If you'd rather have manual control over which files and documents you back up and how you organize them on the cloud, then you might want to consider using Google Drive or third-party services like Dropbox. You can download and use these applications on your Android phone to upload pretty much any file, including media, manually to a preferred location on the cloud and organize them. You can create additional folders to move around your files and even view them anytime via mobile or desktop. The process for that is as simple as selecting the files you want to back up and uploading them to the cloud.
