源结构无关的远程备份数据共享存储方法

针对远程容灾系统中备份数据的存储依赖数据源的结构特征和备份中心资源浪费严重的现状，提出一种远程备份数据存储方法。通过数据封装、存储空间动态分配等技术实现多备份任务的备份数据在共享的存储空间内存储，备份中心与备份数据源的存储结构无关。实验证明，该方法不仅提高系统资源的使用效率，而且能提供较好的存储性能。

Space-shared Storage Method of Source-structure-independent Remote Backup Data

Due to the backup data storage structure of remote disaster tolerant system depends on the data source, the resource in the backup center is extremely wasted. According to this problem, this paper presents a remote backup data storage method. With the backup data been encapsulated and storage space allocated dynamically, the method supports multi-tasks’ backup data be stored in the shared storage space and the storage structure of the backup data in the backup center be independent of the data source. The experiment proves that the method not only can improve the efficiency of system resource, but also can provide better storage performance.
