Abstract

A system and method for migrating a directory across a network. In one embodiment a computer network implements a method comprising accessing a stored directory in a first domain of a computer network, copying the directory to a second domain of said computer network, creating an indication that the directory has been copied to the second domain and accessing the directory on the second domain. The method may be triggered by a user locally logging on to the second domain. The method may also occur in response to a request for directory migration provided by a user. In further embodiments, the directory may migrate to additional domains, and may ultimately migrate back to the first domain.

Claims

1. A method comprising:

accessing a stored directory in a first domain of a computer network;

copying the directory to a second domain of said computer network;

creating an indication that the directory has been copied to the second domain;

accessing the directory on the second domain.

2. The method of claim 1 wherein the copying occurs in response to a user accessing the second domain.

3. The method of claim 2 wherein the user accesses the second node by locally logging in to the second domain.

4. The method of claim 1 wherein copying the directory and creating the indication occurs in response to a directory migration request provided by a user.

5. The method of claim 1 wherein copying the directory and creating the indication occurs in response to an indication that the user is in proximity to the second domain.

6. The method of claim 5 wherein the indication that the user is in proximity to the second domain comprises the network detecting the user'"'"'s proximity to the second domain via a wireless locator system, such as GPS.

7. The method of claim 1 wherein copying the directory and creating the indication occurs in response to an indication that the user will be in proximity to the second domain.

8. The method of claim 7 wherein the indication that the user will be in proximity to the second domain comprises the network determining that the user will be in proximity to the second domain from a schedule indicative of the user'"'"'s movements.

9. The method of claim 1 wherein the method further comprises:

copying the directory from the second domain to the first domain;

deleting the indication that the directory has been copied to the second domain;

deleting the copy of the directory from the second domain;

accessing the directory on the first domain.

10. The method of claim 1 wherein the method further comprises:

copying the directory from the second domain to a third domain;

modifying the indication that the directory has been copied to the second domain to indicate that the directory has been copied to the third domain;

deleting the copy of the directory from the second domain;

accessing the directory on the third domain.

11. The method of claim 1 wherein the network is a wide area network.

12. The method of claim 1 wherein the directory is a home directory.

13. The method of claim 1 wherein the indication that the directory has been copied to the second domain is stored on the first domain.

14. The method of claim 13 wherein the indication that the directory has been copied to the second domain is stored in the directory being copied.

15. The method of claim 1 wherein the indication that the directory has been copied contains the network address of the second domain and the location of the copied directory on that domain.

16. The method of claim 1 wherein the copying of the directory includes compressing the directory and transferring a compressed form of the directory to the second domain.

17. The method of claim 1 wherein changes to the directory located on the first domain are prevented while accessing the directory on the second domain.

18. A computer network comprising:

a plurality of network domains, each domain further comprising one or more nodes;

a storage medium including instructions executable by one or more of the plurality of nodes to implement a method comprising;

accessing a stored directory in a first domain of said computer network;

copying the directory to a second domain of said computer network;

creating an indication that the directory has been copied to the second domain;

accessing the directory on the second domain.

19. The computer network of claim 18 wherein the user accesses the second node by locally logging in to the second domain.

20. The computer network of claim 18 wherein copying the directory and creating the indication occurs in response to a directory migration request provided by a user.

21. The computer network of claim 18 wherein copying the directory and creating the indication occurs in response to an indication that the user is in proximity to the second domain.

22. The computer network of claim 18 wherein copying the directory and creating the indication occurs in response to an indication that the user will be in proximity to the second domain.

23. The computer network of claim 18 wherein the method further comprises:

copying the directory from the second domain to the first domain;

deleting the indication that the directory has been copied to the second domain;

deleting the copy of the directory from the second domain;

accessing the directory on the first domain.

24. The computer network of claim 18 wherein the method further comprises:

copying the directory from the second domain to a third domain;

modifying the indication that the directory has been copied to the second domain to indicate that the directory has been copied to the third domain;

deleting the copy of the directory from the second domain;

accessing the directory on the third domain.

25. The computer network of claim 18 wherein the indication that the directory has been copied to the second domain is stored in the directory being copied.

26. The computer network of claim 18 wherein the indication that the directory has been copied contains the network address of the second domain and the location of the copied directory on that domain.

27. The computer network of claim 18 wherein the copying of the directory includes compressing the directory and transferring a compressed form of the directory to the second domain.

28. The computer network of claim 18 wherein changes to the directory located on the first domain are prevented while accessing the directory on the second domain.

29. A computer readable medium including program instructions executable to implement a method comprising:

accessing a stored directory in a first domain of said computer network;

copying the directory to a second domain of said computer network;

creating an indication that the directory has been copied to the second domain;

accessing the directory on the second domain.

30. The computer readable medium of claim 29 wherein the user accesses the second node by locally logging in to the second domain.

31. The computer readable medium of claim 29 wherein copying the directory and creating the indication occurs in response to a directory migration request provided by a user.

32. The computer readable medium of claim 29 wherein copying the directory and creating the indication occurs in response to an indication that the user is in proximity to the second domain.

33. The computer readable medium of claim 29 wherein copying the directory and creating the indication occurs in response to an indication that the user will be in proximity to the second domain.

34. The computer readable medium of claim 29 wherein the method further comprises:

copying the directory from the second domain to the first domain;

deleting the indication that the directory has been copied to the second domain;

deleting the copy of the directory from the second domain;

accessing the directory on the first domain.

35. The computer readable medium of claim 29 wherein the method further comprises:

copying the directory from the second domain to a third domain;
