BackupDevices Collection

后续版本的 Microsoft SQL Server 将删除该功能。 请避免在新的开发工作中使用该功能，并着手修改当前还在使用该功能的应用程序。

The BackupDevices collection contains BackupDevice objects that expose the backup devices defined on a server running Microsoft SQL Server.

注释

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 for its functioning.

With the BackupDevices collection, you can:

• Create a new backup device definition for a server running SQL Server.

• Remove a backup device definition.

For more information about creating backup devices, see BackupDevice Object.

To remove a backup device

• Use the Remove method of the BackupDevices collection of a connected SQLServer object. Indicate the targeted backup device using the backup device name or the ordinal location in the collection, as in:

  oSQLServer.BackupDevices.Remove("Northwind_Tape")
