基于云计算的低冗余远程智能恢复系统的实现

摘要

Computer users increasingly widespread ,the Integrity and availability of computer software or operating system are destructed by many causes of data tampering. However, when computer users in the choice of the data recovery method,they fell into problems such as the low performance of data recovery or large amount of the unnecessary data redundancy.This paper analyze and discuss the current computer data security and data backup mechanism. the secure storage and distribution mechanism of shared data and the dynamic software snapshot generation technology based on the relation of registry are designed in our research.based on the research, the implementation of low redundancy and remote intelligent recovery system based on cloud computing are designed and implemented, which included the genration of software snapshot and system snapshot, the snapshot detection,the snapshot recovery,the protection of software startup and the low redundancy cloud storage.%　　随计算机使用者的范围日益广泛，诸多原因导致的数据受篡改，使得计算机软件或操作系统的完整性和可用性遭到破坏。然而计算机使用者在选择数据恢复方式时，却遇到数据恢复性能偏低、数据流量冗余量大等困境。文章以Windows操作系统为基础，对当前计算机的数据安全问题和数据备份机制进行了分析和论述，设计了共享数据的低冗余安全存储与分发机制和基于注册表关联的动态软件快照生成算法。并在此基础上，设计并实现了基于云计算的低冗余远程智能恢复系统，包括软件快照、系统快照、快照检测、快照恢复、软件启动保护、低冗余云存储等系统功能。
