摘　　要：传统的灾备架构普遍存在业务恢复时间长的问题,不能适应金融行业的发展。双活技术为提高RTO指标指出了一个方向。通过对目前金融行业灾备架构中几种常用数据复制实现方式的比较,得到不同方式与RTO指标的关系,说明使用应用级复制方式实现双活是达到RTO最高指标的可选技术方案,着力分析了自动切换原理,指出这两点是双活技术的实现条件。经实践证明,提出的双活灾备架构是行之有效的。Traditional disaster recovery framework cannot adapt to the development of financial industry because of the ubiquitous problem of long business recovery time. Dual-active gives a direction to improve RTO indicators. By comparison of several frequently used implementa- tion ways of data replication in current disaster recovery framework for financial industry, we get the relationship between different ways and the RTO indicators, they indicate that by using application-level replication to realise dual-active is an optional technological ＇scheme to reach the highest indicators of RTO. We focus on the rationale of automatic switching, and point out that these two are the conditions to realise the technology of dual-active. Proven by practice, the dual-active disaster recovery framework nronosed in the article is effective.
