Tapes Property

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 Tapes property specifies one or more tape devices used as a database backup target or restore source.

语法

object
.Tapes [=value]

Parts

  • object
    An expression that evaluates to an object in the Applies To list

  • value
    A SQL Distributed Management Objects (SQL-DMO) multistring that names one or more tape devices

Data Type

String

Modifiable

Read/write

Prototype (C/C++)

HRESULT GetTapes(SQLDMO_LPBSTR pRetVal);
HRESULT SetTapes(SQLDMO_LPCSTR NewValue);
注意注意

SQL-DMO strings are always returned as OLE BSTR objects. A C/C++ application obtains a reference to the string. The applications must release the reference using SysFreeString.

注释

The backup medium for a backup or restore operation is specified using the Devices, Files, Pipes, or Tapes properties. Only one medium type can be specified for any backup or restore operation, but multiple media can be specified.

Set the Tapes property to specify one or more tape devices as the backup medium. Specify more than a single tape device to stripe the backup operation or to restore from a striped backup set.

For more information about setting multistring parameters, see Using SQL-DMO Multistrings.
