Abstract

An embodiment of the present invention provides a data backup method, a backup device, an electronic device, and a storage medium, wherein the method includes: receiving the service data to be backed up sent by the master copy storage node; information exchange, and jointly store the full amount of data of the primary copy storage node with the delayed copy storage node. The data backup method, backup device, electronic equipment, and storage medium provided by the embodiments of the present invention can back up the business data to be backed up with a data volume equivalent to three times the business data to be backed up on the premise of ensuring the reliability of the business data to be backed up , so that when backing up the business data to be backed up in the production center, the amount of data occupied can be reduced.

Description

technical field [0001] The invention relates to the technical field of data backup, in particular to a data backup method, a backup device, electronic equipment and a storage medium. Background technique [0002] A data disaster recovery system usually includes a business center and a data backup system. The business center usually deploys servers and storage systems in the computer room for normal business operations. The business center generates business data to be backed up; the data backup system deploys database servers and storage arrays in different places to store the business data to be backed up in multiple These copies can be located in the same computer room or in different computer rooms (deploying the copies in different computer rooms can avoid the loss of all copies due to the failure of a single computer room). When the data backup system backs up data, it can be a synchronous backup of the business data to be backed up, or an asynchronous backup of the bu...
