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.
