Provided in an embodiment are a copy storage device and copy storage method, comprising: partitioning mutually dependent Master space and Slave space for a Master and a Slave, and respectively performing data reading and writing operations and the like in the Master space and the Slave space; differentially processing a Master write request and a Slave write request, thus shortening processing time delay of the write request and improving write capability of a distributed system; using different files on a non-volatile storage medium to respectively store the records carried in the Master write request and the Slave write request so as to separately store the Master and the Slave, thus decreasing the number and size of files to be found when searching the Master records, and improving read capability of the distributed system, while reducing data traffic to be filtered when the range of the Master and the Slave changes, and reducing resource consumption of the distributed system. |
