Common copy compression

摘要

Embodiments of the present invention provide systems, methods, and computer storage media directed to hosting a plurality of copies of a digital content. A common component and one or more individual components from one or more copies of the digital content are generated. As such, the common component and the one or more individual components are stored, such that each individual component in conjunction with the common component represents a separate copy of the digital content. In some implementations, a compression ratio may be customized for determining the sizing of the common component and individual component.

主权项

1. One or more non-transitory computer storage media storing computer-useable instructions that, when used by one or more computing devices, cause the one or more computing devices to perform operations for hosting a plurality of unique but substantially similar copies of a digital content, the operations comprising:
extracting from the plurality of unique but substantially similar copies of the digital content a common component containing a common portion of the digital content and a plurality of individual components, each individual component containing a unique portion of the digital content and corresponding to one of the plurality of unique but substantially similar copies of the digital content; and storing, independently, the common component and each of the plurality of individual components in replacement of a stored plurality of unique but substantially similar copies of the digital content, so as to free up storage space.
