In the era of cyber economy, all kinds of digital information have exploded and played an increasingly important role in all walks of life. As information storage technology can achieve the data storage security, efficiency, reliability, manageability and rapid recovery and other characteristics, therefore, as the status of digital information in the enterprise resources continue to rise, especially in the United States last year, “9.11 ”The incident has caused some enterprises suffered serious losses due to data loss, storage technology has caused unprecedented attention. Currently, the research and application of storage technologies mainly focus on the following areas: storage backup, replication and synchronization, network storage, virtual storage and so on.
