Abstract

The invention belongs to the technical field of data processing, and discloses a data backup method, device, equipment and storage medium. The present invention determines the backup record area in the cluster disk when obtaining the read and write authority of the cluster disk in the failover cluster, obtains the corresponding historical backup information in the backup record area, and determines the data to be backed up in the cluster disk according to the historical backup information , and incrementally back up the data to be backed up. Compared with the prior art, which can only perform full backup when obtaining the authority of the cluster disk in the failover cluster, the present invention determines the data in the cluster disk according to the historical backup information in the backup record area when obtaining the read authority of the cluster disk. The data to be backed up, and the data to be backed up are incrementally backed up, realizing the incremental backup of the cluster disk, effectively avoiding the need to perform full backup again after the cluster disk permission is transferred, and improving the efficiency of cluster disk data backup, effectively Backup time is saved.

Description

technical field [0001] The present invention relates to the technical field of data processing, and in particular, to a data backup method, device, equipment and storage medium. Background technique [0002] With the development of science and technology and the progress of society, data security is becoming more and more important, so data is generally stored in cluster disks. In the existing cluster disk data management, only one master server has read and write permissions to the cluster disk at the same time. Therefore, when the master server fails, the read and write permissions of the master server will be transferred to the failover where the master server is located. on other standby servers in the cluster. [0003] In the prior art, when the standby server takes over the read and write permissions to the cluster disk, the standby server does not know the data written by the failed server. Therefore, the standby service can only perform full backup when backing up t...
