Problems solved by technology

It can conveniently and efficiently synchronize updated files from the cloud server to the playback terminal. However, the remote resource synchronization method and system of the three-tier architecture only completes data comparison once, and the calculation and processing of large scores are still completed in the cloud, which is highly dependent on the network. Fundamentally solve the service load on the cloud

Embodiment 1

[0044] Such as Figure 1-2, the present invention a kind of cloud-local file synchronous realization method, comprises the following steps:

[0045] Step S1, the application client sends the file list information of the designated synchronization folder to the background for comparison with the pre-uploaded file list information, and stores the uploaded file information in the background in the local database of the application client.

[0046] Scanning the file list of the designated synchronization folder and the pre-uploaded file list to calculate the check code of the file list information of the designated directory and the check code of the file list information of the pre-uploaded file.

[0047] The user installs the cloud storage application client, edits the file list of the specified synchronization folder and sends it to the application client, and the application client scans the file list of the specified synchronization folder sent by the user and the list of pre...

Embodiment 2

[0070] Such as Figure 3-5 , a cloud-local file synchronization system of the present invention, comprising:

[0071] The first comparison module compares the newly uploaded file list information of the designated synchronization folder with the pre-uploaded file list information.

[0072] Before the first comparison module, there is also a receiving module, which is used for the background application client to send the specified synchronization folder file list information.

[0073] The storage module stores the uploaded background file information in the local database of the application client according to the comparison result of the first comparison module.

[0074] The user installs the cloud storage application client, edits the specified synchronization folder file list and sends it to the application client, and the application client receives the specified synchronization folder file list sent by the user and sends it to the cloud. Scan the specified synchronizati...

Embodiment 3

[0088]The difference from Embodiment 1 is that in this embodiment, the secure hash algorithm (SHA1) is used for file scanning calculations, which is safer and more accurate than MD5. SHA1 will generate a 160-bit message digest, while MD5 is to generate a 128-bit hash value.

Abstract

The invention discloses a cloud-local file synchronization implementing method and a cloud-local file synchronization implementing system, and belongs to the technical field of file synchronization. The method provided by the invention comprises the steps as follows: S1, an application client sends synchronization folder file list information to background and compares the information with pre-loaded file list information, and stores the file information has uploaded to the background into a local database of the application client; and S2, the local file list information is acquired and compared with the local database list information, if the local database list information does not include the local file list information, difference file information acquired after comparison is uploaded to the cloud for updating, if the local database list information comprises the file information not existing in the local file list information, the file is deleted in the cloud, and if the local database list information is completely the same as the local file list information, no synchronization operation is performed in the cloud.

Description

technical field [0001] The present invention relates to the technical field of file synchronization, in particular to a cloud-local file synchronization method and system. Background technique [0002] At present, Internet services are extremely popular, and cloud storage services are developing rapidly. Both individuals and enterprises are red sea users of cloud storage services. A locally implemented and highly efficient method for comparing files that need to be synchronized locally can bring great convenience to users. [0003] Cloud storage refers to a system that integrates various types of storage devices in the network through application software to work together through functions such as cluster applications, grid technology, or distributed file systems, and jointly provide data storage and business access functions to the outside world. The structure of the existing online cloud storage system is as follows: figure 1 As shown, it consists of two parts, the clien...
