Abstract

A data recovery method and system for a mobile device which is capable of selectively recovering data deleted by a user is provided. The data recovery method of the present invention includes assigning a portion of a memory as a data recovery region, creating recovery lists, each comprising a recovery time and recovery volume, storing data deleted from the memory into the data recovery region on the basis of the recovery lists, displaying the data recovery lists when a data recovery is requested, and recovering the deleted data from the data recovery region when the a data to be recovered is selected from the recovery lists. The data recovery method of the present invention makes it possible to recover the data deleted intentionally or accidentally in the mobile device.

Claims

1. A data recovery method of a mobile device, comprising:

assigning a portion of a memory as a data recovery region;

creating recovery lists comprising a recovery time and a recovery volume;

storing data deleted from the memory into the data recovery region in accordance with the recovery lists;

displaying the recovery lists when a data recovery is requested; and

recovering the deleted data from the data recovery region when the deleted data to be recovered is selected from the recovery lists.

2. The method of claim 1, wherein the data recovery region is assigned in a Transactional File System type-4 (TFS4) region of the memory.

3. The method of claim 2, wherein the TFS4 region comprises:

a first sector for storing operation software; and

a second sector separated from the first sector, wherein the data recovery region is assigned to the second sector.

4. The method of claim 1, wherein the creating of the recovery lists comprises initializing the data recovery region.

5. The method of claim 3, wherein the creating of the recovery lists comprises discarding data which is larger than a capability of the data recovery region in an order of the recovery time.

6. The method of claim 3, wherein the storing of data deleted from the memory comprises permanently erasing the data which is not registered on the recovery lists.

7. The method of claim 3, wherein the recovery lists are sorted by an order of recovery times.

8. The method of claim 3, wherein the recovery lists are sorted by orders of recovery time and data types.

9. The method of claim 3, wherein the recovery lists are sorted by an order of data types.

10. The method of claim 1, wherein the recovery time is determined in at least one of a unit of day, week, and month.

11. The method of claim 10, wherein the recovery volume is limited to a range of a capability of the data recovery region.

12. The method of claim 11, wherein the data recovered from the data recovery region is restored at a region of the memory from which the data was deleted.

20. The data recovery method of claim 1, wherein the recovery time comprises a duration required for recovering at least one item of the list.

13. A data recovery method of a mobile device, comprising:

assigning a portion of a memory as a data recovery region;

creating recovery lists comprising a recovery time and recovery volume;

storing data deleted from the memory into the data recovery region in accordance with the recovery lists; and

recovering the deleted data from the data recovery region when the data to be recovered is selected from the recovery lists.

14. The method of claim 13, wherein the creating of the recovery lists comprises:

configuring recovery times and recovery volumes of the recovery lists; and

designating data to be recovered to the recovery lists.

15. The method of claim 13 further comprising displaying the recovery lists when a data recovery is requested.

16. A data recovery system of a mobile device, comprising:

a keypad for entering key selection information related to a data recovery;

a memory comprising a data recovery region in which recovery lists are stored, wherein the recovery lists are configured with recovery times and recovery volumes and designated data to be recovered;

a controller for storing the data deleted from the memory according to the recovery lists and for restoring the data requested to be recovered to an appropriate region of the memory; and

a display for displaying images related to the data recovery with the recovery lists, under the control of the controller.

17. The system of claim 16, wherein the memory comprises:

a basic region for storing codes, fonts, and parameters of initial settings; and

a file system region for managing data storages, wherein the file system region comprises the data recovery region.

18. The system of claim 17, wherein the file system region comprises an Embedded File System type-2 (EFS2) region and a Transactional File System type-4 (TFS4) region, wherein the TFS4 region comprises the data recovery region.

19. The system of claim 18, wherein the TFS4 region comprises a NAND type flash memory.
