Osservazioni
Microsoft SQL Server provides the Simple, Bulk-Logged, and Full Recovery models to simplify recovery planning, to simplify backup and recovery procedures, and to clarify tradeoffs between system operational requirements. An application can use the RecoveryModel property to specify which recovery model to use.
[!NOTA]
If an application calls RecoveryModelon an instance of SQL Server version 7.0, the constant, SQLDMO_E_SQL80ONLY, and the message "This property or method requires Microsoft SQL Server 2000 or later" are returned.
