Abstract

The invention relates to a snapshot creation method and device, computer equipment and a storage medium. The method comprises the following steps: acquiring a snapshot creation instruction; acquiring information of a disk according to the snapshot creation instruction; when it is judged that the disk does not comprise a snapshot according to the information of the disk, creating a reference snapshot; updating information of the disk based on the reference snapshot; and when it is judged that the disk comprises a snapshot according to the updated information of the disk, creating a target snapshot. By adopting the method, the snapshot creation accuracy can be improved.

Description

Technical field [0001] The present application relates to computer technology, and in particular, there is a snapshot creation method, device, computer equipment, and storage medium, and a snapshot reduction method, device, computer device, and storage medium. Background technique [0002] With the development of computer technology, snapshot techniques have emerged. The snapshot technology can be used for a snapshot that the user returns to a certain point in time, making it easy to modify or other operations for the previous file. However, traditional snapshot technologies, there is a problem that the snapshot creation is inaccurate. Inventive content [0003] Based on this, it is necessary for the above technical problems to provide a snapshot creation method, device, computer device, and storage medium capable of providing accuracy, and a snapshot reduction method, apparatus, computer device, and storage medium capable of providing accuracy. [0004] A snapshot creation meth...
