A method of multi-buffer in remote asynchronous replication system(RARS) is preseated.The method including a model of massive cache based on Windows basic volumes [3] and a model of send cache based on memory.The definitions and implementation methods of them is given,and test and analysis of them is provided.Results show that the method resolved the problem of mismatch speed between disk I/O and network transmission,meanwhile not affect the high availability of backup services in local data center.
