Friends Don't Let Friends Lose Data
A couple of months ago, I started using a free backup service called Mozy. It automatically makes an offsite backup of my files each night. You get 1 GB of storage for free, 2 GB if you are willing to let them send you the occasional email (they haven't sent me any emails yet).
No one ever wants to lose their files, and everyone knows someone whose life ground to a halt because of a laptop crash. Mozy lets you stop worrying without having to pay anything.
Now why am I shilling for them? Well, I do love the service. Heck, I even wrote about them without any inducements. And now they've added a referral program so that for every 4 people you get to sign up, you get another 1 GB of free storage.
So if you don't already have an offsite backup solution, I strongly urge you to check out Mozy and to sign up with my referral code to thank me for pointing out this cool solution.
