例如备份数据库 把MyNwind备份到 'c:\Program Files\Microsoft SQL Server\MSSQL\BACKUP\MyNwind_1.dat'并取名为
-- 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
-- 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
FROM MyNwind_1
