Abstract

The invention relates to a distributed task management system with high consistency and availability. The system comprises a Web back end module and a backup server cluster which are connected through a network, wherein the backup server cluster comprises a plurality of backup servers; each backup server comprises a consistency module, a log module and a storage module which are sequentially connected; each consistency module becomes a Leader role or a Follower role through election, receives log information sent by the Web back end module and broadcasts the log information if becoming the Leader role and receives log information broadcast by the Leader role and responds to the log information if becoming the Follower role; each log module is used for storing received log information and submits the received log information to the storage module. Compared with the prior art, the system has the advantages of high consistency, high availability, lower cost and the like.

Description

technical field [0001] The invention relates to the field of distributed database systems, in particular to a strongly consistent and highly available distributed task management system. Background technique [0002] In the field of information technology and data management, backup technology is an important technical means, which is used to restore the availability of production server systems and applications on them when they fail. With the explosive growth of data information, single-node backup storage and cabinet-type backup server systems cannot better solve the problem of faster backup and recovery of massive data. Therefore, a backup system with a distributed structure emerges as the times require. [0003] The distributed structure of the backup system should be able to provide 7*24 highly reliable and highly available services. However, in the case of multi-node clusters, single node failure is unavoidable. Therefore, there is currently a master-slave system ar...
