Prof. George Church (Harvard) is developing methods of storing digital data in DNA. He has stored up to 700 TB per gram so far. He stored his own biology textbook in DNA and made 70 billion copies. (He described this as "the largest printing" of a textbook in history.) Under proper storage conditions DNA will last for hundreds of thousands to millions of years. With multiple copies and file compare routines you can easily detect and exclude corrupted copies. You could fit all of the data in the world into ~100 g of DNA.
