While using iTunes to back up your iPhone is generally a simple process, it is not a practical solution if you are away from your computer and need to copy your phone’s files to another machine. It is possible to back up files and apps on your iPhone without jailbreaking the device or purchasing software. This is helpful if you are on a business trip and your laptop malfunctions, preventing access to iTunes.
Before you can back up your iPhone on a computer that does not belong to you, you'll need to make sure that the computer does not start iTunes automatically when you connect an iPhone to it. After opening iTunes, choose “Edit” from the program menu and select "Preferences" from the drop-down menu. In the “Devices” tab, make sure that the box next to "Prevent iPods, iPhones, and iPads from syncing automatically” is checked. Connect your iPhone to the computer. If iTunes opens when you connect the device, select the iPhone "Summary" tab from within the software. Uncheck "Automatically sync when this iPhone is connected" in the "Options" section. You also need to check "Manually manage music and videos" in the same section. Close iTunes so you can install other software to manage and back up your iPhone.
