On DNA. Which apparently can last for 1000's of years!
"Forget hard disks or DVDs. If you want to store vast amounts of information look instead to DNA, the molecule of which genes are made. Scientists in the UK have stored about a megabyte's worth of text, images and speech into a speck of DNA and then retrieved that data back almost faultlessly. They say that a larger-scale version of the technology could provide an extremely dense and long-lived form of digital storage that is particularly well suited to data archiving"
"Half a Million DVDs in Your DNA"
At the storage density achieved, a single gram of DNA would hold 2.2 million gigabits of information, or about what you can store in 468,000 DVDs
