I've been careless about backups in the past. It's getting more important to me to be a bit more careful. I have CCC and, of course, time machine. Currently I just have CCC doing a nightly backup to a Lacie external HDD. The Lacie is small, 1/2 the capacity of the SSD in the macbook. I've ordered a new 4tb WD external drive to use as a backup drive. I don't really ever anticipate have room issues on the internal SSD, it's a 500GB drive and I don't work with photos or videos. I'm wondering if I should partition the 4TB drive into 2 or 3 partitions - one for Time machine, one for CCC (is that even necessary - running both ?), and maybe one for archiving - even though I don't see the need for it now. I have a bootcamp partition on the SSD also with windows 7 running a few applications that are not os/x compatible. After setting up bootcamp and windows 7, I installed parallels to run windows 7 in a VM. Somehow I'd like to make sure that mess gets backed up as well.
