The cloud technology double live data center information system research and design based on disaster recovery platform

摘要

In the current information age, usually the data resources are much higher than the value of the computer equipment itself. In recent years, with the rapid development of network technology, the formation of a high concentration of data stored in the network environment, the simplified data management, improve operational efficiency, reduce the cost of investment at the same time, the data security is experiencing more severe test. As a kind of data disaster recovery data security technology, through a complete copy of the data in real time to the disaster recovery center, in order to keep a copy of the basic means of providing a last line of defense for the security of the data. Since the disaster recovery started, people have made a lot of research, but there are still some problems first, as the diversification of the storage subsystem structure of infrastructure, so to build a disaster recovery system need to do a lot of personalized treatment followed by a single, storage technology has been unable to meet the needs of various industries on the disaster intensity of third and if the security of the backup data cannot be guaranteed, for sensitive confidential data, even worse than no backup. To solve the above problems, this paper related to the key technology of disaster recovery data backup based on virtual storage research, the main work is as follows. Based on the characteristics of storage technology in disaster tolerant system in the analysis, choose to use the virtual storage technology support as the basis of disaster recovery system to realize data backup, and through in-depth analysis of the virtual storage technology and its application status in the disaster recovery system, pointed out that the current application of virtual storage technology in disaster tolerant system in the challenge and the starting point of this article. Analysis of the structure of the internal computer system with virtual memory and the disaster recovery system based on the needs of the design of a virtual network storage model and disaster tolerant architecture based on this model. The advantages and disadvantages of three virtual memory mapping mechanism at present, designed for disaster recovery system virtual memory mapping mechanism and cache mechanism. On the basis of this mapping mechanism is established on data disaster tolerance strategy can be realized, and the upper user language abstraction, form a complete set of disaster recovery mechanism. Through a detailed analysis of the virtual disk transparent encryption mechanism, proposed the use of the mechanism to realize the transparent protection of backup data, combined: with the characteristics of backup data, and optimized the virtual disk transparent encryption mechanism, focus on strengthening the management of keys, the encryption mechanism is analyzed on how the role of disaster recovery system.
