Automatic verification method for data consistency of virtual machine backup and recovery

Abstract

The invention relates to an automatic verification method for data consistency of virtual machine backup and recovery, the method in particular comprising following steps: S1, preparing a script or ause case to be verified; S2. writing the method needed for consistency check, writing the method related to the comparison entrance, and importing the self-defined method into the automation tool; 3,initiating backup and restoration operations on the CAS platform by mean of the API interface of the backup platform, so as to verify whether the data after backup and restoration is consistent; S4. calling the CAS platform by means of checking method and built-in library to obtain, transform, submit disk and calculate MD5 operation. Compared with the prior art, the invention is applicable to therecovery check of the disk data of the virtual machine in the H3C CAS cloud computing management platform, so that the consistency check of the data after the backup and recovery becomes simple underthe environment, the labor and time cost are saved, and the human error of the operation can be effectively avoided.

Description

technical field [0001] The invention relates to the field of computer data protection, in particular to an automatic verification method for data consistency based on virtual machine backup and recovery under the H3C CAS platform. Background technique [0002] H3C CAS virtualization software is an enterprise-level virtualization software developed by H3C for data centers, providing powerful virtualization functions and resource pool management capabilities. H3C CAS virtualization software includes CVK (Virtualization Kernel System), CVM (Virtualization Management Platform) and CIC (Cloud Service Management Center). [0003] The disk format that can support backup in CAS is QCOW2, which is a relatively mainstream virtualization image format at present, supports snapshot operation, and records some internal block allocation information inside. [0004] The RAW (naked device) format is the original image, which will be directly used as a block device for the virtual machine. I...

Problems solved by technology

[0008] The purpose of the present invention is to overcome the above-mentioned defects in the prior art and provide a method that solves the problem that the data consistency of the virtual machine cannot be effectively verified after backup and restoration, and combines it with an automated method to provide a single verification method for complex verification scenarios. The entrance, which minimizes manual participation, enables the backup and recovery data consistency to be verified effectively, conveniently and quickly. An automatic verification method based on the virtual machine backup and recovery data consistency under the H3C CAS platform
