Replication technology is a very important data management in cloud storage. Traditional replication control methods cannot usefully solve the load imbalance caused by hotspot access. This paper proposed dynamic algorithm based on access popularity called APDRA. Replicas were created and deleted dynamically according to of data, situation system nodes, effectively solving problem local overload hot spot recovery idle replicas. In end, superiority APDRA was verified experiment.
