Abstract
During file backup to an off-line storage facility, attributes are included which facilitate the placement of the file into a proper pool during a subsequent restoration operation. This avoids multiple data transfers that may have otherwise been occasioned as a result of improper pool selection during the restore due to the loss or to the unavailability of necessary file attributes when the file was restored.
