With the deepening of university informatization development, more and more university digital resources generate. The application of big data and cloud computing is becoming more and more popular today. The transition of university digital resources to cloud data center has become an effective way to solve the storage and usage of digital resources in colleges and universities.“ Double live”data center can back up the data of traditional data center into the cloud data center, to enhance the reliability and continuity of data application, reduce the pressure of local equipment, and improve the equipment efficiency. This paper firstly gives an overview of the“double live”data center, introduces its construction contents and backup mode; secondly, it designs the“double live”data center, analyzes of user needs and proposes the design scheme; finally, the implement verifies the feasibility and practicability of the plan.
