I want to take backup of my server database into my local system.so i have used the following sql query

DECLARE @name VARCHAR(50) -- database name
DECLARE @path VARCHAR(256) -- path for backup files
DECLARE @fileName VARCHAR(256) -- filename for backup
DECLARE @fileDate VARCHAR(20) -- used for file name
 

-- specify database backup directory
SET @path = 'C:\Backup\'
 

-- specify filename format
SELECT @fileDate = CONVERT(VARCHAR(20),GETDATE(),112)
 

DECLARE db_cursor CURSOR FOR
SELECT name
FROM master.dbo.sysdatabases
WHERE name IN ('Sutra') -- exclude these databases
 

OPEN db_cursor
FETCH NEXT FROM db_cursor INTO @name
 

WHILE @@FETCH_STATUS = 0
BEGIN
SET @fileName = @path + @name + '_' + @fileDate + '.BAK'
BACKUP DATABASE @name TO DISK = @fileName
 

FETCH NEXT FROM db_cursor INTO @name
END
 

CLOSE db_cursor
DEALLOCATE db_cursor

i have created the Backup folder in C: drive.but it returns the following error

Msg 3201, Level 16, State 1, Line 28
Cannot open backup device 'C:\Backup\Sutra_20121116.BAK'. Operating system error 3(The system cannot find the path specified.).
