Question

How do I back up my tunes and iPhone Apps?

Answer 1

Assuming you use the iTunes default settings where iTunes copied added items to your iTunes folder and organizes your library (meaning - everything is all self contained in the iTunes folder), then all you have to do is drag & drop your iTunes folder (not just the iTunes Music folder you find inside the iTunes folder) to the external drive and copy the entire thing.
If you want to test that it worked or would like to actually start using it from that location instead, use these instructions when you start iTunes to point it to the new location...

If you are just testing, then close iTunes after you verify it works, and restart iTunes again with the same instructions and point it back to your internal drive (original) location.

p.s. I don't know anything about the iPhone or the iPhone apps so I am not sure if they are stored in the same folder structure or not.
