Last summer I replaced the 160GB HDD in my MacBook with a 500GB drive. In the process I put the old drive in a new external enclosure and planned to use it to backup my home folder. Until now, that never really happened, but a few weeks ago when I did a fresh install of Snow Leopard I decided it would be a good time to finally get my backups going.
I already had a pretty good idea that I wanted to go with Carbon Copy Cloner or Super Duper!. I had already had some experience with CCC from my job last summer, but I had read an article on Daring Fireball about backup and he used Super Duper!. I decided to checkout Super Duper! first since I hadn’t really looked into it much before.
It turns out that you can download Super Duper! for free, but there is also a paid version that unlocks some more features. For the most basic backups either program works great.
