Abstract
A method and apparatus for dynamically balancing the loading of video data storage devices facilitates the transfer of video data by acquiring a listing of locations and loading of all segments of a requested video data. Those storage devices containing copies of each segment of the video data having a least loading are selected. If the loading of the storage devices exceed their maximum capacity, the segment is divided into sub-segments and stored to storage devices with minimum loading. The presence of all segments of the requested video data is determined. If there are missing segments of the requested video data, each of those missing segments is assigned a file identification and file location, such that those missing segments are retrieved from a back-up storage device and assigned to data storage devices having the least loading for transfer to a requesting computer system.
