摘要
NDMP协议是一种比较新的协议,基于此协议的数据管理实现了数据提供方、数据接收方以及数据管理方的三方无关性。文章在分析了NDMP的体系结构模型、工作机制的基础上,分析了NDMP的不足,并且提出了NDMP+模型,同时对基于NDMP+的备份/恢复进行了性能分析,结果表明该模型提高了网络数据管理的可扩展性同时性能有所提高。
Network based data management (NDMP )protocol is new and its purpose is to realize the irrelevance among data server,data backup and data management.On the discussing of the architecture,working mechanism of Network Data Management Protocol,this paper analyzes the shortage of the current NDMP ,and therefore puts forward the proto-type of NDMP+,meanwhile it analyzes the performance of backup/restore based on NDMP+model.The researching re-sult shows this model can improve the extendibility of NDMP and get higher performance.
