Abstract

Methods and systems for n-way cloning and synchronization of a user desktop image are provided. Example embodiments provide a Cloning and Synchronization System (“CSS”) which binds a server stored CVD object representing the user'"'"'s desktop image to one or more endpoint devices. Each endpoint device receives a clone of the CVD object that comprises one or more layers of the server CVD depending upon the suitability of the endpoint device hardware and operating system to the server stored desktop. The cloned CVDs in the endpoint devices are then kept synchronized by synchronization operations. In one embodiment, the CSS allows only one endpoint device to act as a master device and push up changes to the server CVD. These changes are then pushed down to the other devices using different synchronization methods dependent upon the layer.

Claims

1. A computer-implemented method in a server computing system for synchronizing a user desktop image across multiple computing devices connected via a network, comprising:

creating and storing an N-to-1 mapping in which multiple distinct computing devices are bound in a group to a single centralized virtual desktop (CVD) data object stored and maintained by the server, wherein the CVD data object defines one or more layers including user files, user profile and settings, application software, an operating system, and hardware dependent software;

cloning one or more of the layers of the CVD data object to each of the multiple computing devices;

maintaining synchronization of the at least portions of the user desktop image between all of the multiple computing devices in the group by receiving updates to one or more of the layers of the CVD data object from a one of the computing devices that has been designated a master and pushing the received updates to the one or more of the layers of the CVD object to cloned copies of the CVD data object on the remaining computing devices in the group.

2. The method of claim 1 wherein the remaining computing devices in the group are designated inactive devices and are not permitted to update the one or more of the layers of the CVD data object stored on the server.

3. The method of claim 1 wherein the cloning one or more of the layers of the CVD data object to each of the multiple computing devices further comprises:

for at least one device of the multiple computing devices,

copying a base image that includes an operating system and infrastructure software;

causing a portion of a library of drivers to be copied to the at least one device based upon a device type of the at least one device; and

copying and/or integrating user content that includes at least one of user data, user profiles, and/or user installed applications.

4. The method of claim 3 wherein the base image is not an exact replica of the base image layer of the CVD data object stored on the server.

5. The method of claim 4 wherein the base image is targeted for hardware of the at least one device.

6. The method of claim 1 wherein the cloning one or more of the layers of the CVD data object to each of the multiple computing devices does not overwrite the machine identifier settings of each of the multiple computing devices.

7. The method of claim 1 wherein the cloning one or more of the layers of the CVD data object to each of the multiple computing devices further comprises:

for at least one device of the multiple computing devices,

copying applications to the at least one device; and

copying user content that includes at least one of user data, user profiles, and/or user installed applications;

wherein the copying does not overwrite a base image that includes an operating system and infrastructure software that has already been instantiated on the at least one device.

8. The method of claim 7 wherein the base image that has already been instantiated includes a lean operating system and infrastructure software that is targeted to the at least one device.

9. The method of claim 7 wherein the copying applications to the at least one devices merges the copied applications with applications already residing on the at least one device.

10. The method of claim 1 wherein the cloning one or more of the layers of the CVD data object to each of the multiple computing devices further comprises:

for at least one device of the multiple computing devices,

copying user content that includes at least one of user data, user profiles, and/or user installed applications;

wherein the copying does not overwrite applications and a base image that includes an operating system and infrastructure software that have already been instantiated on the at least one device.

11. The method of claim 1 wherein the maintaining synchronization of the user desktop image between all of the multiple computing devices in the group further comprises:

pushing only received updates to a user content layer of the CVD object to a cloned copy of the CVD data object on at least one computing device in the group that is not designated as the master.

12. The method of claim 11 further comprising:

receiving updates to a plurality of layers of the CVD data object from a one of the computing devices that has been designated a master, wherein only one of the plurality of layers is a user content layer.

13. The method of claim 1 wherein the maintaining synchronization of the user desktop image between all of the multiple computing devices in the group further comprises:

pushing only received updates to a user content layer and a server supplied application layer of the CVD object to a cloned copy of the CVD data object on at least one computing device in the group that is not designated as the master.

14. The method of claim 1, further comprising:

receiving updates to a user content layer of the CVD data object from the computing devices in the group that are not designated the master concurrently with receiving updates to the user content layer of the CVD data object from the computing device that has been designated as the master.

15. The method of claim 1 wherein the pushing the received updates to the one or more of the layers of the CVD object to cloned copies of the CVD data object on the remaining computing devices in the group further comprises:

performing a live synchronization of user files on the remaining computing devices in the group.

16. The method of claim 15 wherein the live synchronization is performed by merging user files from the user content layer of the CVD data object with user files on the cloned copies of the CVD data object on the remaining computing devices in the group.

17. The method of claim 16 wherein the merging user files is accomplished by preserving files with the same name and location designation but with different content as separate files on the cloned copy of the CVD data object on at least one of the remaining computing devices in the group.

18. The method of claim 1 wherein the pushing the received updates to the one or more of the layers of the CVD object to cloned copies of the CVD data object on the remaining computing devices in the group further comprises:
