I’ve only gotten 3 referrals up until now, but with other stuff was already at 4.5 GB free. You get 250 MB free by signing up under a referral link, and I get 250 GB extra too. Check out this Lifehacker guide that details all the possibilities. It may not be big enough for a full backup, but plenty for my important files. The Dropbox free version offers up 2 GB of storage free to start, which you can increase to nearly 20 GB with various tasks. Other online storage apps like Box.net or SkyDrive don’t work nearly as seamlessly for me.

The best part is that usually I forget it’s even there. I like that it’s a real folder on my computer that is also invisibly synchronized and backed up in the cloud.
