Problems solved by technology

[0005] In a distributed file system using erasure code storage, storage resources can be greatly saved on the premise of providing the same reliability, but a large number of computing and network resources will be used when erasure code encoding and decoding data, and because the file does not have Multiple copies, so the advantages of concurrent reading and local reading when reading data are not suitable for storing hot data that is frequently read

Abstract

The invention discloses a mixed cloud storage method based on file access frequency. The mixed cloud storage method based on the file access frequency includes the following steps: adopting a multi-copy mode storage strategy for a new file when the new file is uploaded to a file system; adopting an erasure code coding mode storage strategy for the file after the file is completely uploaded to the file system; periodically counting access frequency of each file in the file system, and dividing files into three categories which are respectively high frequency files, medium frequency files and low frequency files; adopting different storage strategies for different types of data and different types of files in the system; and dynamically adjusting the storage strategies of the files according to changes of the access frequency of the files in the system. The mixed cloud storage method based on the file access frequency classifies the files by periodically counting the access frequency of each file in the file system, adopts different storage strategies for different types of files, and adjusts the storage strategies of the files according to the changes of the access frequency of the files, and therefore the whole file system wholly improves system storage resource utilization rate on the premises of guaranteeing data reliability and access speed.

Description

technical field [0001] The invention belongs to the technical field of data storage, and in particular relates to a hybrid cloud storage method based on file access frequency. Background technique [0002] With the continuous development of information technology, cloud storage system occupies a pivotal position. Especially in today's explosive growth of data, it is difficult for local storage to meet the needs of massive data storage. People are increasingly using cloud storage systems, which can bring higher storage capacity, reliability, security and mobility. sex. [0003] The storage distribution mechanism of files in cloud storage system design will affect the specific implementation of many systems. For example, in order to ensure the fault tolerance of the system and the high reliability of data storage, it is necessary to increase storage redundancy; in order to improve the read localization of the system, it is necessary to distribute copies of the same data on m...
