Don't Believe the Hype: Archival Storage is an Economic, Not Technical Problem

This talk challenges the conventional wisdom around 'immortal' storage media solving the archival data problem. The author uses their personal backup strategy as an example, highlighting that backup and archiving are distinct problems; backups focus on recovery time, not media lifespan. Inexpensive DVD-Rs suffice for their backups. For archiving, the author argues that 'immortal' media have a small market size, long technology maturation cycles, and are inaccessible to consumers. Large cloud providers dominate archival storage, and their pricing strategies reflect economies of scale and lock-in. Finally, the author stresses the importance of retrieval strategies and cites the LOCKSS project, emphasizing the importance of redundant backups over reliance on a single expensive, durable medium.
