Abstract

The invention relates to a data backup device based on distributed file data, and the device comprises: a local file storage module which is used for storing local file data; the blocking module that is used for carrying out blocking processing on local file data, respectively carrying out real-time detection on each file data block and determining the change of each file data block; the setting module that is used for setting attribute information of each file data block according to a detection result after the file data blocks are detected in real time in a detection period; and the cloud backup module that is used for storing the backup files of the local file storage module, determining the sequence of updating the backup files based on the attribute information, and realizing unification with local file data. According to the invention, the local file data is subjected to block processing, the change of the formed data blocks is detected, the data blocks which are not modified do not need to be modified, and the corresponding backup modification is carried out through the modified data blocks, so that the backup of mass file data is quicker, and the backup efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of backup storage, in particular to a data backup device based on distributed file data. Background technique [0002] In recent years, with the rapid development of information technology, huge amounts of data have been generated in many application fields such as scientific computing and commercial computing, and the amount of data is still increasing at a relatively rapid rate. The emergence of distributed file systems has solved the problem of how to store and manage these data. As the core basis of cloud storage, distributed file system has become the focus of research in the field of computer applications. Most of the existing mainstream distributed file systems are based on disks, and they provide solutions for the storage of massive data. The emergence of distributed file system solves the storage problem of large-scale data. [0003] In order to protect the files in the distributed file system, it...
