There are two conceptualisations of data archaeology, the technical definition and the social science definition.
Data stored in outdated formats like the floppy disk have to be restored to newer formats
Storing data in an off shore server is a good preventive measure against data loss
The Nimbus satellites were second-generation U.S. robotic spacecraft launched between 1964 and 1978 used for meteorological research and development. The spacecraft were designed to serve as stabilized, Earth-oriented platforms for the testing of advanced systems to sense and collect atmospheric science data. Seven Nimbus spacecraft have been launched into near-polar, Sun-synchronous orbits beginning with Nimbus 1 on August 28, 1964. On board the Nimbus satellites are various instrumentation for imaging, sounding, and other studies in different spectral regions. The Nimbus satellites were launched aboard Thor-Agena rockets and Delta rockets.
Artist's drawing of the general design of the Nimbus series of satellites. The solar-panel "wings" move throughout the day to track the Sun during the daylight part of the satellite's orbit. The 10-foot-tall satellite has the attitude control system on top, separated from a 5-foot-diameter "sensory ring" (center) with scaffolding. The sensory ring holds the batteries and electronics for each of the sensors that are mounted underneath the ring (bottom).
