Nowadays digital data is produced at an exponential rate. The predominant storage and long term conservation solutions use power-hungry spinning disks. DNA technology represents an ideal candidate for storing data because of the optimum ratio between energy and density of information it can contain, its relative longevity and above all its status at the foundation of life, preserving it from any technological obsolescence. Consequently, in this paper we present the design of a scalable archiving solution based on DNA, interfaced to OAIS-compliant digital repositories, and which allows an effective and efficient implementation on the long term in a perspective of saving research and patrimonial information.
