[0002] As cloud computing based on openstack technology is widely used, users have higher and higher requirements for data security and recoverability of openstack cloud hosts. An existing snapshot method is to take a snapshot of the disk of the cloud host Snapshots, however, when the disk data of the snapshot is used for data restoration, the state of the cloud host at the moment of the snapshot may not be restored, and the effect of the snapshot is poor

The invention discloses a cloud host snapshot method, system and device and a computer readable storage medium, and the method comprises the steps: carrying out the snapshot of a memory of a target cloud host, and obtaining memory snapshot information; storing the memory snapshot information; forbidding the target cloud host to execute the task; snapshotting a disk of the target cloud host to obtain disk snapshot information; establishing an association relation between the memory snapshot information and the disk snapshot information; and storing the disk snapshot information and the association relation. According to the cloud host snapshot method provided by the invention, snapshots are respectively carried out on the memory and the disk of the cloud host to obtain the memory snapshot information and the disk snapshot information, so the memory and the disk of the cloud host can be subsequently recovered to the snapshot moment according to the memory snapshot information and the disk snapshot information, the recovery effect of the cloud host is improved, and the snapshot effect is good. According to the cloud host snapshot system and device and the computer readable storage medium provided by the invention, the corresponding technical problems are also solved.
Description
technical field [0001] The present application relates to the technical field of snapshots, and more specifically, to a cloud host snapshot method, system, device, and computer-readable storage medium. Background technique [0002] As cloud computing based on openstack technology is widely used, users have higher and higher requirements for data security and recoverability of openstack cloud hosts. An existing snapshot method is to take a snapshot of the disk of the cloud host However, when the disk data of the snapshot is used for data restoration, the state of the cloud host at the moment of the snapshot may not be restored, and the snapshot effect is poor. [0003] To sum up, how to improve the snapshot effect of the cloud host is an urgent problem to be solved by those skilled in the art. Contents of the invention [0004] The purpose of this application is to provide a cloud host snapshot method, which can solve the technical problem of how to improve the snapshot ef...
