摘　　要：对信息系统数据备份恢复技术进行了研究,提出了一种适用于实时数据库系统的数据备份恢复方法,以解决在生产环境中,不影响上层业务系统的前提下,安全、稳定、高效的数据备份以及数据恢复问题。其中,增量备份及恢复过程采用了基于文件块级别的备份处理方式,相比于数据节点级别的处理方式,访问磁盘I/O频率低,处理速度快,提高了备份效率,极大减少增量备份过程对实时数据库及其应用的影响。最后以实例证明了该方法的可行性。The technology of data backup and recovery on information system was researched,and a data backup and recovery method was proposed for real-time database system,in order to solve the problem of data backup and data recovery safely,stably,and efficiently in the production environment,without affecting the top business systems.Among them,incremental backup and recovery process used a file block level backup processing method,compared to the data node level processing,the low disk I / O frequency,high processing speed and backup efficiency,greatly reduced the influence of incremental backup process on real-time database and its application.Finally,the feasibility of the method was demonstrated by an example.
