Massive Data Continuous Data Protection Technology Research And Implementation

The rapid growth of the data and the data of high availability, safety requirements to stimulate the development of the technology of storage, storage technology has become IT infrastructure is one of the key factors for mass storage, storage network data and share data provides an effective hardware based. Facing mass data, data protection and disaster recovery is more and more important, and the original data protection methods, such as tape backup, backup window there, recovery time long, real-time response sent, affect the normal business problems, it is impossible to satisfy the current demand.Continuous Data Protection (Continuous Data Protection, CDP) is a way to not affect the main Data under the premise of operation, can achieve sustained capture or track the target any changes in the Data, and to restore to any time after the method. Continuous data protection technology can use hardware implementation can also use software to realize, this article is from the point of view of the software implementation of continuous data protection technology, and points out that the key technology of performance, and the detailed analysis. First introduced the data backup, data loss, continuous data protection system and it's in the domestic and foreign concept, research development, this paper analyzes the present situation and prospects for data protection system, and a series of problems of today have to save of data protection system of the existing defects induction; Second with the current file reading and writing data characteristics, in improving mass data IO organization and system framework is proposed on the basis of a new kind of continuous data protection systems-can be expanded the amount of data for data protection technology; Design based on the level of mass data for data protection technology system structure, the design and realization of the massive data for data protection system the client software, the design and realization of the massive data for data protection server software; Finally realizes a massive 10 data based on continuous data protection system, and analyzes the system framework each part in the function of the module.Finally analysis the realization and performance of the system, and provides a summary and outlook.
