Hi Martin, Backup up your iTunes library is as simple as copying your 'iTunes' folder. For instance, you can open your 'Music' folder and drag-and-drop the 'iTunes' folder icon onto your external hard disk icon.
Of course, this will take a very long time because you have 400 GB of music, and maintaining this backup would require that you copy the whole 400 GB every time you make a backup. Therefore, you may prefer to use backup (sync) software instead. Backup and sync software works by detecting changes, and only needs to back up the new/changed files. If you ever need to recover your iTunes library, you can simply drag the backed up 'iTunes' folder back to your Music folder. Alternatively, if you wanted to point iTunes to use the external disk instead of your internal disk, open iTunes and hold then down the Option key as soon as possible. iTunes should ask you whether you want to Quit, Create a New Library, or Open A Library. You can choose Open... and select your external iTunes folder. iTunes will remember this setting.
