Problems solved by technology
[0003] Related technologies usually use LAN backup and LAN-Free backup to back up virtual machine data. Among them, LAN backup is to deploy a backup agent and a set of backup servers in the production system, and the data generated in the production system is transmitted to the backup server through the backup agent. This solution occupies a large amount of computing resources, storage and network resources of the production system, and is not suitable for data backup of large amounts of data
The LAN-Free solution is directly backed up from the data disk to the backup server through the data network. It does not need to occupy the network resources of the service but needs to occupy computing resources.
Occupying production server resources for data backup not only requires high production server hardware, but may even affect the normal operation of the production server

The invention discloses a data backup method and device based on a cluster file system and a computer readable storage medium. The method comprises the following steps: deploying the same storage areanetwork for a production server and a backup server in advance; enabling the production server to format into a cluster file system according to the LUN provided by the storage system or the disk array so as to provide virtual storage resources for the cloud platform virtual machine; reading metadata information of the virtual machine to be backed up from the cluster file system based on the filename of the virtual disk corresponding to the virtual machine to be backed up and the data storage format of the virtual disk; determining the storage position of the data to be backed up on the LUNaccording to the metadata information, the data backup type, the SCSI identification number of the LUN where the virtual machine to be backed up is located and the file name of the virtual disk; and backing-up the to-be-backed-up data read from the storage position. Virtual machine data is backed up on the basis of not occupying production server resources.
Description
technical field [0001] The present application relates to the technical field of backup of virtual machine data resources, in particular to a data backup method, device and computer-readable storage medium based on a cluster file system. Background technique [0002] Data backup is the basis of disaster recovery. By copying all or part of the data set from the hard disk or array of the application host to other storage media, it can effectively prevent data loss caused by system operation errors or system failures, and ensure data security. With the rapid development of cloud technology, virtual machine data on the cloud platform also needs to be backed up. [0003] Related technologies usually use LAN backup and LAN-Free backup to back up virtual machine data. Among them, LAN backup is to deploy a backup agent and a set of backup servers in the production system, and the data generated in the production system is transmitted to the backup server through the backup agent.
