Point-in-time recovery
Point-in-time recovery in the context of computers is a system whereby a set of data or a particular setting can be restored or recovered from a time in the past. An example of this is Windows XP's feature of being able to restore operating system settings from a past date (before data corruption occurred, for example), or PostgreSQL's feature of being able to view a database table and its data as it was at a particular date in the past. Also, Time Machine (Apple software) for Mac OS X is an example of Point-in-time recovery.
