Abstract
A two-level storage system selectively enables early discard of data from an upper level either immediately or at the end of a predetermined sequence of operation. A copy of data in such upper level is discarded immediately while altered copies of data are discarded at the end of the predetermined sequence of operations. Error conditions inhibit discarding altered data.
