摘要：
Database backup performance may be improved by copying only used portions of a database file. When the database file includes allocated but un-used pages, the unused pages are not replicated during a database backup. By replicating only the allocated and used pages in the database, the backup time may be decreased and the amount of storage required in the second file may be decreased.
