Research and Implementation of Tobacco Different Data Disaster Backup System
烟草异地数据灾备系统的研究与实现

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.
