A remote replication synchronizing/accessing system and a method thereof applied between a local system and a remote mirroring system of the local system. After the remote mirroring system is created, an initialization synchronous operation of the remote mirroring system is sequentially performed according to a sequence of data blocks in storage of the local system. A small-granulated exclusive lock function is established between the initialization synchronous operation and a data-accessing request operation of the local system. During the initialization synchronous process of the remote mirroring system, it is determined whether a data block position corresponding to the current initialization synchronous operation is the same as that corresponding to the data-accessing request operation or not. Finally, according to a position determination result and the small-granulated exclusive lock function, a data-accessing request is directed processed or processed after finishing the initialization synchronous operation.
