Patent Issued for Distributed Backup and Versioning

July 15, 2014

By a News Reporter-Staff News Editor at Journal of Technology -- Microsoft Corporation (Redmond, WA) has been issued patent number 8769055, according to news reporting originating out of Alexandria, Virginia, by VerticalNews editors.

The patent's inventors are Murphy, Elissa E. S. (Seattle, WA); Virk, Navjot (Bellevue, WA).

This patent was filed on April 24, 2009 and was published online on July 1, 2014.

From the background information supplied by the inventors, news correspondents obtained the following quote: "As computing devices become more prevalent and widely used among the general population, the amount of data generated and utilized by such devices has rapidly increased. For example, recent advancements in computing and data storage technology have enabled even the most limited form-factor devices to store and process large amounts of information for a variety of data-hungry applications such as document editing, media processing, and the like. Further, recent advancements in communication technology can enable computing devices to communicate data at a high rate of speed. These advancements have led to, among other technologies, the implementation of distributed computing services that can, for example, be conducted using computing devices at multiple locations on a network. In addition, such advancements have enabled the implementation of services such as network-based backup, which allow a user of a computing device to maintain one or more backup copies of data associated with the computing device at a remote location on a network.

"Existing system and/or data backup solutions enable a user to store backup information in a location and/or media separate from its original source. Thus, for example, data from a computing device can be backed up from a hard drive to external media such as a tape drive, an external hard drive, or the like. However, in an implementation of network-based backup and/or other solutions that can be utilized to provide physically remote locations for storing backup data, costs and complexity associated with transmission and restoration of user data between a user machine and a remote storage location can substantially limit the usefulness of a backup system. For example, in the case where backup data is stored at a remote network location, data associated with respective versions of an original copy of a file and/or system image can be transmitted to remote storage, where the respective versions can later be retrieved for restoration. However, a sizeable amount of data is generally transmitted over the network in such an example, thereby consuming expensive bandwidth. In view of the foregoing, it would be desirable to implement network-based backup techniques with improved efficiency."

Supplementing the background information on this patent, VerticalNews reporters also obtained the inventors' summary information for this patent: "The following presents a simplified summary of the innovation in order to provide a basic understanding of some aspects described herein. This summary is not an extensive overview of the claimed subject matter. It is intended to neither identify key or critical elements of the claimed subject matter nor delineate the scope of the subject innovation. Its sole purpose is to present some concepts of the claimed subject matter in a simplified form as a prelude to the more detailed description that is presented later.

"The subject innovation relates to systems and/or methodologies that facilitate distributed backup and versioning techniques for network-based backup architectures. When data is committed to a backup system, a backup version can be created. The generated backup version can be a complete rendition of data or the generated backup version can be a differential between the data and backup information previously committed to the system. The generated backup version can be replicated across a distributed network of peers (e.g., user devices). Replication can be based upon a desired level of redundancy of versions, location of peers, network topology of peers, storage capacity of peers, health of peers, type of peer, and the like. In addition, versions can be retained based upon a configurable number of desired versions.

"In accordance with one aspect, a hybrid backup architecture can be employed wherein backup data and/or versions of backup data can be retained on a global location within a network or internetwork (e.g., a 'cloud') as well as one or more peers. Accordingly, some or all versions can be obtained from either the cloud or a nearby peer, thus reducing latency and bandwidth consumption associated with restore operations. In one example, selection of locations to be utilized for storing and/or retrieving backup information (e.g., backup versions) can be selected in an intelligent and automated manner based on factors such as, but not limited to, availability of locations, network topology, location resources, or so on.

"The following description and the annexed drawings set forth in detail certain illustrative aspects of the claimed subject matter. These aspects are indicative, however, of but a few of the various ways in which the principles of the innovation may be employed and the claimed subject matter is intended to include all such aspects and their equivalents. Other advantages and novel features of the claimed subject matter will become apparent from the following detailed description of the innovation when considered in conjunction with the drawings."
