Abstract

The invention provides a data storage method and device based on a redundancy mechanism and a server. At the server side, the method comprises the steps that the state of a data file is checked according to a preset period, and a cold data file with an access rate smaller than a first preset access rate threshold is found; the cold data file is fragmented according to a preset data fragmentation backup fault-tolerant algorithm, and all data fragments are stored into different storage nodes; the cold data file is deleted; and storage node information of all the data fragments is recorded. According to the method, the data file with a low access rate is fragmented and stored by use of the data fragmentation backup fault-tolerant algorithm (e.g., an IDA data fragmentation algorithm), and a certain storage space can be saved on the premise of guaranteeing data security and integrity.

Description

technical field [0001] The present application relates to the technical field of network data storage and service, in particular, to a data storage method and device based on a redundancy mechanism, and a server. Background technique [0002] Most of the current distributed file systems use the redundancy of the complete copy method. This method only needs to have one copy to provide services safely, but its disadvantage is that the utilization rate of storage space is low. For some files with extremely low access rates, Full storage and full backup waste a certain amount of storage space. Contents of the invention [0003] The present application provides a data storage method, device, and server based on a redundancy mechanism, which are used to solve the problem of wasting storage space caused by full data backup in order to ensure safety and integrity in the prior art. [0004] A data storage method based on a redundancy mechanism disclosed in the present application....
