Abstract: We are in the midst of an unprecedented transformation from physical to virtual assets. Online contracts, digital photographs, digitized movies, music, technical journals, corporate records, web sites, and government documents are just a few examples of valuable digital assets that organizations would often like to preserve for long periods of time -- not just for years, but for decades or even forever. Unfortunately, long-term preservation remains a huge challenge due to the unusual nature of the threats from which it suffers compared to traditional (shorter-term) storage applications. Our goal in this paper is to describe how these environments differ and to acquaint the dependability community with some of the challenges in building archival storage systems. We give some guidelines for an alternative storage architecture, much of which is being implemented at the British Library, and we conclude with some suggestions for initial research topics to be tackled in this area.
