备注
The Backup2 object extends the functionality of the Backup object for use with features that were introduced in SQL Server 2000. It also inherits the properties and methods of the Backup object. With the Backup2 object, you can:
- Retrieve or specify a backup or media set password from SQL Server 2000 and later.
The properties of the Backup2 object may not be compatible with instances of SQL Server version 7.0 or earlier. For information about using the Backup2 object in an application that also runs with an instance of SQL Server 7.0, refer to the Remarks section for specific properties. For more information, see Programming Extended SQL-DMO Objects.
