Problems solved by technology

In the face of ever-increasing data storage pressure, most storage systems can only deal with this problem by increasing storage capacity.
[0003] However, there are only two ways to increase storage capacity. One is to add more disks to the storage system, and the other is to replace disks with high-capacity versions. However, this method is not only limited by disk technology, but also increases the economic It also increases the difficulty of disk management by the storage system

Abstract

The application provides a file processing method, and provides a novel data storage mode which mainly depends on fingerprint database and file information database to realize data storage. the data fingerprint database and the file information database are associated through the data fingerprint, based on this, when a file needs to be stored, the file is divided into low-latitude chunks of data,then whether the same data has been stored in the storage system based on the data blocks is judged, so that the same data is not stored repeatedly. The invention only needs to record the correlationbetween the file and the data block in the file information base, so that the space occupied by the duplicate file or similar file in the storage system can be greatly reduced, the storage resources are saved, and the utilization ratio of the storage space is provided to relieve the pressure of the large data storage. In addition, the present application also provides the corresponding devices andapparatuses.

Description

technical field [0001] The present application relates to the technical field of data access, and in particular to a file processing method, device and equipment. Background technique [0002] With the development and popularization of big data technology, all walks of life are facing the pressure of big data storage. In the face of ever-increasing data storage pressure, most storage systems can only deal with this problem by increasing storage capacity. [0003] However, there are only two ways to increase storage capacity. One is to add more disks to the storage system, and the other is to replace disks with high-capacity versions. However, this method is not only limited by disk technology, but also increases the economic It also increases the difficulty of disk management by the storage system. [0004] Therefore, there is an urgent need to provide a file processing method that can alleviate the pressure of big data storage without increasing the cost of hardware, so a...
