more things were recorded. At some point we began recording things that no-one will ever care about, and now keep things recorded that we didn't even know were recorded (care to see my router logs?). The less significant something is, the less we need to worry about preserving it. Of course, there are things worth preserving, but most of it just isn't.

    Seriously what a piece of complete and utter rubbish. From Ancient Egypt we have an extremely limited set of information because stone tablets crack and they aren't exactly the most portable things in the world. Go through to the Romans and paper, and the Chinese and you are seeing massively more information become available down the centuries. Zoom forwards into the 14th Century and we have a massively detailed view of what life was like which becomes more and more detailed as time goes by. The key here is detail, the amount of information in Ancient Egypt was huge, probably comparable to today, but the amount that was etched onto pyramids was tiny and quite a lot of that didn't survive anyway.

    The key things that future historians need are prime sources and one thing that the internet is massively impressive at is the duplication of information and the avoidance of redundancy. Stone is rubbish for this, no-one bothers making copies so you lose the original and you lose everything.

    Printing introduced simpler copies which meant that the information was more likely to survive down the years. With modern digital technology this increases still further. It is ridiculous to claim that digitally we won't have more information about the major events and people of today which is available in 400 years. We will have more CRAP available in 400 years (blogs, twitter, Slashdot) than any generation of historians have had to wade through.

    Digital technology makes accurate duplication simple and that is the most powerful way to make sure information survives. Wikileaks is the embodiment of that view. The issue is that there is now SO MUCH CRAP that the issue for future historians will be in wading through all of the blog posts of "Obama is a Muslim" to find out that in fact he wasn't.

    A rubbish supposition which is massively undermined by every time there is a censorship case the plea to "mirror the information".

    Some information will be lost but the amount that will survive is miles higher than the amount of information that survived from Ancient Egypt.

Historically important audio recordings from the 60s and 70s are badly decayed ("For those unfamiliar with the Nixon tapes, other than telephone conversations, they are extremely difficult to hear (in analog versions, and with the available equipment, it would take approximately 15 hours to transcribe one hour of Nixon's conversations)" [hnn.us], and tapes of Creighton Abrams running the Vietnam War were barely playable).

    This is another case of only seeing part of the problem. Data preservation is easy. The problem is, we generate massive amounts of data. Data doesn't have an expiration date. It doesn't automatically categorize itself, know its own relevance, or volunteer itself for tasks. See, the vast majority of "data" floating around can be safely discarded. Do you really need an ethernet sniff log of everything you've done on the internet over the past ten years? The government might want a copy, but chances are pretty good its just as useless to them as you. How about those four (broken) copies of that mp3 you downloaded from Shareaza? Or outdated installers of software? Is there a reason to keep around those Netware 3.12 floppies (besides impressing other old farts)?

    The problem isn't preserving data, it's knowing when to let it go. We have many, many, many methods of data preservation. We are drowning in information. The internet is generating petabytes worth of data every day, and only the smallest fraction of that really has any reuse value. And most of that, in six months, or a few years, probably not. What we need is better methods of sorting data, and ways to expire data safely.

    Also, we also need control over our data. Corporations have been trying to take that away now for years. You don't need a copy of our software that can run on any computer, we're going to mung it up so it only runs on one computer, and if you have to reinstall the operating system or change the video card or anything else, that copy will cease to work. An irony, really -- because I know plenty of people that love playing old video games whose manufacturers long ago gave up on, but won't release the copyright for. Fifty years from now, I doubt a single copy of the game will still exist -- the concept, maybe. But it will have died and yet someone will still own the copyright and think money could be made off it. When we buy a chunk of data, we need to be able to control it, not just use it in some narrowly-defined way. Because otherwise, what's the point of data preservation in the first place? To stockpile more useless data that -- even worse, holding onto could be a liability to you?

      2. The internet is designed for copying.

  • There are a number of problems, some of which are obvious like longevity of media. A bigger problem is the hardware to access the media. And even bigger, is the format of the data.

    OK, under proper conditions a properly made CD or DVD will last nearly forever. But it requires some really fancy optics and a solid state laser diode to read it. And a DVD requires a microprocessor - can't get away with some simple logic chips like you can with a CD. And the encoding of the data itself is complicated - proba

    • Today in Europe would a set of construction plans from 1920 make any sense at all?

      The metric system was introduced in the 18th century.

      And in 100 years the likelyhood that either ASCII or Unicode will survive is very remote.

      I think, 100 years from now some people will still remember the order of the alphabet, and some will even know what binary digits are. Put those two things together - you got ASCII. Add some more offsets - you got Unicode.

      Alan Turing cracked Enigma 70 years ago. I'm pretty confident someone will crack ASCII or Unicode in 100 years - if it will be abandoned.

    • Don't be ridiculous.

      Wrong. CD-Rs and DVD-Rs have been proven to have very short lifespans, since they are merely dye altered with a low-power laser. Pressed CDs and DVDs, OTOH, have much longer lifespans (probably indefinite if stored properly, and if manufactured right so they don't get "DVD rot" or "CD rot" as some have. But while most movies are made on pressed DVDs, how much data is stored on them? Not much, only propriet

    The whole article is ridiculous. The first sentence is

    My wife and I were in New York's Central Park last fall when we saw a nearly 4,000-year-old Egyptian obelisk that has been remarkably well preserved, with hieroglyphs that were clearly legible

    What is remarkable about that? If you want to put a ancient Egypt rock in the Central Park, do you use a shattered obelisk where you can't read anything or do you take the nice one?

    And how ignorant is the author to ignore all the broken, lost and otherwise destroyed rocks that didn't survive?

    If you want to write an article about the lack of metadata standards and your perceived lack of long-term storage options, fine, but don't built it around your wifes spontaneous epiphanies.

  • This is why I've been chiseling reddit headlines into the concrete in my driveway. And the neighbors call me crazy!!!

  • How many rocks do I need to chisel to keep a copy of the current Wikipedia? Are there even enough mountains in Egypt for the top 10,000 articles?

    I think we'll manage to keep enough of the important data by migrating to newer media over time. Besides, it's not like we have any better options.

  • Is a 4GB Bigfoot (5-1/4") Hard Disk the same as a stone obelisk?

    Or should i mod my CD writer to write on stone? May need a little bigger PSU for that but upgrades are fun.....

    Seriously tho, the older the better for long-term storage. Can apply this large scale or small...stone tablets or old disks.

      Yes.

      Let the Iliad represent a typical ancient Greek text, occupying 24 scrolls. In a modern edition it occupies 1,589,248 bytes in Beta Code (= ASCII transliteration of ancient Greek), or 66,219 bytes per "book" (scroll).

      Ptolemy II set a goal of half a million scrolls for the library. This is probably a pretty conservative estimate of the library's size at its height. However, let us work with conservative estimates. This gives us a ballpark figure of 33.1 billion bytes, or 30.8 gigabytes, for the Library o
