While working with another package, I stumbled across a relatively new program for Linux called DVDisaster. What it does, effectively, is add ECC information to DVD images so that if you have media errors at some later date, you can run it again and reconstruct the original image.

I’ve checked it out and run my own tests, and it seems to be a good deal for what it does. For right now, I’m using it to augment my present data backup policy: two copies burned on DVD and stored at different locations. It seems to me that it’s cheap protection against minor media dropouts.
