The important means for ensuring the continuity of the service is to improve the high reliability of the information system, and a remote disaster recovery system which can resist or resolve various situations needs to be built. The core of the disaster recovery system is to solve the disaster, so that the safety of service data is ensured, and the continuity of the service is ensured. Data security needs to ensure integrity, reliability and consistency of user data. The data security is the foundation of the disaster recovery system and also the guarantee that the disaster recovery system can work normally; the service continuity is a construction target of the disaster recovery system, and it must be realized by good coordination among various resources such as an application system, a network system and the like on the basis of reliable data backup. In order to establish a high-reliability system, such as a machine room damage and other serious natural disasters, a remote disaster backup center needs to be established, and a user sends locally backed-up data to a place far away from the local place to store and resist the disaster. After a disaster occurs, purchasing and installing a backup hardware platform according to a preset data recovery program, and recovering a system and data. The method for realizing the remote copy of the data has two ways, namely a software way and a hardware way. The software mode is realized by host-side software, such as remote volume copy or remote data backup tool provided by a database manufacturer, to realize remote copy of service data. A remote data system is established, and the system is a copy of the key application data of the production center. Replication may be through hardware-a synchronization technique of disk arrays; the tool may also be remotely replicated through software-remote volume mirroring and databases. When a disaster occurs in the production center, the production data is still available in the backup center, and can be realized in a hardware (disk array) or software mode. The method is characterized in that a scheme integrating local data, remote data and application disaster tolerance is established, the consistency of the data is guaranteed to the maximum extent, the disaster tolerance level is sequentially improved, the disaster tolerance level is based on the local data, the remote data and application disaster tolerance level can be implemented step by step, the early-stage investment is protected in the later stage, a manual/automatic disaster tolerance scheme can be supported, and a user can freely select the disaster tolerance level according to needs, so that the disaster tolerance level is the target and the starting point of.
