一种基于数据动态迁移的分级备份系统的研究

随着运营商信息化进程的不断深化，业务数据量处于高速的增长，管理信息系统的高效访问以及安全性正在变得越来越重要。本文以信息系统的数据价值评估为基础，提出一种数据动态迁移模型，并引入虚拟带库作为近线存储，形成完整的解决方案。实现传统备份到分级备份的升级改造，优化信息系统备份架构，提高数据的访问以及保护的效率。

A Hierarchical Backup System Study Based on Dynamic Migration of Data

With rapid development of informatization advancement and steep rise of total quantity of data, security and reliability of information system become more and more important. This paper introduced a dynamic migratory pattern based on dynamic value evaluation, and put forward a solution using virtual library as near-line storage. The solution optimizes the framework of backup, and the measurement indicates that the security and reliability of information system has been boosted.
