Data recovery strategies will usually be built around the backup strategy. Any recovery situation naturally implies that some failure has occurred. The recovery action will depend on what that failure was. As such, a recovery strategy will consist of a set of failure scenarios and their resolution. The aim of this section is to categorize the main potential failures. How each failure is dealt with specifically is of course RDBMS dependent. Whatever software you choose, the recovery steps for the failure scenarios below need to be fully documented.
