your stick or flash drive will have a letter by the side of it e,f,g,h,i,j,k etc so when you click back up data in the scroll down box click the letter drive that you have your stick in .....but if you back up to the internet that ok anyway...but also remember this..dont ever pull the stick out you need to click on the remove safely icon in the bottom right corner..you just pull it out..you could damage your data
