In the disaster tolerant system,the method of traditional disk mirroring storage led to the storage space of remote backup center wasted and disk addressing caused the poor performance of the storage IO capability when the multitask backup data concurrency storaged.According to this problem,a remote backup data storage and management method is designed and implemented.With the space allocated dynamically based bitmap,space mapping and backup data encapsulation,the method supports multitask remote backup data storageand management.The experiment proved that the method can notonly improve the storage efficiency but also save the storage space.
