Abstract


With the continuous development of computer and communication networks , information systems service reliability issues become increasingly prominent , and recovery as an information system services - based data backup and recovery technology is facing new challenges . To support the needs of the information system service restoration study for data backup and recovery , made ??the following research : In this paper, in-depth study of existing data backup and recovery technology , and each of these technologies critical thinking characteristics, scope of application , such as a detailed study . Service organization characteristics hierarchical model to describe the relationship between the data and services , and drawing on the idea of SOA , a service-oriented data backup and recovery architecture . . Recovery process in order to improve service reliability , this paper draw on trusted computing platform in the chain of trust passed thinking a trusted authentication module introduced in data backup and recovery architecture , combined with the services of the hierarchical model of data backup restore the trust chain transfer path . In order to improve the reliability of the data source of the data recovery process , introduced in the data backup and recovery architecture the redundant design module , the introduction of redundant data recovery process . For fast and accurate recovery data , the paper in a deep understanding of the basis of the file system disk data organization , starting from the bottom of the disk data storage using the FAT32 file system \analysis to design a local the precise recovery technology , in order to achieve efficient recovery of the local data . The paper designs and implements data backup and recovery system , and its functional testing and performance analysis , comparison with traditional data recovery effect , to verify the reliability and efficiency of the key technologies in this article .
