【摘要】 本文基于虚拟磁带库(VTL)技术,搭建了一个用于提高海量数据备份性能的三级存储备份架构。通过调整备份定义中虚拟磁带库的备份驱动器和虚拟磁带库管理软件所在专用服务器端口的数量,测出增加备份驱动器或专用服务器端口数时的备份速率。根据速率变化情况,讨论了影响架构性能瓶颈的设备,得出了分析整个架构备份性能瓶颈的分析模型,根据模型和设备性能制定备份策略。更多还原

【Abstract】 Based on Virtual Tape Library technology,this paper establishs teritary storage backup architecture which is used to improve backup performance of mass data.In backup definition,by adjusting the number of Driver of Virtual Tape Library and Node of specialized server on which management software of Virtual Tape Library installs,this paper tests backup speed of Driver and Node after increasing the number of Driver or Node. According to change of speed,this paper discusses the equipment which affects architecture performance bottleneck,gets the idea of analysis model of analying the whole architecture backup performance bottleneck and decides backup strategy according to model and equipment performance.更多还原
