The invention discloses a data reproduction method of cooperative office system application level disaster recovery system. The method comprises the following steps: a cooperative office system correspondingly sets a reproduction mechanism according to data types, and according to difference of usage requirements of a local file of a disaster recovery center, respectively uses middle file asynchronous reproduction and application file redundant uploading methods to perform reproduction; more local files of task cooperation exist, since timeliness requirement of region isolation on data reproduction is not high, a between-center file asynchronous reproduction method is used; official document transmission and data exchange belong to a data exchange center, the application file redundant uploading method is used, and pressure of real-time reproduction is shared in a service operation process of each time. The key of realizing active-active disaster recovery in the method provided by theinvention is unification of back-end data of two centers.
