Backup method and device of cloud host and electronic equipment

The invention provides a cloud host backup method and device, and electronic equipment and relates to the technical field of computers, the method is suitable for a host machine, and the host machinecorresponds to at least one storage device and is used for storing data of a cloud host; the method comprises the steps that when a backup request is received, sending a sealing instruction to a cloudhost, so that the cloud host operates a daemon process to seal a file system of the cloud host according to the sealing instruction; creating backup snapshots of all storage devices; sending an unsealing instruction to the cloud host to enable the cloud host to run a daemon process to unseal the file system; and storing the backup snapshots to the storage devices. The data consistency and the service continuity can be well considered, and the service performance and the user experience of the cloud host are effectively improved. 本公开提供了一种云主机的备份方法、装置及电子设备，涉及计算机技术领域，该方法适用于一种宿主机，宿主机对应有至少一个存储设备，用于存储云主机的数据；包括：当接收到备份请求时，向云主机
