Abstract: A data storage caching architecture supports using native local memory such as host-based RAM, and if available, Solid State Disk (SSD) memory for storing pre-cache delta-compression based delta, reference, and independent data by exploiting content locality, temporal locality, and spatial locality of data accesses to primary (e.g. disk-based) storage. The architecture makes excellent use of the physical properties of the different types of memory available (fast r/w RAM, low cost fast read SSD, etc) by applying algorithms to determine what types of data to store in each type of memory. Algorithms include similarity detection, delta compression, least popularly used cache management, conservative insertion and promotion cache replacement, and the like.

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.
