of the database. Recovery types are designed to Manage transaction log routine maintenance. A recovery model can be a database property that controls how transactions are logged, if the transaction log involves (and permits) backing up, and what varieties of restore operations are available.

Recovery reapplies the alterations created by numerous concurrent procedures, and as a consequence occasion or media recovery will take for a longer period than the time it took external hard drive repair to originally create the improvements to the database.
