摘要
Disclosed are a database information backup method and recovery method, an electronic device, and a computer readable storage medium. The backup method comprises the following steps: S1: a server receives a backup task instruction, and mounts a storage volume to a client; S2: the client receives the mounted storage volume, determines whether the backup task instruction is for full backup, if yes, executes S3, and if not, executes S4; S3: the client starts a CDP thread; S4: the client starts a VSS to create a volume shadow copy for a production volume of a database to be backed up; S5: the client determines whether the backup task instruction is for full backup, if yes, executes S6, and if not, executes S7; S6: the client backs up valid data in the volume shadow copy to the storage volume; S7: the client backs up, according to the CDP thread, corresponding data to the storage volume from the volume shadow copy; S8: the server creates a storage volume snapshot and a time point; and S9: the server uninstalls the mapping for mounting the storage volume.
