An IT disaster is not a small probability event. Once it occurs, the impact will become more and more severe. The regulation of various industries is becoming more and more stringent, and the requirements for business continuity are also getting more and more stringent. National BDR standards available for financial sector BDR and BDR building standards published by the People's Bank of China and China Banking and Insurance Regulatory Commission can be used to guide and standardize the BDR for business systems used in the financial sector.

There are specific regulatory requirements for financial sector BDR. They are more stringent than those in other industries and subject to the supervision of the People's Bank of China and China Banking and Insurance Regulatory Commission. Three-centers-in-two-places is typical BDR architecture for the financial sector. They include a master data center, a BDR data center in the same city and a BDR data center in another city.
