Go to office Depot or Staples or whatever the local office supply store is, buy out their entire stock of paper and number 2 pencils. Proceed to copy down bit for bit the content from your hard drive. If you write really small, you might be able to fit it in under $500 worth of supplies.
For even greater redundancy, you can use clay and chisels, but thats just too time consuming for the average user.
