Abstract

The invention discloses a data management method and a data storage system. The data storage system comprises a resource pool used for storing multimedia information; a management server used for, when it is determined that first multimedia information meet a preset condition for the first time, sending a first compression instruction for the first multimedia information to a first storage server,so that the first storage server performs compression operation on the first multimedia information according to a compression ratio in the first compression instruction to obtain a compression result, and updates the multimedia information to the compression result; when it is determined that the first multimedia information meets the preset condition for the second time, sending a second compression instruction for the first multimedia information; and when it is determined that the first multimedia information satisfies a predetermined condition for the Nth time, sending an Nth compressioninstruction for the first multimedia information until the ratio of the data volume of the current first multimedia information to the data volume when the first multimedia information is uploaded tothe first storage server is lower than a proportional threshold.

Description

technical field [0001] The present application relates to the technical field of data storage, in particular to a data management method and a data storage system. Background technique [0002] In some scenarios, the data storage system can store a large amount of multimedia information (such as pictures). Due to the limited resources of the cloud storage system, the storage time of multimedia information will be deleted after the predetermined storage time is reached. After the multimedia information is deleted, the user cannot obtain the multimedia information from the data storage system. Therefore, the storage duration of multimedia information needs to be increased without increasing the resources of the data storage system. Contents of the invention [0003] This application proposes a data storage system, which can increase the storage duration of multimedia information without increasing the resources of the data storage system. [0004] According to one aspect ...
