Abstract
A high tier storage area stores a stub file and a lower tier cloud storage area stores the file corresponding to the stub file. When a client apparatus requests segments of the file from the high tier storage area, reference is made to the stub file to determine a predicted non-sequential pattern of requests to the segments by the client apparatus. The high tier storage area follows the predicted non-sequential pattern of requests to retrieve the segments of the file from the cloud prior to the client apparatus actually requesting the segments. As such, the file may be efficiently provided to the client apparatus while also efficiently storing the file on the lower tier cloud storage area.
