Title: Reducing storage costs associated with backing up a database

Abstract: Techniques are disclosed for backing up and/or restoring data. In one embodiment, a request is received to back up at least a first unit of data stored in a database. Upon determining that the first unit of data is at least partially derived from a second unit of data stored in the database, a backup may be generated that includes less than all of the first unit of data. Subsequently, the first unit of data may be fully restored from the backup.
