Very Long-Term Backup
3rd March 2023
This problem of long-term digital storage seemed a crucial hurdle for any civilization trying to act generationally. How could a society think in terms of centuries unless there was a reliable way to transmit and store its knowledge over centuries? This puzzle was the focus of a conference hosted by Long Now in 01998, dedicated to technical solutions for Managing Digital Continuity. At this meeting Brewster Kahle of the Internet Archive suggested a new technology developed by Los Alamos labs, and commercialized by Norsam Technologies, as a solution for long term digital storage. Norsam promised to micro-etch 350,000 pages of information onto a 3-inch nickel disk with an estimated lifespan of 2,000 -10,000 years.
