Problems solved by technology

[0004] (1) Single redundancy method
At present, the multi-cloud storage methods on the market mostly use a single method to make data redundant, that is, only use the copy strategy or only use the erasure code technology, and these two technologies have their own advantages and disadvantages
Even though some cloud storage methods use hybrid redundancy technology for data storage, the judgment criteria are relatively simple and cannot reflect the actual user's access requirements for data.
[0005] (2) The problem of not looking at hot and cold data from the perspective of time correlation

Abstract

The invention discloses a cloud storage method, which comprises the following steps: judging whether a data block in a file to be stored is stored for the first time, wherein the file to be stored comprises a plurality of data blocks partitioned in advance; when the data block of the file to be stored is stored for the first time, determining the cold and hot degree of the data block of the file to be stored according to the access frequency; when the data block of the file to be stored is not stored for the first time, determining the cooling and heating degree of the data block of the file to be stored according to the reference amount; a storage policy of a data block of the file to be stored being determined according to the degree of heat and cold, and the data block of the file to bestored being stored according to the storage policy. The invention also discloses a cloud storage system and a cloud storage device. By adopting the embodiment of the invention, the first and non-first stored data blocks can be judged according to their properties, and the degree of cooling and heating of the data can be judged according to the time correlation.

Description

technical field [0001] The present invention relates to the technical field of cloud storage, in particular to a cloud storage method, system and equipment. Background technique [0002] With the rapid development of information technology, the amount of data is growing explosively. At present, we have entered the era of PB-level data volume. The sudden increase of data requires the rapid improvement of storage technology and the substantial reduction of the cost of storage equipment. Under this series of trends, cloud storage methods with distributed characteristics emerge as the times require. However, cloud storage inevitably produces the problem of service termination or loss due to the effectiveness of the server. Therefore, how to reduce space consumption while ensuring fault tolerance has become an important direction of cloud storage research. The copy strategy is an earlier data redundancy technology, which has the advantage of supporting high concurrent access, ...
