Embodiment Construction

[0048] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0049] figure 1 It shows the implementation flowchart of the database snapshot verification method provided by the present invention, which specifically includes the following steps:

[0050] In step S101, according to the pre-built snapshot creation environment, the first target on-disk data and the second target on-disk data corresponding to the first time point and the second time are generated, and the data on the first target on-disk The corresponding first snapshot and the second snapshot corresponding to the data in the second target disk.

[0051] In step S102 , the control executes the r...

Abstract

The invention relates to the technical field of storage, and provides a database snapshot verification method and system. The method comprises the following steps of according prebuilt snapshot creation environment, generating data in a first target disk corresponding to the first time point, data in a second target disk corresponding to the second time, a first snapshot corresponding to the datain the first target disk, and a second snapshot corresponding to the data in the second target disk; controlling the execution of a back rolling operation; performing comparison judgment on the snapshot of the corresponding time point obtained by the back rolling operation with the pre-generated snapshot of the corresponding time point and the data in the target disk; when the judging result is the matched condition, the database snapshot function is judged to be normal; when the judging result is the unmatched condition, the database snapshot function is judged to be abnormal, so that the detection verification on the authenticity and completeness of the snapshot is realized; and the blank of the snapshot verification based on the field of the database is filled.

Description

technical field [0001] The invention belongs to the technical field of storage, and in particular relates to a database snapshot verification method and system. Background technique [0002] With the advent of the era of big data, data has become the most important wealth of enterprises, institutions and individuals. Data centralization has become the general trend, and more and more enterprises choose to build their own (cloud) storage systems, or directly migrate data to the cloud. At present, online data backup and recovery through snapshots has become an indispensable function of online systems, and is favored by manufacturers and customers. [0003] When an application failure or file damage occurs on a storage device, fast data recovery can be performed, and the data can be restored to the state at a certain available point in time. Another function of snapshots is to provide another data access channel for storage users. When the original data is processed by online...
