The Application of Remote Backup system in Public Library Business-Taking Shenzhen Library as an Example

摘要：随着深圳“图书馆之城统一技术平台”的快速整合，越来越多的应用数据合并到深图的DILAS数据库中。这些数据的安全性和业务的连续性尤为重要。业务量的增加，也导致读者服务的故障率居高不下。如何对数据进行高可靠I}生的备份和如何降低故障率，是迫切需要解决的问题。目前数据备份的最高层次是异地备份，它利用快照和恢复等技术，实现数据与应用的高可用性。文章描述了深图异地备份系统的设计与建设，通过该系统的搭建，“图书馆之城统一技术平台”的数据安全级别将得到全面的提升，应用故障率大幅度降低，实现了数据与应用安全统一的局面和价值。

With Shenzhen ＂ library city unified technical platform＂ rapid integration, more and more application data merge to Shenzhen Library＇s DILAS database, The dam＇s security and business continuity are especially important. Due to the increase in volume of business, the failure rate of reader service is very high. How to reduce the failure rate and how to realize the high reliable data backup, are the questionsin urgent need of solving.. This paper mainly describes the design and construction of Shenzhen Library＇s different ground disaster recovery system. Through the construction of the system, ＂The library city unified technical platform＂ data security rating will be fully promoted, and the failure rate of reader service will be greatly reduced. The situation unity of data storage and business application will be realized.
