Abstract

A system and method are provided for implementing conflict resolution in a sync manager. In case of a conflict, the sync operation creates and stores a conflict object, and resumes the sync operation without requiring user input. The sync operation can thus be completed without user input and the user may choose to resolve outstanding conflicts, either on-line or off-line, at a convenient time. Furthermore, the invention provides a platform for developing standardized, user-friendly sync operations. In addition, the invention presents a centralized location that allows a user to quickly and easily resolve conflicts originating from many devices.

Claims

1. A method for performing a sync operation, the method comprising:

receiving a first file;

receiving a second file;

determining if a conflict exists between the first file and the second file;

if a conflict does not exist, reconciling the first file and the second file; and

if a conflict does exist, creating a conflict object identifying the first file and the second file and specifying at least one method to resolve the conflict.

2. The method of claim 1, further comprising receiving conflict resolution input from a user at a time selected by the user.

3. The method of claim 1, wherein the first file is received from an external device.

4. The method of claim 1, the second file is received from an external device.

5. The method of claim 1, wherein the first file is received via a network.

6. The method of claim 1, wherein the second file is received from local storage.

7. The method of claim 1, wherein determining if a conflict exists between the first file and the second file comprises determining whether both the first file and the second file have been altered since a most recent sync operation.

8. The method of claim 1, wherein reconciling the first file and the second file comprises one of the group consisting of replacing the first file with the second file, replacing the second file with the first file, and creating a third file based on the first file and the second file.

9. The method of claim 1, further comprising resolving at least one conflict in accordance with a conflict policy.

10. A method for performing conflict resolution, the method comprising:

receiving a selection from a user indicating that conflict resolution is to begin;

displaying first file information describing a first file;

displaying second file information describing a second file; and

displaying at least one conflict resolution option, each conflict resolution option identifying a possible method of resolving the conflict.

11. The method of claim 10, further comprising displaying a list of one or more conflicts.

12. The method of claim 11, further comprising receiving a user selection of one conflict to resolve, selected from the list of conflicts.

13. The method of claim 10, further comprising receiving a user selection of one conflict resolution option.

14. The method of claim 13, further comprising resolving the conflict in accordance with the user-selected conflict resolution option.

15. The method of claim 10, wherein the first file information and the second file information are selected based on differences between the first file and the second file.

16. The method of claim 10, wherein each conflict resolution option is specified in a resolver, the resolver being implemented in accordance with a resolver application program interface.

17. A system for performing a sync operation, comprising:

a sync manager configured to compare a first file and a second file, determine whether a conflict exists between the first file and the second file, reconcile the first file and the second file if a conflict does not exist, and create a conflict object if a conflict does exist;

a conflict store configured to hold conflict objects; and

a resolver specifying at least one method to resolve a conflict.

18. The system of claim 17, wherein the sync manager is configured to compare n files, n being an integer greater than or equal to 2;

determine whether a conflict exists between the n files, reconcile the n files if a conflict does not exist, and create a conflict object if a conflict does exist.

19. The system of claim 17, wherein the resolver is implemented in accordance with an extensible resolver application program interface.

20. The system of claim 17, further comprising a conflict manager user interface configured to display conflict information received from a conflict object.
