Abstract

The invention discloses a method for de-repetition selection of repeated data based on cloud computing. The method comprises the steps that at the step S10, when to-be-stored data containing the repeated data is acquired, a load value of a client side and a load value of a server side existing in a storage system at present as well as a current network bandwidth value are acquired; at the step S11, whether the load value of the client side, the load value of the server side and the current network bandwidth value satisfy preset conditions is judged, and the step S12 can be started if the conditions are satisfied; and at the step S12, under a preset de-repetition selection mode, a manner for the de-repetition selection of the repeated data in the to-be-stored data is determined. The load value of the client side, the load value of the server side and the current network bandwidth value greatly influence the selection of the de-repetition manner of the to-be-stored data, so that the three parameters are taken as reference objects, and thus de-repetition efficiency can be increased, and an overall utilization rate of the storage system can be increased. In addition, the invention also discloses a device for the de-repetition selection of the repeated data based on the cloud computing. The device has the same effects.

Description

technical field [0001] The present invention relates to the technical field of cloud computing, in particular to a method and device for deduplication and selection of repeated data based on cloud computing. Background technique [0002] At present, cloud computing is gradually recognized by the industry, and cloud storage systems have gradually played an increasingly important role in social production and life. There are a lot of duplicate data in the cloud storage system, which greatly affects the efficiency of data storage and access, and causes a lot of waste of resources. The data to be stored needs to be deduplicated. For the data to be stored, it is necessary to deduplicate the data. On the one hand, it can effectively save the user's storage space, and can indirectly save the service provider's hardware procurement cost, human energy consumption and equipment room. Use of space, etc.; on the other hand, deduplication does not transmit or store multiple copies of th...
