Using the backup interface command makes it more complex than it needs to be. You should get very satisfactory backup routing by configuring a second static route with the higher Administrative Distance (like your second option).

one of things I like to do is use equal wieght static routes. This will allow for load sharing and if one goes down the other will still be active. If you only want to use one line at a time use the ip route statement with the weight.
