Based on the current status of data center of ministry of land and resources （MLR） , this paper discussed two technique schemes of data disaster backup center construction, i.e., synchronous transfer technique and asynchronous transfer technique. Also, the two schemes＇ implementation was discussed through storage layer, server layer and database system layer. Furthermore, this paper analyzed the framework, hardware equipment and technique peculiarities of the two schemes. Moreover, this paper compared the following aspects of the two schemes： data security, influence on application system, transfer distance and bandwidth, application situation. The above work could provide some tips for data disaster backup center construction in the same city.
