Embodiment Construction

[0015] The method of the invention divides the data storage area into: data area, copy area and coding area. The data area is used to store source data, that is, the area where data is stored when the data enters the storage platform for the first time; the copy area is used to store copy data, that is, when a certain data is stored in the data area, it is immediately copied in the copy area The method stores a copy of the data; the copy area and the data area constitute an HDFS system implementing a dynamic copy strategy (multi-copy full backup disaster recovery system); the coding area is used to form a complete information-associated disaster recovery system with the data area .

[0016] In this method, the copy area and the data area constitute a multi-copy full backup disaster recovery system implementing a dynamic copy strategy. Every time data is written, the original data is first written into the data area, and then the system automatically copies the data by using t...

Abstract

The invention discloses a mass data distributed storage method. A data storage area is divided into a data area, a copy area and a coding area; the data area is used for storing source data; the copy area is used for storing copy data; the copy area and the data area form a multi-copy full backup disaster recovery system; the coding area and the data area form a complete information association disaster recovery system. Compared with the prior art, the invention is advantaged by that on the basis of mass data storage cost, efficiency and load equalization, a new method combined with a data information association strategy and a dynamic copy strategy is proposed; the cluster data security is ensured, at the same time, the data recovery speed of the system is remarkably improved, the load equalization capability of the system is optimized, and the integrated storage cost of the system is reduced.

Description

technical field [0001] The invention relates to a method for distributed storage of massive data. Background technique [0002] The rapid development of Internet technology, the popularization of information equipment, and the extensive application of information technology by enterprises and individuals have promoted the large-scale growth of data. If in the past data was mainly generated and utilized by business departments, now it is all people who create and share data. Data is becoming ubiquitous and affecting the business of enterprises and everyone's life in every possible way. The society has entered the era of big data (bigdata). [0003] The crazy growth of data has also brought new challenges to the traditional data storage model: while the disk capacity is increasing rapidly, its access speed has not been significantly improved. For massive data processing tasks, Google took the lead in designing and implementing a new distributed file system GFS (Google File S...
