Zusammenfassung:A full backup of a database is created at a first point in time. To restore the database to its state at a second point in time (after the full backup was created), a set of incremental backups, including the incremental backup that corresponds to the second point in time and incremental backups created between the first and second points in time, is used in reverse chronological order. For example, blocks in the full backup can be selectively overwritten with corresponding blocks from the incremental backups in reverse chronological order.
