Abstract

In a method for storing data files to cloud servers using a cloud computing device, the cloud computing device connects to at least one terminal device through a network. The cloud computing device receives one or more data files from the terminal device, and determines a file storing mode of each of the data files. The cloud computing device generates a file information list of the data files according to the file storing modes of the data files, and search the cloud servers in the network according to the file information list. The cloud computing device divides each of the data files into data blocks according to the file information list, uploads each of the data blocks to the cloud servers according to the file storing locations, and stores the file information list in a storage device of the cloud computing device.

store the file information list in the storage device of the cloud computing device.

2. The cloud computing device according to claim 1, wherein the program instructions further cause the at least one processor to:

determine whether all the data blocks of the data files have been uploaded to the cloud servers; and

send a successful message indicating that the data files have been stored in the cloud servers successfully when all the data blocks of the data files have been uploaded to the cloud servers.

3. The cloud computing device according to claim 1, wherein the program instructions further cause the at least one processor to:

receive a file downloading command from the terminal device for downloading a data file from the cloud servers;

obtain a file storing location of each data block of the data file from the file information list stored in the storage device;

download each data block of the data file from the cloud servers according to the file storing location of each data block stored in the file information list; and

combine all the downloaded data blocks to generate the data file, and send the data file to the terminal device.

4. The cloud computing device according to claim 3, wherein the program instructions further cause the at least one processor to:

check the file information list to determine whether the data file exists in the cloud servers;

generate a failure message indicating that the data file does not exist in the cloud servers when the data file does not exist in the cloud servers; and

sends the failure message to the terminal device for informing the user that no data file is found in the cloud servers.

5. The cloud computing device according to claim 1, wherein the file information list comprises a file name of each of the data files, information on the data blocks of each of the data files, and the storing location of each of the data blocks that need to be stored in the cloud servers.

6. The cloud computing device according to claim 5, wherein the data blocks of each of the data files are randomly stored in the cloud servers.

7. The cloud computing device according to claim 1, wherein each of the data files is a text file, an image file, or a multimedia data file including audio data and video data.

8. A method implemented by a cloud computing device, the cloud computing device being connected to at least one terminal device and a plurality of cloud servers through a network, the method comprising:

receiving one or more data files from the terminal device, and determining a file storing mode of each of the data files;

generating a file information list of the data files according to the file storing mode of each of the data files;

searching one or more cloud servers in the network according to the file information list, and creating a data transmission channel between the cloud computing device and each of the searched cloud servers;

dividing each of the data files into a plurality of data blocks according to the file information list;

uploading each of the data blocks to the searched cloud servers through the data transmission channels according to a file storing location of each of the data blocks stored in the file information list; and

storing the file information list in a storage device of the cloud computing device.

9. The method according to claim 8, further comprising:

determining whether all the data blocks of the data files have been uploaded to the cloud servers; and
