A method and apparatus for data synchronization based on a distributed file system

Abstract

The invention relates to a data synchronization method and a device based on a distributed file system, At that same time, communication interactions are performed with the physical server and the virtual server through a data server by adopting a dual-server working mode, A memory cluster and a metadata cluster based on a database are established, data are written into the temporary data block according to the received signal difference, and the contents of the temporary data block replace the file contents in the original data node to realize data synchronization. The invention adopts the working mode of interactive communication between the physical server and the virtual server and the double servers, wherein the two servers are respectively responsible for their respective functions and switched to the single server working mode under necessary conditions, thereby effectively ensuring the running efficiency of the system. At the same time, the database based on memory clusters andmetadata clusters for data synchronization content clustering, treated separately, effectively ensure the rational allocation of data synchronization resources and data synchronization accuracy.

Description

technical field [0001] The present application belongs to the technical field of distributed processing, and in particular relates to a data synchronization method and device based on a distributed file system. Background technique [0002] With the continuous improvement of people's quality of life, the application of the Internet is also constantly popularized. In order to provide us with more convenient services, the application of the Internet is also constantly developing and evolving. Constantly increasing. Among the many network security problems, the accidental deletion of files leads to the change or loss of important information is the most serious. For this reason, domestic and foreign websites are constantly researching on the anti-accidental deletion technology of web pages. [0003] In the initial stage of webpage anti-tampering system, its internal structure is very simple, and the division of functional modules is also less. Although it can solve some basi...
