Problems solved by technology

An obvious disadvantage of this technical solution is that even if only one byte in the file is updated, the entire file must be transmitted, resulting in a large unnecessary consumption of time and network resources
The obvious disadvantages of this technical solution are: the hash operation will consume a lot of CPU resources, and the transmission of a large number of data block contents and locations will consume too many network resources

Abstract

The invention relates to the technical field of the synchronization of data or files, in particular to a method and a system for implementing data synchronization by using string matching. The invention provides the method for implementing data synchronization, comprising the following steps of: obtaining an old copy and a new copy of the data to be synchronized in a source node; determining the difference between the old copy and the new copy by using character string matching so as to generate a block diagram; and sending the generated block diagram to a target node so as to synchronize the old copy of the data to be synchronized of the target node to the new copy of the data.

Description

technical field [0001] The invention relates to the technical field of data or file synchronization. More specifically, the present invention relates to a method and system for data synchronization using a string matching algorithm. Background technique [0002] Currently, more and more applications have data or files stored on different computers, and it is necessary to ensure that when the data or files are updated on one of the computer nodes, these updates can be synchronized on other computers. Typically, the original computer or computing node where the data update occurs is called the source node, and the other computer or computing node to be synchronized is called the target node. Further, such data synchronization requirements are more urgent in the cloud computing (Cloud Computing) environment, for example, in the cloud storage (Cloud Storage) environment, data and files are redundantly distributed on multiple different nodes, requiring data synchronization techn...
