烟草异地数据灾备系统的研究与实现

随着烟草各信息系统的地域集中和数据中心的建立，数据逐步集中到各市烟草公司，原有以EMC阵列和Veritas Storage Foundation存储管理系统为核心的主机存储备份系统，由于不具有异地容灾的功能,不能满足当前的信息化安全要求。在调研浙江省烟草各市公司的基础上，提出了异地迁移和新增主机二种异地数据容灾备份方案。异地迁移就是把现在的小型机和存储设备进行合理的分离，布置到二个不同的机房；新增主机就是尽量不改变老机房的基础上，在新机房增加小型机和存储设备的方法。经过实际运行，异地迁移和新增主机方案，既保护了原有投资，又很好地解决了数据异地容灾备份问题。

Research and Implementation of Tobacco Different Data Disaster Backup System

Along with tobacco information system region centralism and data centre establishment, data concentrate gradually. Being lacking in different data disaster backup functions, the system based on the EMC array and the Veritas Storage Foundation cannot satisfy the present informationization safety requirements. On the basis of investigations and studies in Zhejiang Province, this paper designs 2 disaster backup plans: different migration and additional computer. Different migration plan is to separate the storage device from the present computer and put them in two different engine rooms. Additional computer plan does not change the original computer room, but adds new computer and storage device in the new computer room. In practice, these two schemes can protect the original investment and solve the problem of disaster backup.
