Abstract

The embodiment of the invention discloses a data backup method, device and system for a database cluster, and is used for solving the problems of tedious backup process, low backup efficiency and success rate, influence on production and operation of the database cluster and the like in the existing backup scheme. The method comprises the steps that on the basis of running state information and load capacity information of serviceable nodes in a target database cluster, backup nodes used for executing a target backup task are determined from the serviceable nodes of the target database cluster, and the target backup task is used for backing up target data of the target database cluster; determining a task execution plan of the target backup task based on task related information of the currently executed backup task; and scheduling the backup node to execute the target backup task based on the task execution plan.

Description

technical field [0001] The present application relates to the technical field of databases, and in particular, to a data backup method, device and system for a database cluster. Background technique [0002] At present, for data backup of a database cluster, the backup nodes in the database cluster are usually designated manually, and a timing mechanism such as crontab is used to execute the backup task for the database cluster at a specified time point. However, once the backup node is abnormal or the backup time is improperly selected, it will not only lead to backup failure and affect the generation and operation of the database cluster, but also require manual intervention and adjustment of the backup node and backup time for all subsequent backup tasks, which will lead to cumbersome backup process. , The backup efficiency is low. SUMMARY OF THE INVENTION [0003] The purpose of the embodiments of the present application is to provide a data backup method, device and ...
