Rucio: scientific Data Management

Rucio is an open-source scientific data management system created at CERN to handle the exa-scale data needs of modern scientific communities. Built on more than a decade of experience, its key features are to organise, access, transfer, monitor and recover large volumes of data spread across heterogeneous storage systems in globally distributed locations

Declarative data management allows you to say what you want, and let Rucio figure out the details how to do it. Manage your data with expressive statements. Three copies of my file on different continents, and have one backup on tape? Automatically remove it once its access popularity goes to zero? No problem.
