Embodiment Construction

[0031] The content of the present invention is described in more detail below:

[0032] The technical solutions adopted are as figure 1 As shown, the function of this architecture divides the request packets initiated by the user through the proxy server, and then analyzes and merges the returned packets of all nodes, and returns them to the user.

[0033] The modules in the device are described as follows:

[0034] Agent: The agent uses the idea of ​​the MapReduce programming model and the concept of "Map (mapping)" and "Reduce (reduction)" to run its own program on the distributed system without distributed parallel programming. When the scheduling process executes the backup task, it will send an instruction to execute the backup. When these designations pass through the proxy, it will query the route, obtain the node information that needs to be backed up according to the routing rules, and then decompose the request packet into multiple request packets in the map method ...

Abstract

The invention provides a distributed database backuping method and belongs to the fields of distributed technology, routes and MapReduce models. The distributed database backuping method comprises executing a database backuping task through a scheduler according to a backuping strategy, wherein the backuping strategy can be implemented through an REST (representational state transfer) interface and a database configuration or management platform; during backuping, the scheduler transmits a backup instruction to an agent, the agent locates nodes to be backuped and operation information throughroutes and transmits backup requests to every node client through the MapReduce technology, and the clients backup databases on the nodes after receiving the backup requests. The distributed databasebackuping method can achieve safely and efficiently achieve backup of distributed MySql databases at a low cost.

Description

technical field [0001] The invention relates to the technical fields of distributed technology, routing and MapReduce model, in particular to a method for realizing distributed database backup. Background technique [0002] After the data is concentrated, the business activities of enterprises are increasingly dependent on infrastructure such as data centers and networks. How to reduce or even eliminate the impact of normal and abnormal failures on business availability has attracted the attention of the operation and maintenance team and decision-makers. . For the purpose of disaster recovery, enterprises generally build two or more data centers. The main data center undertakes the user's core business, and other data centers mainly undertake some non-critical business and back up the data, configuration, business, etc. of the main center at the same time. Under normal circumstances, the main center and the backup center perform their respective duties. When a disaster oc...
