Data deduplication management device, system and method and storage medium

The invention discloses a data deduplication management device, which comprises a data detection module used for acquiring an encrypted file C, performing data duplication detection on the encrypted file C, generating two-tuple data according to related data of the encrypted file C when data duplication is detected, and sending the two-tuple data to a prediction module; wherein the AMO represents a file scale identifier, and the D (OS) represents the scheduling condition of the current operation of the cloud server; the prediction module is used for receiving a network TW and two-tuple data generated by pre-training, inputting the network TW and the two-tuple data into the predictor P, outputting a scheduling strategy S generated by the predictor P, a current server busy level M and an ideal operation state N, and forming three-tuple data; and the de-duplication operation module is used for generating operation sequence information according to the triple data, scheduling the cloud server process and performi
