Data Written With "Superman Memory Crystal" Could Last Billions of Years (computerworld.com)
Lucas123 writes: Researchers have demonstrated a method of femtosecond laser writing in self-assembled crystaline nanostructures that can withstand temperatures of up to 1,000 degree Celsius and last indefinitely at room temperature. The storage method enables up to 360TB of capacity on a single disc. Data is written to a file comprised of three layers of nano-structured dots separated by five micrometres. The technology was first demonstrated in 2013 when a 300 kilobit digital copy of a text file was successfully recorded in 5D digital data by femtosecond laser writing. Major documents from human history, such as the Universal Declaration of Human Rights (UDHR), Newton's Opticks, Magna Carta and Kings James Bible, have been saved as digital copies that could survive the human race. Coined as the 'Superman memory crystal', as the glass memory has been compared to the "memory crystals" used in the Superman films, the data is recorded via self-assembled nanostructures created in fused quartz.

So long as they called the directory: Documents we humans chose to ignore.

We don't need to store data indefinitely, we just need to keep Slashdot up. Any lost information will be duplicated here eventually.
It's considered cheating; but you can also ensure that the backups always outlast the users by 'retiring' any user whose backup media are starting to show signs of flakiness. The side benefit is the steep reduction in the number of people asking you to pull something from backups for them.
