Long Term Storage

In my garage I have a filing cabinet with one drawer containing all the important papers from my undergraduate courses.  In the second drawer I have everything from graduate school.  These are all papers and they are approaching twenty years of age.  I don’t think anyone will ever care to look at them.  It’s just that they took so much of my time to create.  I can’t bear to throw them away.  I am certain no one will ever digitize them.

According to this article, a famous person like John Steinbeck, author of The Grapes of Wrath, has thousands of pages that will never be digitized.  Steinbeck’s work isn’t the only thing lacking digital preservation.  Of the 132 million objects held in the Library of Congress, only 10% will probably ever be digitized.

For the most part I am ahead of the game.  All the important papers that I wrote in college are in digital format.  We had a mini-mainframe with an ASCII text editor.  All my papers fit on one (state of the art at the time) 3.5 inch floppy.  I still have that floppy.  I have copied it over to a CD for long term storage.

I went to graduate school immediately after undergrad.  It was during this time that I really learned to use a PC to publish.  All my writing was done using WordPerfect 4.  I used Ventura Publisher for all my publications and CorelDraw 2 (that’s right… TWO) for all the graphics.  I also started to back everything up to a Colorado 120 MB tape drive.  I still have all those tapes too.  In the box with the tapes I kept an external drive with an eight bit card.  Hopefully, if I ever want to retrieve any of that information, I will have a computer with an eight bit slot. 

That equipment brought me up to the age web publishing.  Since about 1995 I have had access to a CD burner.  All of my archives have been to optical disks.  Now I have thousands of CDs and DVDs from weekly backups.  Last week’s backup filled ten DVDs.

Over the weekend I was talking to my wife about video of the kids.  We have about 100 VHS tapes that we would like to keep, but don’t want to bother with digitizing.  I think my dad bought a VHS to DVD recorder last year.  I could use that to get all those tapes into digital format.  They would take up a lot less space and I wouldn’t be stuck with a VHS player for the rest of my life.

I try to keep my digital archives in a format that is useful to me as time goes on.  For instance, I have used Eudora for my email since 1992.  I have fifteen years of email that I can search fairly easily.  Just last weekend I needed a username and password that was emailed to me several years ago (I didn’t know what year).  I found the message from March of 2004 in about a minute.

Backups are not only important for the occasional hard drive crash.  They are also important for long-term storage of information.  Keeping all these things organized is important.  I keep a database that has a list of all the archives I have.  I number all my disks and record the disk number with the contents of the disk in the database.  Every time I burn a new archive set, the first thing on the disk is the database of all the previous archives.  So I can pull out last week’s archive and get a list of all my archived disks with their contents.  I keep all the disks in binders.  I use a Sharpie to write the disk number range on the spine of each binder.  That makes it easy to find old information.

In fifty years it will be interesting to see how much of this information I can still access.  As long as I have a DVD drive, I will be safe.  I suppose the last DVD I burn will have to go into a box with an external DVD drive.

    Alvin, I do the same with my dvd videos. I have 3 young children who already have about 60 hours of burned dvds. My question to you is, has there been any studies to show the reliability on dvds regarding how long they will last. I keep mine in a dvd leather binder in my fire proof (or so they say) safe. In 20, 30 or even 50 years, will the structure of the dvd still be in decent enough shape to take data off of it and share or store it onto another device. The only thing that I see replacing dvds in the near future are memory sticks that will hold 100′s of gigabytes one day and that you just have a usb slot on your television or viewing device that you plug into to view content. What are your thoughts please?

    The best you can do is keep your disks cool and dry. I have read different studies stating data longevity of anywhere from 20 to 100 years. I have many CDs that are ten years old and all the ones I have tried still work.

    I don’t keep all my eggs in one basket. I have external hard drives that I use to backup my important data too. The total disk space needed to backup every important piece of information I have created/received in the last ten years is less than 100 GB. An external hard drive to hold that much data is less than $100. I periodically buy an extra external drive and do a complete backup. Before Christmas I picked up a 160 GB USB drive for $89. I copied everything important to that disk. Then I disconnected it and put it back in the box. It’s still sitting on the bookshelf in my office. The longevity of a hard disk drive is directly related to the number of hours that drive is spinning. Who knows… in the box, that disk may last 50 years.

  3. This problem of data transfer is a large one, to my mind. We have trouble retrieving data from just 10 or 20 years ago (think HS or college papers), so I am not optimistic that data retrieval will be easy in another 10 or 20 years into the future.

    CD’s and DVD’s are only good if they don’t get scratched. The longer you store them, the more you use them, and the more kids you have, the more danger that media is in!

    And if there is a fire where you store the CD’s, DVD’s, external drives, or USB’s, the data could well be lost anyway.

    Do you have anything in a fireproof off-site location like a bank box? To my mind, that is a safe alternative, but not very convenient. I like the idea of uploadable off-site storage, but I am concerned about privacy issues – especially when the government seems to so easily be able to coerce companies into giving out private information!
