High-performance server-free backup model of content aware storage system

This paper proposes a server-free backup model deploy on Content Aware Storage System (CASS). The CASS is a new type information storage system which consists of three layers. In the middle is content management control layer which is the core layer of the storage system. Compare with host based, LAN based and LAN-Free backup model, this work design a series of models to fulfill server-free backup solution. Thos models includes backup task detective, detective agent, query backup activate condition, semantics derivation, storage resource balancer, de-duplication, copy agent. This server-free backup model not only speeds up the backup operation, but also off-loads the LAN and host computer, ensuring optimum performance and continuous data access on the network.
