My question is very simple I am new to libgdx development, which is the best approach implementing a background that is to make the background move in y direction 

1)My First approach is drawing the background image 10 times towards positive y direction using camera.translate(x,y) function to move camera from bottom to top 
2)second approach is to make the camera still while making the background scroll ie drawing the background frame by frame updating the position each time

Can you please suggest which is the best approach?
