MediaFire is a fast and easy way to backup all of your media. It's also been recently updated to include the new "Power Upload" feature - now you can upload all your photos and videos even faster than before. You can toggle the Power Upload feature on or off at you leisure.
This update also optimizes MediaFire for the iPhone 6 and 6 Plus, and includes various bug fixes.
You can download MediaFire for free on the App Store.
