Abstract
An object is divided into SDfirst-level pieces. Each first-level piece is stored in a first-level container on a first-level storage entity. A redundant encoding of the first-level containers is stored in RLadditional first-level containers on RLadditional first-level storage entities. On each of the first-level storage entities, the locally-stored first-level container is divided into SDlocal second-level pieces. Each second-level piece is stored in a second-level container on a second-level storage entity of the specific first-level storage entity. Each first-level storage entities contains SDplus RLsecond-level storage entities. A redundant encoding of the second-level containers is stored in RLadditional second-level containers on RLadditional second-level storage entities. The stored object is retrievable where any specific RLones of the first level storage entities are not available, and any specific RLones of the second-level storage entities of each remaining first-level storage entity are not available.
