摘　　要：当今自然灾害频发,系统的连续性对于实时结算企业来说是一项重要问题。本文针对滁州市烟草公司,分析了信息系统及灾备系统现状,设计了一套符合滁州烟草公司实际情况的面向零数据丢失的容灾方案,该方案保证了在生产机房出现突发故障时,容灾机房可以实时接管系统业务,实现RTO、RPO趋近于0的目标。试验结果证明,该方案可以有效地保证系统的连续性和数据的一致性。As the natural disaster happened frequently nowadays, system continuity acts as an important issue for the real-time settlement company. Based on the situation of information system and disaster backup system in Chuzhou City Tobacco Monopoly Bureau, a disaster tolerant scheme of non-loss data is designed. This scheme makes the disaster tolerant room take over the business in time when outburst failure happens in the production room. In this way, RTO/RPO nearly approaches zero. Experimental results show that this scheme may make the system continuity and the data consistently.
