Yes! Parity files. This is the solution for dealing with loss on Usenet and will effectively lengthen the life of DVD media by providing redundant information that allows for full recovery of data on degredated DVDs. So maybe you will have to spend 10% of your storage space on redundant data, but it sounds like an excellent fit in your situation.
SmartPar is a good lightweight (and I believe Freeware) program to generate parity files.

It will be cheaper. I can pass on granularity.
