Embodiment Construction

[0011] In order to make the purpose, technical features and implementation effects of the present invention clearer, preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0012] The technical solution provided by the present invention can be applied in the process of local synchronization and remote synchronization; as figure 1 shown, where:

[0013] Local synchronization refers to running the synchronization program on only one electronic device, which is the master device, and another electronic device that does not run the synchronization program is the slave device, and the files to be synchronized on the slave device can be used by the master device through the local drive Or access it through a network share path.

[0014] Remote synchronization refers to the synchronization between the master device as a local device and the remote device through the network. In addition to the master device ne...

Abstract

The invention provides a method and a system for synchronizing data. The method comprises the steps: receiving a synchronous command; generating a first original synchronous policy comprising at least a first file fingerprint; receiving a second file fingerprint included in a second original synchronous policy; comparing if the first file fingerprint and the second file fingerprint are the same; if yes, applying a preset policy change rule to modify the first original synchronous policy and/or the second original synchronous policy so as to generate a first modified synchronous policy and/or a second modified synchronous policy; synchronizing data according to the first modified synchronous policy and/or the second modified synchronous policy. By applying the technology provided by the preferable embodiment of the invention, once the names or positions of files with same fingerprints are changed, the data does not need to be synchronized by networks, and the files can be modified inside equipment, thereby greatly reducing the burden of the networks and enhancing the data synchronizing efficiency.

Description

technical field [0001] The present invention relates to data interaction between different devices, in particular to a data synchronization method and system. Background technique [0002] Between multiple devices, or between a local device and a remote network device, people often need to synchronize or back up files, such as: file synchronization between two computers in the company, file synchronization between a company notebook and a home computer, File synchronization between personal computer and remote data backup center, as well as file synchronization between personal computer and network hard disk. [0003] At present, there are many technical solutions that can solve these synchronization problems. For example, by establishing a file change information table at the synchronization source, and establishing a synchronization rule and a synchronization record table at the synchronization target, after the two are connected, the changes of the synchronization source ...
