The invention discloses a multi-copy storage management method and system of data. The multi-copy storage management method comprises the following steps: a plurality of servers store all data needed to be stored in respective memories, and realize the synchronization of data storage among the plurality of servers; and one of other servers replaces a master server to provide data processing service by using the stored data under the condition that the predetermined master server in the plurality of servers cannot continue to provide the data processing service, wherein other servers except for the master server are prohibited from providing the data processing service. According to the storage management method and system disclosed by the invention, the data needed to be stored is saved on each data server, and data synchronization and master/slave switch are realized among the servers, so that multi-copy storage of the data can be effectively realized, backup and replacement among the plurality of servers ca
