Abstract:
A networked digital data processing system has two or more client devices, a network including a set of interconnections for transferring information between the client devices, at least one of which has a local data file storage element for locally storing and providing access to digital data files arranged in one or more client filesystems. A migration file server includes a migration storage element that stores data portions of files from the client devices, a storage level detection element that detects a storage utilization level in the storage element, and a level-responsive transfer element that selectively transfers data portions of files from the client device to the storage element.
