大家帮我找找错误啊！！
谢谢！！！

英文版联机丛书上是这样写的

A. Back up the entire MyNwind database

Note The MyNwind database is shown for illustration only.

This example creates a logical backup device in which a full backup of the MyNwind database is placed.

-- Create a logical backup device for the full MyNwind backup.
USE master
EXEC sp_addumpdevice 'disk', 'MyNwind_1', 
   DISK ='c:\Program Files\Microsoft SQL Server\MSSQL\BACKUP\MyNwind_1.dat'

-- Back up the full MyNwind database.
BACKUP DATABASE MyNwind TO MyNwind_1

B. Back up the database and log

This example creates both a full database and log backup. The database is backed up to a logical backup device called MyNwind_2, and then the log is backed up to a logical backup device called MyNwindLog1.

Note Creating a logical backup device needs to be done only once.

-- Create the backup device for the full MyNwind backup.
USE master
EXEC sp_addumpdevice 'disk', 'MyNwind_2',
   'c:\Program Files\Microsoft SQL Server\MSSQL\BACKUP\MyNwind_2.dat'

--Create the log backup device.
USE master
EXEC sp_addumpdevice 'disk', 'MyNwindLog1',
   'c:\Program Files\Microsoft SQL Server\MSSQL\BACKUP\MyNwindLog1.dat'

-- Back up the full MyNwind database.
BACKUP DATABASE MyNwind TO MyNwind_2

-- Update activity has occurred since the full database backup.

-- Back up the log of the MyNwind database.
BACKUP LOG MyNwind 
   TO MyNwindLog1
