Abstract

The invention provides a data storage method. The method comprises the steps of judging whether a fingerprint value exists in local storage or not when the fingerprint value of to-be-stored data is received; if yes, storing the to-be-stored data into an independent storage area; judging whether the to-be-stored data is the same as stored data corresponding to the fingerprint value in the local storage or not; if yes, deleting the to-be-stored data from the independent storage area; and if not, transferring the to-be-stored data from the independent storage area to the local storage. Accordingto the method, the problem of data mistaken deletion possibly caused by hash conflicts is solved by utilizing the independent storage area, and the data storage consistency is ensured. The invention further provides a data storage system, a computer readable storage medium and a server, which have the above beneficial effects.

Description

technical field [0001] The present application relates to the field of data storage, in particular to a data storage method, system and related devices. Background technique [0002] In the field of storage, massive data query and storage require huge resources, seriously affecting the performance of data storage. In these data, there are a lot of duplicate data. In order to reduce the resources occupied by the stored data and improve the performance of data storage, only one copy of this duplicate data can be saved in the storage medium. The amount of data storage. The method of judging whether the data is repeated is to calculate the data fingerprint value through the hash algorithm, and compare the fingerprint value as the basis for whether the data is the same. However, there is a hash conflict in the hash algorithm, that is, different data get the same hash value through the hash operation. [0003] Therefore, how to solve the impact on data storage due to hash colli...
