I can relate to this post as until recently I also just too lazy to do regular data backup. It seems there are a host of new companies trying to make it easier and fighting what must just be human nature that leads everyone to believe their data will not be lost.
This post refers to a new startup called Backblaze, and I have friends that use Mozy, but for me the solution was buying the Apple Time Capsule and syncing several computers to it. In my case I had the unfortunate experience of having a hard drive fail on my laptop I had not backed up in about six months. Why? Well because I just was being lazy. With the Time Capsule and the new host of backup services it can be auto-magic. I really do sleep better now 
With all the digital music, photos, and other things you might want to take with you do yourself a favor and get a data backup service or something that just does it for you.
