  First of all, let’s know what is backup in football betting?.

Backup is second option you stake in a coupon,when it remain only one game to play.
Example, you played 10 game in a coupon. At the end of the day, 9 games go in your favour, remaining one game. As one is yet to play,in this situation you have opportunity to backup the remaining game in the ticket. In case, the 10th game may go against your prediction.

  Now,how do you back it up?

You can backup the last game. Let’s assume you predicted home to win. You have to play another ticket opposite of what you predicted in the first ticket. So, the second ticket(the back up) you will predict Away team to win or draw.
