Run the following 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
DECLARE @fileHour VARCHAR(2) -- used for file name
DECLARE @fileMinutes VARCHAR(2) -- used for file name
-- specify database backup directory
SET @path = 'C:\Backup\'
SELECT @fileDate = CONVERT(VARCHAR(20),GETDATE(),112)
SELECT @fileHour = CONVERT(VARCHAR(2 ),DATEPART(hh, GETDATE()) )
SELECT @fileMinutes = CONVERT(VARCHAR(2 ),DATEPART(MINUTE, GETDATE()) )
DECLARE db_cursor CURSOR FOR
SELECT name
FROM master.dbo.sysdatabases
WHERE name NOT IN ('master','model','msdb','tempdb') --exclude the databases that you don't want to backup
OPEN db_cursor
FETCH NEXT FROM db_cursor INTO @name
WHILE @@FETCH_STATUS = 0
BEGIN
SET @fileName = @path + 'Diff_' + @name + '_' + @fileDate + '_' + @fileHour + '_' + @fileMinutes+ '.BAK'
BACKUP DATABASE @name TO DISK = @fileName WITH DIFFERENTIAL
FETCH NEXT FROM db_cursor INTO @name
END
CLOSE db_cursor
DEALLOCATE db_cursor
