Problems solved by technology

However, in the method of storing data on the network disk, the administrator of the network disk has the authority to manage the data stored by the user. The administrator of the network disk can query the data stored by the user, even delete the stored content or freeze the account of the network disk, which affects the security of data storage.

Embodiment 1

[0031] The data storage method in this embodiment is implemented by a device with a storage function, such as a computer. In this embodiment, a computer is used as an example to illustrate the data storage method, but the data storage method in this embodiment is not limited to a computer.

[0032] Such as figure 1 As shown, the data storage method includes:

[0033] Step 11: Divide the local encrypted disk according to user settings, and the local encrypted disk is an independent data storage space.

[0034] In this embodiment, according to user settings, part of the storage space in the storage device of the computer is divided as a local encrypted disk for storing local encrypted data.

[0035] In order to realize that the encrypted disk on the computer can actively ensure the security of the stored content, the access password of the encrypted disk can be set in this embodiment, and a secure login mechanism can also be adopted at the same time. Users need to log in to ac...

Embodiment 2

[0083] Such as figure 2 As shown, this embodiment provides a computer system, and the data storage method provided by this embodiment can be applied to the computer system.

[0084] The computer system includes 4 types of devices interconnected through the Internet, namely core storage device S1, storage server S2, computer S3, and mobile device S4. Among them, the core storage device S1 is used for storing user information, index information of user files, etc., and can also assist in establishing a P2P link. Setting up multiple core servers S1 in this system can provide more powerful dispatching capability on the one hand, and is also for load balancing and disaster backup on the other hand.

[0085] The storage server S2 is reserved to avoid the situation that there are not enough other active users on the current link to establish P2P connections to synchronize data when users store data synchronously. Its function and function are equivalent to that of an ordinary user ...

Embodiment 3

[0091] In the data storage method of this embodiment, the actual usage of the storage capacity of any local encrypted disk is as follows image 3 shown. The storage space allocated by local users is defined as a local encrypted disk. In the local encrypted disk, the used space refers to the space that the user can no longer write data into, and the available space of the local user refers to the maximum capacity of the local user to write data into the encrypted disk. The used space includes both the encrypted data of the local user and the encrypted data synchronously stored by other users on the network. The synchronous storage of encrypted data of other users runs automatically in the background, which can be transparent to local users, and reminders for local users can also be set.

[0092] Therefore, the local encrypted disk not only stores local encrypted data, but also stores backup data from other users in the network link. Preferably, the backup data of these other...

Abstract

The present invention discloses a data storage method, which is applied to a data storage system. The system comprises a server and at least one computer. The method comprises: a first computer dividing a local encrypted disk according to use setting, wherein the local encrypted disk is an independent data storage space; encrypting data currently stored by a user into the local encrypted disk, so as to obtain first encrypted data; sending the first encrypted data to the server; synchronously storing the data into an encrypted disk of at least one other computer, wherein the encrypted disk of the at least one other computer is divided in advance; when the first computer receives an instruction of deleting data, the first computer querying the server for information of a computer that stores the data; and when the number of the computer that stores the data is smaller than a preset number, the first computer synchronously storing the data into the at least one other computer.

Description

technical field [0001] The invention relates to the field of computers, in particular to a data storage method. Background technique [0002] A network disk can be understood as a hard disk or U disk stored on the network, so the network disk is also called a network U disk or a network hard disk, and is used to provide users with online file storage, access, backup, sharing and other file management functions. Through the network disk, no matter where the user is, as long as he can connect to the Internet, he can manage the files stored online in the network disk through the mobile terminal. [0003] There are many existing network disk storage methods. For example, the file upload method of the network hard disk provided by the application file with the application number 201210362185.1 stores the file according to the file summary; another example, the application file with the application number 201280000563.X provides The network disk file storage method, according to ...
