Abstract

The invention provides a data table backup method and device, electronic equipment and a storage medium, relates to the technical field of computers, in particular to the technical field of cloud storage, and aims to at least solve the technical problems of low backup recovery efficiency and poor data backup effect of a database in related technologies. According to the specific implementation scheme, the method includes: obtaining to-be-backed-up data information; sending a first backup message to the first storage device based on the to-be-backed-up data information, and sending a second backup message to the second storage device, wherein the first storage device is provided with a plurality of back-end processes, the first backup message is used for requesting the first storage device to upload a to-be-backed-up data table copy to the second storage device through the plurality of back-end processes, the second storage device is used for performing data recovery on the first storage device when the first storage device is abnormal, and the information carried in the second backup message comprises metadata corresponding to the to-be-backed-up data table copy.

Description

technical field [0001] The present disclosure relates to the field of computer technology, further to the field of cloud storage technology, and in particular to a method, device, electronic device and storage medium for backing up a data table. Background technique [0002] With the development of big data, more and more enterprises use distributed databases for data backup to ensure data security. In the event of a major accident that cannot be recovered online, such as a full cluster downtime or a regional disaster, how to quickly and accurately recover the cluster offline is crucial to continue providing services to users. [0003] In the existing solution, the database is backed up by dumping Structured Query Language (SQL) statements, and then the database is restored by filling offline SQL statements. However, this solution needs to consume more time when performing data backup and restoration, and the data backed up and restored cannot be completely consistent befor...
