Abstract

The invention relates to the technical field of cloud computing, and discloses a cloud disk data backup method and device, electronic equipment and a readable storage medium. The method comprises the steps of obtaining a to-be-backed-up cloud disk and to-be-backed-up data corresponding to the to-be-backed-up cloud disk; detecting whether the to-be-backed-up data is valid; and when the to-be-backed-up data is valid, writing the to-be-backed-up data into the object storage corresponding to the to-be-backed-up cloud disk for data backup. By implementing the method and the device, the backup of invalid data is avoided, the space occupation of the invalid data in object storage is reduced, the backup data volume is reduced, and the backup time is saved, so that the backup efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of cloud computing, in particular to a cloud disk data backup method, device, electronic equipment and readable storage medium. Background technique [0002] When the current cloud disk is backed up from the distributed block storage system to the object storage, incremental backup or full backup can be performed, but the first backup must be a full backup, that is, the backup policy will be bound when executing the backup policy All cloud disks of the cloud are backed up from the distributed block storage system to the object storage system, and the user front-end interface is notified of the backup result asynchronously after the backup is completed. However, the backup time required for full backup is particularly long, especially for terabyte cloud disks, the required backup time will be longer, resulting in lower backup efficiency. Contents of the invention [0003] In view of this, the embodiments o...
