Abstract

The invention discloses a data verification method, device and storage medium based on multiple checksums. The method includes: reading the data to be verified and the original memory verification from a storage unit of a preset type by acquiring a data reading instruction and, the original memory checksum is generated by the data to be verified; the current memory checksum is generated according to the data to be verified; the original memory checksum is compared with the current memory checksum, according to The comparison result verifies the integrity of the data to be verified. Since the data read in various types of storage units has been verified for data integrity, it is possible to find out whether data errors occur in time.

Description

technical field [0001] The present invention relates to the technical field of data verification, in particular to a multi-checksum-based data verification method, device and storage medium. Background technique [0002] Data integrity refers to the state in which all values ​​stored in a database are correct, the maintenance and assurance of the accuracy and consistency of data throughout its life cycle, and the design, implementation and Use the key. Therefore, maintaining data integrity is the most important responsibility of modern storage systems, and various technologies have been developed and applied to improve data integrity protection. The most commonly used and popular of these is the checksum method. [0003] Checksums are small block benchmarks derived from data blocks to detect errors that may be introduced during their transmission or storage. The traditional checksum method for storage systems is generally end-to-end checksum. When the application program ...
