基于云计算的PC数据同步备份的研究与实现

Research and implementation of PC data synchronous backup based on cloud computing

为了更好地保证数据安全性、完整性及方便数据的异地管理,从本地数据库和个人数据角度出发,以数据备份为重点,利用微软云端数据库管理系统SQL Azure和应用程序开发工具Visual Studio,设计并实现了基于微软Windows Azure云环境下的PC数据同步备份系统,并借此平台发布和部署了该系统的Web门户网站.实验测试表明:相比于其他非云环境下的数据备份方法,该系统在移动性、操作性和数据管理等方面具有一定的优势和研究价值.

In order to better ensure data security,data integrity,and facilitate remote management,this paper has designed and implemented a system model for PC data synchronous backup from the view of the local database and personal data.It focuses on the data backup and uses SQL Azure（a cloud database management system）and Visual Studio（a development platform tool）.Also the system is released and deployed on the Windows Azure Platform with a unique web portal.Experimental tests show that compared to other data backup methods in non cloud environment,the system has certain advantages and research value on mobility,interoperability and data management.
