Seismic data security has become a key factor for determining the location and scale of oil and gas reservoirs in the field of oil and gas exploration.Data backup is an important part of data security,this paper analyses the seismic exploration business requirement,combines with the actual situation of the existing seismic data processing and interpretation application system,a solution based on hierarchical data backup system is put forward.The solution can effectively solve all kinds of centralized backup and restoration of seismic data,expansion of storage subsystem of seismic data processing and interpretation application system and data migration for different hierarchical storage,ensuring the data security of oil and gas exploration.
