Method and system for synchronizing data shared among peer computing devices

摘要: Disclosed is a data synchronization service for use in peer-to-peer computing environment. Selected objects are copied onto selected devices. A running on each device monitors changes. When change detected, the sends notification to other devices so that they can update their copies of object. user access object from any device, knowing he will retrieve latest version Instead incurring costs storing large file every “ghosts” some ghosting stores only metadata about rather than entire file.
