There is a lot of valuable information in the massive amounts of data. Any loss of data may result in a great loss. Data security cannot be ignored. There are varieties of data disaster recovery technologies. However, most of these techniques depend on the hardware devices or data redundancy greatly. This paper presents a distributed data disaster recovery technology that minimum dependence on data redundancy and hardware system redundancy. In addition, this technology has nothing to do with the user equipment and application data structures. The test proved that this new data disaster recovery method can not only enhance disaster recovery capabilities and reduce the redundancy of the system greatly, but also suitable for large-scale distributed data disaster recovery.
