Avoid the horror story of losing all of your content when your phone or device gets stolen or breaks and you have none of it backed up anywhere!

It's always better to keep your content on an external drive when possible or even two just to be sure that it is safe! I suggest uploading all of your new content files to your drive as soon as possible and naming them so they are easy to search through. You can even go through and make organized folders based on content type, category etc.
