Real-time synchronizing method for file cloud storage

Abstract

The invention discloses a real-time synchronizing method for file cloud storage. The synchronizing method includes the following steps: (1) building a synchronous folder at the client, monitoring change in the synchronous folder, enabling the server to send out a request to the client and synchronizing new files being not synchronized in the synchronous folder to the server; (2) utilizing a client database to record change information in the synchronous folder; (3) enabling a server database to record information of the files synchronized from the client to the server and (4) judging whether files at the server and synchronized into the synchronous folder at the client or files in the synchronous folder at the client are synchronized with the server or not by comparing change information in the synchronous folder and recorded by the client database and information of the files synchronized from the client to the server and recorded by the server database. The method ensures automatic synchronization of files / documents of users at a plurality of computers.

Description

technical field [0001] The invention relates to cloud storage technology, in particular to a real-time synchronization method for file cloud storage. Background technique [0002] U-disk (also known as flash drive, flash drive) is a medium that uses flash memory for data storage, and usually uses a USB plug. Usually, the U disk is extremely small in size, light in weight, hot-swappable and can be rewritten. It has been born for more than 10 years, and it has rapidly become popular and replaced traditional floppy disks and floppy drives after its release. The biggest advantage of U disk is: compact and easy to carry, large storage capacity, and reliable performance. But for consumers, the U disk is a one-shot deal, and they can use as much capacity as they buy. [0003] In the prior art, many people use U disks to store files such as some routinely used programs and work documents so that they can work smoothly on each computer. But it is very inconvenient to use this met...

Problems solved by technology

But it is very inconvenient to use this method to keep the data of multiple computers synchronized. Sometimes a document is modified on a certain computer, but it is forgotten to be copied back to the USB flash drive, and it is not until another computer finds that the document is not the latest.
