20100094817 | STORAGE-NETWORK DE-DUPLICATION - Techniques are provided for de-duplication of data. In one embodiment, a system comprises de-duplication logic that is coupled to a de-duplication repository. The de-duplication logic is operable to receive, from a client device over a network, a request to store a file in the de-duplicated repository using a single storage encoding. The request includes a file identifier and a set of signatures that identify a set of chunks from the file. The de-duplication logic determines whether any chunks in the set are missing from the de-duplicated repository and requests the missing chunks from the client device. Then, for each missing chunk, the de-duplication logic stores in the de-duplicated repository that chunk and a signature representing that chunk. The de-duplication logic also stores, in the de-duplicated repository, a file entry that represents the file and that associates the set of signatures with the file identifier. | 04-15-2010 |
20130212161 | INDEPENDENT SYNCHRONIZATION OF VIRTUAL DESKTOP IMAGE LAYERS - 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. | 08-15-2013 |

20140149347 | MERGING OF DESKTOP IMAGES - 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 push up changes to the server CVD. User files are synchronized with the all endpoints using a live sync process. System and managed applications may be intelligently merged into an inactive device rather than overwriting data modified on the inactive device. | 05-29-2014 |

20150227357 | DESKTOP IMAGE MANAGEMENT FOR VIRTUAL DESKTOPS USING A BRANCH REFLECTOR - A desktop image management system is described that can efficiently distribute updates to virtual desktops running on host servers in a data center. The system is comprised of a central server and multiple agents, each agent installed on a virtual machine. When a VM receives an update from the central server, the files are stored in a single instance store on the host server. Corresponding stub files (empty of content) are created on the VM for each file in the single instance store. The stub files are marked to indicate that the stub file is mapped to the single instance store. When the guest operating system requests to read the stub file, the virtual disk layer of the host server detects that the requested block has been marked and fetches the content of the file from the single instance store. | 08-13-2015 |

The system is comprised of a central server and multiple agents, each agent installed on a virtual machine. When a VM receives an update from the central server, the files are stored in a single instance store on the host server. The agent running on the VM then creates a corresponding stub file (empty of content) on the VM for each file in the single instance store. The agent further marks the stub file to indicate that the stub file is mapped to the single instance store. When the guest operating system requests to read the stub file, the virtual disk layer of the host server detects that the requested block has been marked and fetches the content of the file from the single instance store. | 08-13-2015 |
20150227567 | DESKTOP IMAGE MANAGEMENT FOR VIRTUAL DESKTOPS USING ON-DEMAND STUB CREATION - A desktop image management system is described that can efficiently distribute updates to virtual desktops running on host servers in a data center. The system is comprised of a central server and multiple agents, each agent installed on a virtual machine. When a VM receives an update from the central server, the files are stored in a single instance store on the host server. On a first request to open the directory containing the files on the VM, corresponding stub files are created on-demand for each file in the single instance store. The stub files are marked to indicate that they are mapped to the single instance store. Subsequently, when the guest operating system requests to read the stub file, the virtual disk layer of the host server detects that the requested block has been marked and fetches the content of the file from the single instance store. | 08-13-2015 |
