Cette fonctionnalité sera supprimée dans une prochaine version de Microsoft SQL Server. Évitez d'utiliser cette fonctionnalité dans de nouveaux travaux de développement et prévoyez de modifier les applications qui utilisent actuellement cette fonctionnalité.

The BackupDevice object represents the properties of a Microsoft SQL Server backup device.

Notes

SQL Server backup devices specify the behavior of specific backup media, usually tape. Backup devices are not required when issuing a BACKUP or RESTORE statement and are not required by the Backup object.

With the BackupDevice object, you can:

• Define a new backup device for a server running SQL Server.

• Change the definition of an existing SQL Server backup device.

The Name property of the BackupDevice object must match the definition of the sysname SQL Server data type.

To create a backup device

1. Create a BackupDevice object.

2. Set the Name property.

3. Set properties that define the behavior or use of the device, such as the tape label skip parameter or the physical location.

4. Add the BackupDevice object to the BackupDevices collection of a connected SQLServer object.
