ELI5: Explain Like I'm 5

Remote backup service

A remote backup service is like having an extra copy of your stuff in a different place. Just like when you copy your homework onto a USB flash drive to keep at home and one to keep at school, a remote backup service keeps another copy of your stuff in a safe place away from your home or office. That way if something bad happens to your home or office, like a fire or flood, you still have your stuff safely tucked away.
