Abstract

The invention discloses a data storage method and apparatus. The method comprises the following steps: grouping file storage areas, and setting storage capacity of each group; receiving a file uploading request sent by a client, wherein the file uploading request comprises a file identifier of a to-be-uploaded file and a check block of the to-be-uploaded file calculated according to a preset algorithm; determining the information of the to-be-uploaded file, wherein the information comprises the file identifier of the to-be-uploaded file, and the original data and the check block of the to-be-uploaded file; determining a target group comprising: determining the file identification range of the group, and using the group in which the file identification range contains the group of the file identifier of the to-be-uploaded file and the residual storage capacity is not smaller than the storage amount occupied by the information of the to-be-uploaded file as the target group according to the file identifier of the to-be-uploaded file and the file identification range of the group; and storing the information of the to-be-uploaded file in the target group. By adoption of the data storagemethod and apparatus, the scientificalness of the file management can be improved, and the storage speed is improved.

Description

technical field [0001] The present invention relates to the field of cloud storage, in particular to a data storage method and device. Background technique [0002] Existing distributed data storage systems generally use fixed data copies (such as 2 copies or 3 copies), and its main disadvantage is that for cold data stored in the data storage area with fewer access times, it also needs to occupy multiple copies of storage space. This makes it impossible to free up more storage space for hot data stored in the data storage node with a large number of visits, resulting in a low effective utilization of the storage space. [0003] In order to save the storage space occupied by cold data, in the prior art, an erasure coding (Erasure Coding) algorithm is used to encode the file content. When the file content is damaged, the code can be used to restore the file content, which reduces the cold data due to The storage space occupied by the store replica. [0004] When a user down...
