ESSArch Digital Archive vs NetApp SnapLock

ESSArch Digital Archive is an open-source solution for long-term preservation of digital information. It is storage independent and can be integrated into an existing environment. Its OAIS-compliant archival model covers pre-ingest, ingest, preservation, access, data management, administration, and management; individual components can also be used separately. Documented workflows include preparing and submitting information packages, receiving and approving ingests, accessing storage units, and disseminating material. Archive maintenance functions include appraisal, format conversion, archival description management, and migration between storage targets. A REST API documents endpoints for descriptions, events, packages, search, storage, profiles, notifications, and orders. Deployment documentation covers Docker and Python installation, plus an automatic installer for several listed Linux distributions. Supported server systems also include Windows Server 2019. The software is free and open source; service and support are regulated through a maintenance contract. ESSArch was founded in 2002 and is headquartered in Saltsjö-Boo, Sweden. Its stated customers include public- and private-sector organizations, including the National Archives of Sweden and Norway.
