Executive Summary

One of the major issues in storage technology is finding cost-effective solutions for the long-term storage of archival data. The topic is growing in importance as more organizations now maintain larger amounts of data online. Archival storage systems differ from other storage systems in two important ways; the data they contain remain largely unmodified once they are stored. As a result, write rates are a much less important issue than in conventional storage systems and these data have to remain available over time periods that can span decades.
