DefinitionForward recovery (フォワードリカバリ) is the recovery method that brings the database forward to its state just before the failure by means of rollforward, and it is also called forward restoration (前進復帰).
ExplanationIts starting point is data from an earlier moment, such as a backup, and it moves forward through time using the after-update values in the log. The operation is the same as a rollforward; this name simply reflects the forward direction.
