Backup method and device of cloud host, electronic equipment and storage medium

The invention discloses a cloud host backup method and device, electronic equipment and a storage medium, and the method comprises the steps: carrying out the snapshot processing of a to-be-backed-up cloud host, and generating a snapshot file; segmenting the snapshot file, and determining at least one data block; determining respective backup index positions of the at least one data block and the metadata block of the cloud host to be backed up, and generating a backup metadata table according to the determined backup index positions; and according to the backup metadata table, backing up the snapshot file. Therefore, the snapshot file of the to-be-backed-up cloud host is segmented, the respective backup index position is determined, and distributed backup is performed on the snapshot file, so that the problem of single-point failure of the backup node is effectively avoided, and the reliability of the system is improved. 本申请公开了一种云主机的备份方法、装置、电子设备和存储介质，该方法包括：对待备份云主机进行快照处理，生成快照文件；对快照文件进行分割处理，确定至少一个数据块；确定至少一个数据块
