ABSTRACT:
Exemplary systems and methods in accordance with embodiments of the present invention may provide a plurality of data services by employing splittable, mergable and transferable redundant chains of data containers. The chains and containers may be automatically split and/or merged in response to changes in storage node network configurations and may be stored in erasure coded fragments distributed across different storage nodes. Data services provided in a distributed secondary storage system utilizing redundant chains of containers may include global deduplication, dynamic scalability, support for multiple redundancy classes, data location, fast reading and writing of data and rebuilding of data due to node or disk failures.
