METHOD AND APPARATUS FOR MAXIMIZING DATA RECOVERABILITY USING COUPLING UPDATES BY PARTIES
First Claim
1. A data recovery system that permits recovery of data in a computer memory, said system comprising:
- an update storage system for providing backup storage of recently updated data;
a long-term storage system for providing backup storage of data that has not been recently updated;
a coupling functional circuit for providing a bit-wise commutative binary operation of data from the update storage system and from the long term storage system; and
a parity register for maintaining parity snapshots of the output of the coupling functional circuit.

Abstract
A data recovery system is disclosed that permits recovery of data in a computer memory. The system includes an update storage system, a long-term storage system, a coupling functional circuit, and a parity register. The update storage system is for providing backup storage of recently updated data. The long-term storage system is for providing backup storage of data that has not been recently updated. The coupling functional circuit is for providing a bit-wise commutative binary operation of data from the update storage system and from the long term storage system. The parity register is for maintaining parity snapshots of the output of the coupling functional circuit.
