Database backup from Sql script using cursor in sql server 2008/2010

This is simple example of taking database backup from the T-sql script. In my example i have illustrated the simplest way to take the back up from the database. I have used the cursor for the same. Following is the code of the Backup script.

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

SET @path = 'C:\Backup\' 

SELECT @fileDate = CONVERT(VARCHAR(20),GETDATE(),112)

DECLARE db_cursor CURSOR FOR 
SELECT name 
FROM master.dbo.sysdatabases 
WHERE name NOT IN ('master','model','msdb','tempdb') 

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


Use the code and give me your feedback.
