基于NAS架构的数字化档案异质异地备份系统设计

Design of Heterogeneous Backup System of Digital Archives Based on NAS Architecture

为了提高异质异地档案备份过程中数据分配能力,缩短备份系统的响应时间过长。为此,提出基于NAS架构的数字化档案异质异地备份系统设计。硬件设计方面,对网络附加存储设备、磁盘列阵进行了设计。软件方面,对需要备份的数字化档案进行预处理,降低备份工作压力。通过NAS(Network Attached Storage)集群进行数据分配与数据分布式均衡负载处理,实现数据的管理分配合理化。经由备份代理程序和NBP协议,实现数字化档案异质异地备份。实验结果表明,在对200GB数据文件进行备份时,该系统的备份速度为6.0 KB/s,系统响应时间低于80 ms,提升了数据分配的能力。

In order to improve the data distribution ability during the backup process of heterogeneous and remote files, shorten the response time of the backup system, a digital archive heterogeneous backup system based on NAS architecture is proposed. In terms of hardware design, we design network attached storage devices and disk arrays. In terms of software, we preprocess the digital files that need to be backed up to reduce the pressure of backup work. NAS(network attached storage) cluster is used for data distribution and distributed balanced load to realize the rationalization of data management and distribution. Through the backup agent program and the NBP protocol, the digital archives are backed up in different places. The experimental results show that when the 200 GB data files are backed up, the backup speed of the system is 6.0 KB/s, and the response time of the system is less than 80 ms, which improves the ability of data allocation.
