The University of Edinburgh identified a gap for preservation of large research data sets that do not need active preservation at ingest as the majority of the content will not be retained beyond the initial retention period. The complexity of content types, size and quantity of data also means that active preservation is not currently achievable with the resources available. The initial retention periods are set by the research funders and are generally 5-10 years. The solution provides permanent dataset identifier (DOI) and data discoverability through linkage to PURE (University’s Current Research Information System (CRIS)) as well as storage on the university’s secure storage platform. Three copies are kept with one being held in the Cloud. Whilst developing the DataVault, changes to data protection legislation across the European Union impacted system development. All datasets are now encrypted at rest.
