Q: Why Wont my phone backup to my computer, it only gives me a option to restore.

Hello there JL Mech,

It sounds like you cannot backup your iPhone to iTunes for some reason. Try the steps in this article:

Get help making a backup in iTunes

If that doesn't work can you elaborate on what your iPhone is showing or iTunes is showing, any other details?

Thank you for using Apple Support Communities.

Take care,

Sterling
