Backup your files to a flash drive automatically. It's secure and a life saver should your hard drive or computer ever go down.
Goto Start -> right click and choose Control Panel. In Control Panel choose File History and click Advance Settings. Here you change the frequency of backups, for most users an external drive will work great or a flash drive.
In here you might want to do a cleanup every few months, or so and even change the frequency of backup times.
