Abstract

A data management method and apparatus of a portable terminal improves memory utilization efficiency using a data move/copy function which allows moving or copying the user data preserved in the non-volatile memory region of the memory of a portable terminal. A data management method for a portable terminal includes selecting at least one user data item in response to a selection request. An extended region for backup of the user data item is checked in response to a backup request. Transfer data corresponding to the user data item is created. The transfer data is stored in the extended region as a backup of the user data item.

Claims

1. A data management method for a portable terminal, comprising:

selecting at least one user data item in response to a selection request;

checking an extended region for backup of the at least one user data item in response to a backup request;

creating transfer data corresponding to the at least one user data item; and

storing the transfer data in the extended region as the backup of the at least one user data item.

2. The data management method of claim 1, wherein the extended region comprises at least one basic region constituting a user data storage region in a memory that is not assigned for storing the at least one user data item.

3. The data management method of claim 2, wherein the extended region further comprises an external region of an external storage medium attached to the portable terminal.

4. The data management method of claim 2, further comprising determining whether to delete the at least one user data item after being backed up.

5. The data management method of claim 4, wherein determining whether to delete the at least one user data item comprises:

deleting, when the backup request is a move request, the at least one user data item from the user data storage region after storing the transfer data in the extended region; and

maintaining, when the backup request is a copy request, the at least one user data item in the user data storage region after storing the transfer data in the extended region.

6. The data management method of claim 2, further comprising searching the basic region assigned for user data for the at least one user data item during a booting process of the portable terminal.

7. The data management method of claim 6, wherein the user data stored in the basic and extended regions and assigned to an identical category are managed in a database form.

8. The data management method of claim 1, further comprising checking available capacity of the extended region before storing the transfer data in the extended region.

9. The data management method of claim 2, wherein the transfer data is identical with the selected at least one user data item in data format.

10. The data management method of claim 3, wherein storing the transfer data comprises saving the transfer data into at least one of the basic regions of the extended region and the external region.

11. The data management method of claim 3, further comprising determining whether the extended region is one of individually separated basic regions or the external region.

12. The data management method of claim 3, wherein storing the transfer data comprises:

checking a category of the at least one user data item;

determining whether a category region corresponding to the category of the at least one user data item exists in the extended region; and

creating the category region in the extended region in response to determining that the category region corresponding to the category of the at least one user data item does not exist in the extended region.

13. The data management method of claim 12, wherein storing the transfer data comprises saving the transfer data into the category region of the extended region as the backup of the at least one user data item in response to determining that the category region exists in the extended region.

14. A data management method for a portable terminal, comprising:

detecting a backup request for backing up user data stored in an internal storage region of the portable terminal;

generating transfer data representing the user data in response to the backup request;

storing the transfer data into one of an internal extended region and an external region as a backup of the user data; and

determining a backup mode of the backup request that indicates one of maintaining the user data in the internal storage region and deleting the user data from the internal storage region after storing the transfer data.

15. The data management method of claim 14, wherein the extended region comprises at least one basic region constituting a user data storage region in a memory that is not assigned for storing the user data.

16. The data management method of claim 14, further comprising:

deleting, when the backup mode of the backup request is a move request, the user data from the internal storage region after storing the transfer data in the extended region; and

maintaining, when the backup mode of the backup request is a copy request, the user data in the internal storage region after storing the transfer data in the extended region.

17. The data management method of claim 14, wherein storing the transfer data comprises:

checking a category of the user data;

determining whether a category region corresponding to the category of the user data exists in the extended region; and

creating the category region in the extended region if the category region corresponding to the category of the user data does not exists in the extended region.

18. The data management method of claim 17, wherein storing the transfer data further comprises saving the transfer data into the category region of the extended region as the back of the user data if the category region exists in the extended region.

19. A portable terminal comprising:

a user interface configured to receive user input;

a memory configured to store user data; and

a controller coupled to the user interface, the display, and the memory, the controller configured to;

detect a backup request from the user input for backing up the user data stored in an internal storage region of the memory,

generate transfer data representing the user data in response to the backup request,

store the transfer data into one of an internal extended region of the memory and an external storage device as a backup of the user data, and

determine a backup mode of the backup request that indicates one of maintaining the user data in the internal storage region and deleting the user data from the internal storage region after storing the transfer data.

20. The portable terminal of claim 19, wherein the controller is further configured to:

delete the user data from the internal storage region after storing the transfer data in the extended region in response to determining that the backup mode of the backup request is a move request; and

maintain the user data in the internal storage region after storing the transfer data in the extended region in response to determining that the backup mode of the backup request is a copy request.
