Embodiment Construction

[0060] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0061] In the present invention, the primary and secondary storage volume synchronization data verification method provided by it is mainly based on the method of digest verification algorithm MD5 to calculate the MD5 value in the storage volume for data verification assistance, so that the primary storage volume and the primary storage volume can be quickly verified. The data synchronization problem of the backup storage volume. First, obtain the data of the main storage volume, calculate the MD5 value and save it in text. Then, after the data transfer from the primary storage volume to the backup storage volume is completed, the data of the backup storage volume is obtained, and the MD5 value is calculated and saved in the text. Finally, by comparing the MD5 values ​​of the primary storage volume and the backup sto...

Abstract

The invention relates to the technical field of big data processing. The invention discloses a main and standby storage volume synchronous data verification method. Checking values of data on main andstandby storage volumes are calculated by adopting an abstract checking algorithm; an abstract verification algorithm is adopted when a verification value is calculated after performing slicing and grouping processing on data, then performs calculation of the verification value on an obtained data block, then compares the verification value to determine whether the synchronous data is abnormal, and finally determines whether the synchronous data needs to be backed up again according to a comparison result. The invention further discloses a device and equipment for verifying the synchronous data of the main storage volume and the standby storage volume and a computer readable storage medium. According to the method, the check value is calculated in combination with the MD5 algorithm to realize integrity comparison of the data in the main and standby storage volumes; compared with the prior art, the time length of data comparison is greatly saved, comparison and updating of part of datacan be carried out, the standby storage volume can be kept synchronous and identical with the data of the main storage volume in real time, and data loss of the main storage volume is avoided.

Description

technical field [0001] The present invention relates to the technical field of big data processing, and in particular to a method, device, equipment, and computer-readable storage medium for verifying synchronous data of primary and backup storage volumes. Background technique [0002] With the popularization of storage system applications, especially for enterprises or individual users to store big data or build server systems, it is widely used, but for different user groups, its security performance and data protection of storage systems There will be different requirements for protection performance; especially now there are more and more systems consisting of primary and secondary storage volumes. The primary storage volume has the highest data and update frequency in the storage system and is also the main storage unit. The volume is used for backup of the primary storage volume. When the storage system fails, the data can be restored through the backup storage volume....
