Abstract

The present disclosure relates to a sensor network, machine type communication (MTC), machine-to-machine (M2M) communication, and technology for internet of things (IoT). The present disclosure may be applied to intelligent services based on the above technologies, such as smart home, smart building, smart city, smart car, connected car, health care, digital education, smart retail, security and safety services. A method includes acquiring a shared address for at least one file stored at a cloud storage server upon detecting that the at least one file needs to be backed up, determining at least one other cloud storage server to which the at least one file will be backed up, and transmitting a backup request message including the shared address to the at least one other cloud storage server.

First claim

What is claimed is:

1 . A user device in a wireless communication system supporting a cloud storage service, the user device comprising:
a transmitter; a receiver; and at least one processor configured to:
acquire a shared address for at least one file which is stored at a cloud storage server upon detecting that the at least one file needs to be backed up,
determine at least one other cloud storage server to which the at least one file will be backed up, and
control the transmitter to transmit a backup request message comprising the shared address to the at least one other cloud storage server thereby the at least one other cloud storage server backs up the at least one file from the cloud storage server.

2 . The user device of claim 1 , wherein, the at least one processor is further configured to:
control the transmitter to transmit a shared address request message for requesting the shared address for the at least one file to the cloud storage server; and control the receiver to receive a shared address response message comprising the shared address for the at least one file from the cloud storage server.

3 . The user device of claim 1 , wherein, the at least one processor is further configured to generate the shared address for the at least one file.

4 . The user device of claim 1 , wherein, if the number of the at least one file is M, and the number of the at least one other cloud storage server is N, the at least one processor is further configured to one of:
determine the at least one other cloud storage server thereby M/N files will be backed up to each of N other cloud storage servers, determine the at least one other cloud storage server based on an available storage capacity of each of N other cloud storage servers thereby M files will be backed up to the N other cloud storage servers, determine the at least one other cloud storage server based on an available storage capacity of each of N other cloud storage servers and a priority of each of the N other cloud storage servers thereby M files will be backed up to the N other cloud storage servers, determine the at least one other cloud storage server based on an available storage capacity of each of N other cloud storage servers and a file type thereby M files will be backed up to the N other cloud storage servers, and determine the at least one other cloud storage server based on an available storage capacity of each of N other cloud storage servers and a preset preference criterion thereby M files will be backed up to the N other cloud storage servers.

5 . The user device of claim 1 , wherein the at least one processor is further configured to:
control the transmitter to transmit a file state check request message for requesting to check a transmission state for the at least one file to the at least one other cloud storage server after transmitting the backup request message to the at least one other cloud storage server, and control the receiver to receive a file state check response message comprising transmission state information indicating a transmission state for the at least one file from the at least one other cloud storage server.

6 . The user device of claim 1 , wherein the shared address comprises a shared uniform resource locator (URL).

7 . A cloud storage server in a wireless communication system supporting a cloud storage service, the cloud storage server comprising:
a transmitter; and at least one processor configured to:
provide information or a shared address for at least one file which needs to be backed up to a user device, and
control the transmitter to directly transmit the at least one file to at least one other cloud storage server to which the at least one file will be backed up.

8 . The cloud storage server of claim 7 ,
wherein the at least one processor is configured to: control the receiver to receive a shared address request message for requesting the shared address for the at least one file from the user device; and control the transmitter to transmit a shared address response message comprising the shared address for the at least one file to the user device.

9 . The cloud storage server of claim 7 , wherein the at least one processor is configured to:
control the receiver to receive a file list request message for requesting a list for files which the cloud storage server will back up from the user device; and control the transmitter to transmit a file list response message comprising the list for the files which the cloud storage server will back up to the user device.

10 . The cloud storage server of claim 7 , wherein, if the number of the at least one file is M, and the number of the at least one other cloud storage server is N, the at least one processor is further configured to one of:
determine the at least one other cloud storage server thereby M/N files will be backed up to each of N other cloud storage servers, determine the at least one other cloud storage server based on an available storage capacity of each of N other cloud storage servers thereby M files will be backed up to the N other cloud storage servers, determine the at least one other cloud storage server based on an available storage capacity of each of N other cloud storage servers and a priority of each of the N other cloud storage servers thereby M files will be backed up to the N other cloud storage servers, determine the at least one other cloud storage server based on an available storage capacity of each of N other cloud storage servers and a file type thereby M files will be backed up to the N other cloud storage servers, and determine the at least one other cloud storage server based on an available storage capacity of each of N other cloud storage servers and a preset preference criterion thereby M files will be backed up to the N other cloud storage servers.

11 . The cloud storage server of claim 7 , wherein the shared address comprises a shared uniform resource locator (URL).

12 . A cloud storage server in a wireless communication system supporting a cloud storage service, the cloud storage server comprising:
a transmitter; a receiver; and at least one processor configured to:
acquire a shared address of other cloud storage server to which at least one file will be backed up from a user device, and
back up the at least one file from the other cloud storage server using the shared address.

13 . The cloud storage server of claim 12 , wherein the at least one processor is further configured to control a receiver to receive a backup request message comprising the shared address of the other cloud storage server and information on the at least one file from the user device.

14 . The cloud storage server of claim 12 , wherein the at least one processor is further configured to:
control the receiver to receive a file state check request message for requesting to check a transmission state for the at least one file from the user device, and control the transmitter to transmit a file state check response message comprising transmission state information indicating a transmission state for the at least one file to the user device.

15 . The cloud storage server of claim 12 , wherein the shared address comprises a shared uniform resource locator (URL).

16 . A method of a user device in a wireless communication system supporting a cloud storage service, the method comprising:
acquiring a shared address for at least one file which is stored at a cloud storage server upon detecting that the at least one file needs to be backed up; determining at least
