Problems solved by technology

[0004] However, even if a file has been stored on the server, if the user makes a slight change to the file, the Hash value of the entire file will no longer be the same, so the entire file must be stored completely, although most of the content of the file has not changed
In this case, the method in the prior art is no longer applicable, and it actually wastes a large amount of data storage capacity

Abstract

The invention discloses a data storage method of a network cloud storage tool. The method comprises: a client logs in a network cloud storage tool, obtains a data file needing to be stored locally, and uploads a hash value of the file; a cloud storage server determines whether the data file is stored based on the hash value; if so, the client is notified not to carry out uploading and the operation is ended; and if not, the client is notified to upload the data file to the cloud storage server; and the cloud storage server carries out data block division on the data file based on a predetermined algorithm and stores the processed data.

Description

【Technical field】 [0001] The invention belongs to the field of computers and the Internet, and in particular relates to a data storage method of a network cloud disk. 【Background technique】 [0002] In recent years, with the development of the Internet, network cloud disks (referred to as network disks, cloud disks) have become a common data storage service on the Internet. This service is provided by an Internet service provider with large-capacity data storage space. Users can store data at any time. Use the client anywhere to connect to the server provided by the Internet server, upload and download your own data files. [0003] In the prior art, before uploading a file to the network cloud disk, the client first calculates its Hash value, and then uploads the Hash value, and the server judges whether the file has been stored according to the Hash. If it has already been stored, there is no need to upload it repeatedly . This method can find files that are uploaded repe...
