Finding an awesome free automatic online backup site is a lot like getting tickets to a sold-out concert. Sure, they’re out there, but only if you’re willing to give up an arm, a leg, and a firstborn.

It is unfortunate because free automatic online backup is great. It is great for those frequently on the go, those too cheap to buy another hard drive, or those tin-foil-hat folk who plan data backup to the extreme. But trying to find a site that’s inexpensive or free as well as unobtrusive is damn near impossible. Until now.

The extraordinary cheap Mozy (5$/month) is the best site I’ve come across and I doubt better exists. For starters, you can give the automatic online backup site a whirl absolutely free. Just download the little application and it will politely sit in the corner of your taskbar and backup whenever you want – you get up to two gigabytes of free online space. And those are incremental backups too: you can restore a file from yesterday, or the same file from a week ago.

Toss a mere $5 to Mozy on a monthly basis and that 2GB of space expands to infinity. It is the cheapest deal I have seen on the net, and for all the features – web access to files, scheduled backups, and encryption – it’s worth every penny.
