If you’ve never heard of or used Dropbox, you owe it to yourself to give it a shot. And if you’re not backing up your important files on a regular basis, you’re really begging for trouble.

Everyone is in need of a good backup, and Dropbox fits the bill very well for most users. In addition, it provides excellent syncing functionality to keep your data up to date between all of the computers that you use. It’s free for the first 2 GB, and above that you can pay for either 50 or 100 GB of space. We’ll be addressing Dropbox Pro accounts (50 or 100 GB accounts) in this article.

In my experience, Dropbox is the most easy to use, mature, and trustworthy service available for online backup and syncing. It does have one caveat, however: the most space you can use is 100 GB (at least for the moment). You can’t even pay for more in a single account. Granted, 100 GB is a lot of space (especially to back up online), but if you’re like me, you have more than 100 GB of precious home movies of your little ones.

So what do you do? Find out after the break…
