Abstract
A data storage system uses the free space that is not yet filled with data after the deployment of the data store. The free space is used to store additional ‘opportunistic’ protection information for stored data, possibly above and beyond the specified protection level. As the system fills up, the additional protection information is deleted to make room for more data and specified protection information.
