| SQL-DMO strings are always returned as OLE BSTR objects. A C/C++ application obtains a reference to the string. The application must release the reference using SysFreeString. |
解説
The backup medium for a backup or restore operation is specified using either the Devices, Files, Pipes, or Tapes properties. Only one medium type can be specified for any backup or restore operation, but multiple media (of the same type) may be specified.
Set the Devices property to specify one or more Microsoft SQL Server backup devices as the backup medium. Specify more than a single database file to stripe the backup operation or restore from a striped backup set.
