一种基于DG的TB级数量容灾研究与实现

Research and Implementation of a TB Number of Disaster Recovery Based on DG

数据库迁移之后的容灾研究是一个极具挑战的领域,数据库的部署应能及时发现问题并对数据采取相应的保护措施,防止数据的丢失和损坏,提高数据库的稳定性和运行效率。本文通过提出一种基于DG的TB级数量容灾方法,解决了一彩票研发中心数据库TB级数据出现的宕机问题。经过实施,彩票中心数据库实现了高效运行,具有容灾的功能,解决了两台数据库在迁移之后单纯的HA。

The disaster tolerance after database migration is a challenging field, the deployment of the database to timely found the problem and take protective measures, to prevent data damage& loss and improve the stability&efficiency of the database. With presenting a number of TB of disaster recovery method based on DG. Has solved the problem of downtime database TB in Lottery Research Center. The lottery center database has achieved efficient operation, been with the function of disaster recovery, and solved the two database after migration of pure HA.
