Embodiment Construction

[0046] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0047] The main solution of the present invention is: when receiving a data read request, determine the read check code corresponding to each data block corresponding to the data read request according to the data blocks stored in the data storage area; The mapping relationship between the check code stored in the information storage area and the data block determines the storage check code of each data block; when the read check code matches the corresponding storage check code, from the data storage area Read the data block corresponding to the data read request.

[0048] The current data verification scheme is to store the storage data block and the corresponding storage verification code together in the data storage area. When reading the storage data block through the physical address, as long as the read verificat...

Abstract

The invention discloses a data storage and verification method based on duplication elimination, and the method comprises the following steps: determining a reading verification code corresponding toeach data block needing to be read corresponding to a data reading request according to the data blocks stored in a data storage region when the data reading request is received, determining a storageverification code of each data block according to a mapping relationship between the verification code stored in the information storage region and the data block, and when the reading verification code is matched with the corresponding storage verification code, reading the data block corresponding to the data reading request from the data storage region. The invention further discloses a data verification device and a computer readable storage medium. By separately storing the data and the verification code, the effective space of data storage is increased, the accuracy of data verificationcan be improved, and the problem of check errors caused by address information errors is avoided.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a deduplication-based data storage and verification method, a data verification device and a computer-readable storage medium. Background technique [0002] With the development of the digital age, the application of big data has experienced explosive growth, and as the amount of data continues to increase, data deduplication technology is increasingly valued by data storage manufacturers, and data storage systems and data application clients The data consistency among them has become the key to measure the quality of storage. [0003] When reading data, the traditional data verification method is to first calculate the cyclic redundancy check code information of each sector, and then send the data and the check code to the disk together. Since the data and the check code are stored together, in some cases (such as a software problem), when the physical address of the da...
