Embodiment 1
[0019] see figure 1 , which is a flowchart of a method for managing files in a cloud storage system in an embodiment of the present invention, and the specific steps are as follows:
[0020] Step 101, the cloud server receives the file to be stored.
[0021] In the embodiment of the present invention, the cloud server can receive the file to be stored from the user terminal, and the file can be a backup file, such as the backup address book of the user terminal, the system file of the backup user terminal, etc., and the file can also be It is shared files, such as shared application files, shared audio and video files, etc. The above-mentioned user terminal may be terminal equipment such as a computer, a mobile phone, and a tablet computer.
[0022] Step 102, the cloud server divides the file to be stored into multiple sub-files.
[0023] That is, the file to be stored is divided into two sub-files by the cloud server, or at least three sub-files, for example, the file A to...
Embodiment 2
[0049] see figure 2 , is a schematic structural diagram of a cloud storage system in an embodiment of the present invention, the cloud storage system includes a cloud server 21 and a cloud storage server group 22, wherein
[0050] The cloud storage server group 22 includes at least two cloud storage servers 221, and the cloud storage servers 221 are used to store sub-files;
[0051] The cloud server 21 is used to divide the file to be stored into multiple sub-files, and repeatedly save each sub-file in the multiple sub-files to different cloud storage servers 221 in the cloud storage server group 21; when receiving After the request for downloading the file, multiple sub-files related to the file are obtained from the cloud storage server group 21, and a file is generated according to the multiple sub-files.
Embodiment 3
[0053] see image 3 , is a schematic structural diagram of the cloud server in an embodiment of the present invention, and the cloud server 21 includes:
[0054] File division module 211, for dividing the file to be stored into a plurality of sub-files;
[0055] The sub-file processing module 212 is used to repeatedly save each sub-file in the multiple sub-files to different cloud storage servers in the cloud storage server group;
[0056] The file generating module 213 is configured to obtain multiple sub-files related to the file from the cloud storage server group after receiving the request for downloading the file, and generate the file according to the multiple sub-files.
[0057] In another embodiment of the present invention, the sub-file processing module 212 is further configured to sequentially select at least two sub-files from a plurality of sub-files, and save each sub-file at least once, and store the sequentially selected at least two sub-files respectively S...
