Abstract

Claims (48)

1. A method for synchronizing metadata using a proxy synchronization server, the method comprising:

supporting communication between a master synchronization server and a client device through the proxy synchronization server via synchronization sessions between the proxy synchronization server and the master synchronization server and between the proxy synchronization server and the client device;

synchronizing the metadata during a first time, via the synchronization sessions, across the master synchronization server, the proxy synchronization server, and the client device in response to a change made to synchronized data on the client device with the metadata being associated with the change made to the synchronized data, wherein synchronizing the metadata comprises updating the metadata at the master synchronization server and the proxy synchronization server; and

synchronizing the change made to the synchronized data during a second time, via synchronization sessions, across the master synchronization server, the proxy synchronization server, and the client device in response to the change made to the synchronized data on the client device, wherein the second time is later than the first time.

2. The method of claim 1 , further comprising:

applying a conflict resolution algorithm on the proxy synchronization server when receiving conflicting changes to the metadata.

3. The method of claim 1 , wherein synchronizing the metadata during the first time occurs in real-time when a synchronization session between two or more devices is established.

4. The method of claim 1 , wherein, during the synchronizing of the metadata, the change made to the synchronized data is not synchronized on the master synchronization server, the proxy synchronization server, and the client device.

5. The method of claim 1 , further comprising:

receiving, if the change to the synchronized data comprises a new file or an updated file on the client device, a file comprising a copy of the new file or the updated file from the client device;

storing the file; and

sending the file to an interested device that communicates with the proxy synchronization server.

6. The method of claim 1 , further comprising:

backing up, on the proxy synchronization server, all synchronized data from the client device, wherein only specified synchronized data from the client device is backed up on the master synchronization server.

7. The method of claim 6 , wherein the backing up the synchronized data on by the proxy synchronization server further comprises:

backing up, on the proxy synchronization server, all versions of the specified synchronized data, wherein only a latest version of the specified synchronized data is backed up to the master synchronization server.

8. A non-transitory computer-readable medium comprising computer-executable code for synchronizing metadata using a proxy synchronization server, comprising:

code for supporting communication between a master synchronization server and a client device through the proxy synchronization server via synchronization sessions between the proxy synchronization server and the master synchronization server and between the proxy synchronization server and the client device;

code for synchronizing the metadata during a first time, via the synchronization sessions, across the master synchronization server, the proxy synchronization server, and the client device in response to a change made to synchronized data on the client device with the metadata being associated with the change made to the synchronized data, wherein synchronizing the metadata comprises updating the metadata at the master synchronization server and the proxy synchronization server; and

code for synchronizing the change made to the synchronized data during a second time, via synchronization sessions, across the master synchronization server, the proxy synchronization server, and the client device in response to the change made to the synchronized data on the client device, wherein the second time is later than the first time.

9. The non-transitory computer-readable medium of claim 8 , further comprising:

code for applying a conflict resolution algorithm on the proxy synchronization server when receiving conflicting changes to the metadata.

10. The non-transitory computer-readable medium of claim 8 , wherein synchronizing the metadata during the first time occurs in real-time when a synchronization session between two or more devices is established.

11. The non-transitory computer-readable medium of claim 8 , wherein the code for the synchronizing of the metadata further comprises:

code for not synchronizing the change made to the synchronized data on the master synchronization server, the proxy synchronization server, and the client device.

12. The non-transitory computer-readable medium of claim 8 , further comprising:

code for receiving, if the change to the synchronized data comprises a new file or an updated file on the client device, a file comprising a copy of the new file or the updated file from the client device;

code for storing the file; and

code for sending the file to an interested device that communicates with the proxy synchronization server.

13. The non-transitory computer-readable medium of claim 8 , further comprising:

code for backing up, on the proxy synchronization server, all synchronized data from the client device, wherein only specified synchronized data from the client device is backed up on the master synchronization server.

14. The non-transitory computer-readable medium of claim 13 , wherein the code for backing up the synchronized data on by the proxy synchronization server further comprises:

code for backing up, on the proxy synchronization server, all versions of the specified synchronized data, wherein only a latest version of the specified synchronized data is backed up to the master synchronization server.

15. A proxy synchronization server configured to:

support communication between a master synchronization server and a client device via synchronization sessions between the proxy synchronization server and the master synchronization server and between the proxy synchronization server and the client device;

synchronize metadata during a first time, via the synchronization sessions, across the master synchronization server, the proxy synchronization server, and the client device in response to a change made to synchronized data on the client device with the metadata being associated with the change made to the synchronized data, wherein synchronizing the metadata comprises updating the metadata at the master synchronization server and the proxy synchronization server; and

synchronize the change made to the synchronized data during a second time, via synchronization sessions, across the master synchronization server, the proxy synchronization server, and the client device in response to the change made to the synchronized data on the client device, wherein the second time is later than the first time.

16. The proxy synchronization server of claim 15 , wherein the proxy server is further configured to:

apply a conflict resolution algorithm on the proxy synchronization server when receiving conflicting changes to the metadata.

17. The proxy synchronization server of claim 15 , wherein, during the synchronizing of the metadata, the change made to the synchronized data is not synchronized on the proxy synchronization server.

18. The proxy synchronization server of claim 15 , wherein the proxy synchronization server is further configured to:

receive, if the change to the synchronized data comprises a new file or an updated file on the client device, a file comprising a copy of the new file or the updated file from the client device;

store the file; and

send the file to an interested device that communicates with the proxy synchronization server.

19. The proxy synchronization server of claim 15 , wherein the proxy synchronization server is further configured to:

back up, on the proxy synchronization server, all synchronized data from the client device, wherein only specified synchronized data from the client device is backed up on the master synchronization server.

20. The proxy synchronization server of claim 15 , wherein the proxy synchronization server is further configured to:

back up, on the proxy synchronization server, all versions of the specified synchronized data, wherein only a latest version of the specified synchronized data is backed up to the master synchronization server.
