Worried about iPhone backup?
So the other day my screen shorted out (I'm guessing, the issue is still undiagnosed.) iTunes on my PC says, under "This Computer," "Latest backup: (Two weeks ago). This is good news for me, but I don't quite trust it. I'm wondering if all this time it's been automatically updating like it says, even so, I have no idea where these photos are located on my computer.
After contacting Apple they have told me I need to restore my phone and see if it helps. I'm afraid of losing everything. Luckily I do have a SIM card, but I know that they only hold contacts. How do I know iTunes is correct that my photos have been backed up? How do I locate the photos? Is it safe? Will I lose them if I restore even if it says they've been backed up?

Added (2). I have never used iCloud backup, but under the option for iCloud backup reads "This Computer"
