A multiple computer system incorporating redundancy is disclosed. Data to be stored (A, B, C) is distributed (A 1 , A 2 , A 3 , . . . B 1 , B 2 , B 3 , . . . C 1 , C 2 , C 3 , . . . ) amongst a multiplicity of computers (M 1 , M 2 , . . . Mn). A parity form (P[A], P[B], . . . ) of the stored data is created by use of a reversible encoding process. The parity form data is preferably cycled amongst the various computers. In the event of failure of one of the computers the lost data can be re-generated.
