Well, if you are going to reinstall FreeBSD - from a CD and FTP? - 
then all you really need to back up are the working files you want
to recover.   If all you want are logs, most of those are in /var/log
unless you have told it to put things elsewhere or have created 
some special logging utility.   

So, you might get by with just dumping /var.    

But, since you have the bulk of your space in /usr, I think maybe
you are putting some useful stuff in there.   So, you figure out
where your valuable stuff is and back up those filesystems.
