«Dropbox»

Let me say right up front, I'm not being paid by Dropbox for this review and I am doing this on my own accord. You can sign up for it with my Dropbox referral link.

Dropbox allows you to sync files across multiple computers and share files with other Dropbox users, or even the public (at your discretion). You can install Dropbox on your own personal computers (Windows, Mac, and even Linux), and any file you put into the "My Dropbox" folder will sync across all your computers, along with being uploaded to the Dropbox servers. There appears to be no limit to how many computers you can sync across.

Dropbox provides an off-site backup of your files. In the event of a fire or harddrive crash, your files are still secure on the Dropbox servers. In addition, you can login to the Dropbox website from any computer (at work, for example) and download any of your files you may need. It also saves previous versions of your files for 30 days (forever, with the paid version), so if you make a change or delete something that you later regret, you can restore an old version. The files are transferred using a secure connection; even the Dropbox employees can't access your personal files. And don't worry, there is a way to truly delete a file if you really want it gone forever...

If you have an iPhone, there's a free Dropbox app that allows you to access and read files in your Dropbox account. You can also take pictures with your phone and upload them to Dropbox with the app. Currently, any file you view with the iPhone is read-only. However you can delete files from within the app, and they are still adding features.

The free account gives you 2 GB (up to 5GB, see below) of online storage. There is also the option to pay for additional space: $9.99 per month/$99.00 per year for 50 GB; or $19.99 per month/$199.00 per year for 100 GB.

There is a built-in Public folder. Anything you put into this folder gets assigned a web address and you can give this link to others (they don't even have to be Dropbox users!) so they can download the file. There's also the option to share any folder with another Dropbox user. This is an excellent way to collaborate on a project. Anything that either of you put in that shared folder is automatically sent to the other person's Dropbox folder. You can share the folder with more than one person if you're working on a group project.

If you sign up using my referral link, you'll get a free extra 256 MB of online storage. Here comes my personal gain part: so will I... For the first 12 to sign up anyway; you can get a maximum extra of 3 GB, making a total of 5 GB possible with a free account. So we both win.

I travel weekly between houses, so Dropbox has been insanely useful to me to keep files in sync between my computers. And I've set up a shared folder between my dad and I. It seems reliable, I haven't had any issues with it.
