An Automatic Verification Method for Data Consistency in Backup and Restoration of Virtual Machines

Abstract

The present invention relates to an automatic verification method for data consistency of virtual machine backup and recovery, which specifically includes the following steps: S1. Prepare a script or use case to be verified; S2. Write a method required for consistency verification, and write a method related to a comparison entry , import the above custom method into the automation tool; S3. Use the backup platform API interface to initiate backup and recovery operations on the CAS platform to verify whether the data is consistent after backup and recovery; S4. Use the verification method and built-in library to call the CAS platform to execute Get, transform, commit to disk, compute MD5 operations. Compared with the prior art, the present invention is suitable for the recovery and verification of virtual machine disk data in the H3C CAS cloud computing management platform, which makes the consistency verification of data after backup and recovery simple in this environment, and saves labor and time. cost, can effectively avoid human error.

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 restoration 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 virtualized image format. It supports snapshot operations and records some internal block allocation information. [0004] The RAW (raw device) format is the original image, which will be directly used as a block device for the virtual machine. It does not suppor...

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
