If you are looking for a backup solution and you have a second computer or a network drive, look into Windows File History. It is simply amazing!
As it will detect your network drive (or shared folder/drive from a computer), or external storage which you connect via USB, Windows will execute a backup of your personal files. It can do a backup once a day, down to every 10min. The way it works, is that it stores only the bits that has changed form the original file, so that you can you go back in time on them, but also keep the last version as a copy of the file, so that you can access the file for recovery purposes on any systems. If you re-install Windows, or change device (say a new Surface Pro 3, as the old one broke), all you have to do is turn back on File History, and Windows will detect everything and resume the baclup process form where it left off. You can also recover all your files from the backup drive, to get your stuff back. You just browse to the location get your files and transfer them back to your system, as the last version is stored there.
And of course, you have OneDrive, but you can't go back in time on all files, only on office documents, via the web, but it syncs with all your system.
For a limited time, in the case you didn't hear the news, if you have not yet use the Camera Roll feature, Microsoft gives you 15GB more to your current 15GB of free storage, for a total of 30GB. If you are using the camera roll feature, then you are automatically upgraded.
