1. A method for data storage in a distributed data storage system with redundancy, the method comprising:

  • dividing a data set into a plurality of data blocks using an (N,K) algorithm;

    defining a minimal number K out of N data chunks needed to restore one data block;

    disassembling each of the data blocks into at least L different data chunks, wherein K≦

    L≦

    N; and

    distributing the at least L data chunks to storage elements of the distributed storage system.
