click on the iPod Nano icon.
On that first page in the right pane, you will see the backup and sync options
So I recently lost all my music and luckily had backed it up some time ago so I have downloaded all my music and wish to back it up again. The problem is I cannot find out how. I have plugged in my ipod and see the Ipod nano on the top. Right under this is 'options' but no back up option. I checked under the tabs at the top - summary, music, podcasts, photos and info but none contain a back up option. In addition, on the side bar, I right clicked my device but even there no back up option is offered. Any ideas?
