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 READ_ONLY FOR 

SELECT name

FROM master.dbo.sysdatabases

WHERE name NOT IN ('master','model','msdb','tempdb')  -- exclude these databases

OPEN db_cursor
