介绍了电信灾备体系,基于二层网络互通,提出了跨数据中心实施业务容灾备份迁移的电信私有云灾备体系思路,并对数据中心跨节点容灾备份方案进行了详细论述。 This paper introduces the telecom disaster recovery system. Based on the layer 2 network interworking, this paper proposes a private telecommunication disaster recovery system that implements business disaster recovery and backup migration across data centers. In addition, it discusses the disaster recovery and backup scheme across nodes in a data center in detail.
