You may as well put your home drive on the SSD and tar it up every night onto a spinning drive. As a matter of fact, tar the whole system.
tar -cvpzf backup.tar.gz —exclude=/backup.tar.gz —one-file-system /

Actually I rsync to an external USB HDD (Passport) as a backup. ;-)

There are 2 problems with that (IMO). First, the data on /home tends to change a lot more often. One of the big problems with SSD tech is that you only get so many writes to a given sector. Granted, with today's stuff, that's not as much of a worry as it once was, but depending upon how you use stuff, it very well could be. Second, per GB of space an SSD is much more expensive than a traditional disk. I can buy 4TB of space for /home on a spinning disk for the same price I can get 500GB of SSD.
