数据复制技术在人口信息管理系统中的应用

The Application of Data Replication Technology in Population Information Management System

数据复制是一种实现数据分布的方法,是指把一个系统中的数据通过网络分布到另外一个或者多个地理位置不同的系统中的方法。DRBN作为一个共享的网络存储器,通过网络来镜像数据,实现了数据复制。

Data Replication is commonly used in data distribution, which means copy the data information from source system to target system in different positions. DRBD is a block device which is designed to build high availability clusters. This is done by mirroring a whole block device via （a dedicated） network.
