摘要
设计了一种新的数据备份与恢复系统体系结构,提出基于事务日志的数据备份与恢复技术、本地与异地相结合的日志同步备份方案以及操作终端集群备份方案,充分的利用事务日志,将事务日志作为系统数据备份恢复的数据来源和依据,做到数据的完全备份和完全恢复,同时提高异地同步系统的可靠性、可维修性和高效性,弥补传统的备份恢复体系中存在的漏洞,并采用多种备份手段,提升数据管理系统的安全性。
A new system architecture for data backup and recovery,is designed,a data backup/recovering technology is exploited,and the local and remote log synchronizations are integrated.The operated terminal cluster backup measurement based on transaction log is proposed.It is proved that,by fully using transaction log as the source and basis of system data backup and recovery,and raising the reliability and maintainability,loopholes of the traditional backup and recovering system could be remedied.
