Researchers at the School of International Relations and Pacific Studies and the San Diego Supercomputer Center estimate that the total is equivalent to a 5.6-billion-mile-high stack of books stretching from Earth to Neptune and back to Earth, repeated about 20 times. By 2024, business servers worldwide will annually process the digital equivalent of a stack of books extending more than 4.37 light-years to Alpha Centauri, the scientists say. The report, titled 'How Much Information?: 2010 Report on Enterprise Server Information,' was released at the SNW conference last month. Roger Bohn, one of the report's co-authors, compared the world's servers to the underwater portion of an iceberg 'that runs the world that we see... Most of this information is incredibly transient: it is created, used and discarded in a few seconds without ever being seen by a person,' said Bohn."
