The invention relates to a domain name resolution system disaster recovery construction method. The method includes the following steps that data of a target machine cluster providing domain name resolution service are synchronized to a disaster recovery machine cluster in real time, and the data include cache data used for providing a domain name resolution basis; a domain name resolution request is received and responded to so that the cache data can be utilized to perform domain name resolution; the domain name resolution request is answered through a domain name resolution result. The invention further provides a domain name resolution system disaster recovery construction device. Due to the application of the construction method, a disaster recovery system suitable for an existing domain name service system can be constructed, and when paralysis happens to the existing domain name service system or other dependent networks, the effect of the domain name resolution service can be temporality and effectively played.
Description
technical field [0001] The invention relates to Internet security technology, and relates to a domain name resolution system disaster recovery construction method and device. Background technique [0002] The disaster recovery system is a technology for backup and disaster recovery of business systems composed of network clusters, and is widely used in Internet service clusters. Usually, Internet services are provided by the normal operation of the business system, and the disaster recovery system performs real-time backup and fault detection on the normal operation of the business system, and after the business system fails or is attacked, the disaster recovery system can be used intelligently The system replaces the original business system and opens the same service to Internet users. [0003] A disaster recovery system usually includes several major management logics of data synchronization, fault detection and business switching. Among them, the data synchronization m...
