Automatic verification method for volume real-time protection data

Abstract

The invention discloses an automatic verification method for volume real-time protection data, includes the steps of automatically verifying the consistency status of backup data generated by volume real-time protection through policies, the system log, the service status, the database query, etc. to judge the integrity of the mapped system disk view and data disk view data so as to ensure the availability of the backup data generated by volume real-time protection after recovery, find the problems of the backup data in time, reduce the technical requirements and labor costs of the existing manual drill verification, and increase the frequency of drill verification. The invention directly performs data verification in a production environment shadow system, and the verification items are more comprehensive and credibility is high.

Description

technical field [0001] The invention relates to the technical field of data protection and disaster recovery, in particular to an automatic verification method for volume real-time protection data. Background technique [0002] In recent years, the technology of granular protection of data volumes has become a trend of data disaster recovery. It monitors and intercepts all IO operations of volumes by installing volume filter drivers on production servers, and forms IO log records with time stamps. And save to the backup storage, has the following advantages: first, this method has nothing to do with the file type and data type; The backup data is generated and mounted in a volume view. After mounting, it can temporarily replace the production disk volume, and can also restore files at a granular level. [0003] For the backup data generated by the real-time protection of the above volumes, there are generally two methods to verify the backup data: [0004] Method 1. Accord...

AI Technical Summary

Problems solved by technology

[0007] (1) Manually performing data recovery drills will increase personnel costs for enterprises or units, and the technical requirements for operators are relatively high. They need to be familiar with the disaster recovery system and the application system of the production server

Usually, enterprises or units do not have such professionals, and if they purchase services from disaster recovery vendors, additional costs will be incurred

[0008] (2) The number of manual data recovery drills is limited, and due to lack of supervision, this work will be forgotten, resulting in incomplete backup data that cannot be discovered in time

[0009] The second method above, through the backup server program module to perform regular checksum calculation, can ensure the integrity of the backup data and avoid the unrecoverable backup data caused by the damage of the backup storage system, but it is impossible to find out whether the IO operation monitoring and interception are complete. Therefore, there is still the possibility that the backup data recovery is not available
