Abstract

A method, system, and computer program product for backing up data from a wireless device onto a server via a network is provided. In one embodiment, a backup server, responsive to a determination that data from a wireless device should be backed up, initiates a backup process. The backup process may be initiating, for example, by pushing a request to the wireless client via a proxy/gateway server requesting that the client transmit data to be backed up to the backup server. A determination as to when to backup may be made, for example, in response to an indication that the wireless device has been powered on or in response to a determination that a predetermined amount of time has elapsed since the last backup was performed. The backup server then receives the data from the wireless device and stores the data on a storage device connected to the network for later retrieval such that if the wireless device loses its data, the data can be retrieved from the backup server and reloaded onto the wireless device. The backed up data may be, for example, phone lists, calendars, address lists, or notes.

Claims

2. The method as recited in claim 1, wherein the connection is established in response to receipt of an indication that the wireless device has been powered on.

3. The method as recited in claim 1, wherein connection is established periodically.

4. The method as recited in claim 1, wherein the connection is established in response to receipt of a request to backup data from the wireless device.

5. The method as recited in claim 1, wherein the step of pushing the request comprises sending a textual based service load to a proxy server, wherein the proxy server is configured to translate textual based service loads to binary based service loads and send the translated service load to the wireless device.

6. The method as recited in claim 5, wherein the service load provides a uniform resource identifier for an application that the wireless device may retrieve to transmit the data to the server.

7. The method as recited in claim 1, wherein the data includes at least one of phone lists, calendars, address lists and note.

8. The method as recited in claim 1, wherein the connection between the server and the wireless device uses unused extra bandwidth.

10. The method as recited in claim 9, wherein the request is a textual based service load providing the client with a uniform resource identifier for an application which will identify, locate, and transmit the requested data to the backup server.

11. The method as recited in claim 9, wherein the translated request is a binary based service load.

12. The method as recited in claim 10, wherein the third protocol is a wireless application protocol.

13. The method as recited in claim 10, wherein the fourth protocol is a hypertext transfer protocol.

15. The method as recited in claim 14, wherein the data to be backed up is sent to the server by way of a proxy server and is sent using a wireless application protocol.

16. The method as recited in claim 14, further comprising:

transmitting a request to the backup server via the wireless network to retrieve backed up data;

receiving the backed up data from the backup server via the wireless network; and

21. The computer program product as recited in claim 18, wherein the connection is established in response to a request to backup data received from the wireless device.

22. The computer program product as recited in claim 18, wherein the second instructions comprise instructions enabling the transmission of a textual based service load to a proxy server, wherein the proxy server is configured to translate textual based service loads to binary based service loads and send the translated service load to the wireless device.

23. The computer program product as recited in claim 22, wherein the service load provides a uniform resource identifier for an application that the wireless device may retrieve to transmit the data to the server.

28. The system as recited in claim 27, wherein the connection is established in response to receipt of an indication that the wireless device has been powered on.

29. The system as recited in claim 27, wherein the connection is established periodically.

30. The system as recited in claim 27, wherein the connection is established in response to a request to backup data received from the wireless device.
