Abstract
In one aspect of metadata track entry sorting in accordance with the present description, recovery logic sorts a list of metadata entries as a function of a source data track identification of each metadata entry to provide a second, sorted list of metadata entries, and generates a recovery volume which includes data tracks which are a function of one or more data target tracks identified by the sorted list of metadata entries. Because the metadata entry contents of the sorted list have been sorted as a function of source track identification number, the particular time version of a particular source track may be identified more quickly and more efficiently. As a result, recovery from data loss may be achieved more quickly and more efficiently thereby providing a significant improvement in computer technology. Other features and aspects may be realized, depending upon the particular application.
