Drawings
FIG. 1 is a flowchart illustrating steps of a method for testing automatic snapshot data recovery of a disk according to the present application.
Detailed Description
It should be noted that, without conflict, the embodiments of the present application and features of the embodiments may be combined with each other, and the present application will be further described in detail with reference to the drawings and the specific embodiments.
The application provides a test method for automatic snapshot data recovery of a disk, which is mainly characterized in that automatic snapshots of the disk to be tested are configured, before the disk generates the automatic snapshots, folders and file contents are randomly created in designated folders of the disk, and then directory information and file contents of the folders are recorded and uploaded to a server. After the cloud platform automatically generates the snapshot, the catalog and the file content in the appointed folder are randomly changed again, then the current generated automatic snapshot is called in a mode of the public API of the cloud platform to execute data recovery operation, after the disk recovery is successful, the catalog information and the file content of the appointed folder are recorded again and are sent to the server, the folder information sent twice is compared, the information is consistent, the data recovery is judged to be successful, snapshot test at the next time point can be continued, otherwise, the data recovery is judged to be failed, and error information is recorded and is used as subsequent obstacle removing.
