5 What does DPN do? Establishes a network of heterogeneous, interoperable, trustworthy, preservationlevel dark archives Replicates content across the network, to multiple nodes Enables restoration of preserved content to any node due to data loss, corruption, disaster, or other catastrophic event 5

17 Long Term Preservation Sustainability "Sustainable preservation strategies are not built all at once, nor are they static. Sustainable preservation is a series of timely actions taken to anticipate the dynamic nature of digital information." [1] A really important question for an archive to ask itself over and over again is, Why do we need to keep this?' - Bryan Beecher There are risks and costs to a program of action, but they are far less than the long range risks and costs of comfortable inactions. - John F Kennedy 1 - Sustainable Economics for a Digital Planet: Ensuring Long-Term Access to Digital Information. Blue Ribbon Task Force on Sustainable Preservation and Access. February
