Abstract

The invention discloses a data synchronization method and a data synchronization system. The data synchronization method comprises the steps that: a destination end sends a data synchronization request to a source end, wherein the data synchronization request includes a log grouping identifier of data to be synchronized; the destination end receives N pieces of log information of the log grouping identifier sent by the source end, wherein each log information at least comprises an identifier of the data to be synchronized and a first timestamp of the data to be synchronized at the source end, and the N is a positive integer; and the destination end processes the N pieces of log information of the log grouping identifier in parallel according to the method of determining a second timestamp of destination end data corresponding to the identifier according to the identifier of the data to be synchronized in the log information with regard to each log information, and acquiring source end data corresponding to the identifier from the source end so as to update the destination end data is the first timestamp is later than the second timestamp. The data synchronization method and the data synchronization system are used for solving the problem that a main-standby system data synchronization method of the existing disaster recovery system structure cannot guarantee the real-time property.

Description

technical field [0001] The present invention relates to the communication field, in particular to a data synchronization method and system. Background technique [0002] The banking industry is one of the industries with the widest application of information technology. With the rapid development of bank informatization construction, most bank information systems adopt a large centralized mode of centralized data storage and centralized processing. This centralized mode brings great benefits but also has many risks. One of the aspects is multi-point The decentralized risk of the data center is integrated into the centralized risk of the data center. Once the technical failure of the center (such as hardware failure, human error and damage caused by virus attack), the consequences will be catastrophic. Therefore, the highly reliable storage of data, the prevention of disasters, and the quick recovery methods that fully consider the consequences of disasters have become an ex...
