DuraCloud Vault is a hosted service offered through a partnership between DuraSpace and Chronopolis that provides an end-to-end solution for long-term access and preservation services of academic and scholarly data for members of the Digital Preservation Network (DPN).


Users upload their content to the DuraCloud Vault web-based dashboard and can then create a “snapshot” of the content that will be automatically transferred to Chronopolis. Content health checks are conducted as the content is transferred and a content manifest is generated. After the transfer is complete, Chronopolis (a preservation node in the DPN network) creates replicas of the content and transfers it to a minimum of two other nodes in the DPN network, where it is then monitored for a minimum of 20 years. As an added benefit, additional details about content stored in DPN are available in the DuraCloud Vault interface.

DuraCloud Vault also plans to make additional services available to DPN members who elect to store content through the DuraCloud Vault node. Both DuraSpace and Chronopolis are excited to work with DPN members to refine and test value-added services that would be a benefit to the entire DPN membership.


Currently only DPN members are eligible to use DuraCloud Vault. Alternatively, later this year organizations who are not DPN members but still wish to store content with Chronopolis will be able to sign up for a regular DuraCloud subscription and select Chronopolis as one of the storage providers enabled in their DuraCloud account.


DPN services are scheduled to launch in the beginning of 2016. Please contact us and indicate your interest in DuraCloud Vault services.

Digital Preservation Network (DPN)

The Digital Preservation Network (DPN) is the only large-scale digital preservation service that is built to last beyond the life spans of individuals, technological systems, and organizations. The DPN service provides members of the academy and their successors with a guarantee that future access to their scholarly resources will be available in the event of any type of change in administrative or physical institutional environments. By establishing a redundant and varied technical and legal infrastructure at multiple administrative levels the survival, ownership, and management of preserved digital content in the future is assured for Digital Preservation Network members.
