You need to investigate your VLFs. How many do you have? Of those you have, how many are in use (status = 2)? And, of those which are in use, where are they?
Don't worry too much of the "LOGBACKUP" status, you will have that as soon as you aren't in simple recovery model and you also have more than one used VLF (which is pretty normal). Some more info in here: http://karaszi.com/large-transaction-log-file
