Storage is arguably the most fundamental building block of any technical infrastructure designed to preserve digital content. All institutions responsible for preserving digital content must use storage systems or services, whether they are maintaining their own, sharing infrastructure with other institutions, or relying on a third party to provide this service. There are many decisions to be made as to what constitutes a storage infrastructure good enough to protect the integrity and viability of the content, at a cost affordable to the institution. To date each institution has had to independently make these decisions without guidance from the digital preservation community. This workshop will explore whether or not it is possible for the attendees to write a brief “principles of preservation storage” as a starting point for a larger discussion within the community after the conference.
