The Archiver project, initiated in January 2019, aims to enhance digital preservation and archiving for petabyte-scale data under the European Open Science Cloud (EOSC) framework. The pilot phase, announced in a ceremony on November 29, 2021, follows a successful prototype phase where consortia developed innovative solutions for long-term data preservation. The project involves extensive collaboration with research organizations and focuses on ensuring data integrity, security, and usability for scientific data across various domains.
