The safest way to back up iPhone data before the iOS 9 update is to back up iPhone data to Mac ( iPhone data can also be backed up to Windows PC, Which will be demonstrated with another article. ) and there are a couple of ways to achieve so, syncing your iPhone to iTunes to create an iTunes backup file and exporting iPhone data and transferring to computer for backup through third party software iFonebox. As iTunes crashes from time to time and iTunes backup file may be damaged, I am suggesting to create additional and alternative backup for your iPhone before the iOS 9 update.
Since Apple has illustrated with details about how to sync iPhone to iTunes and create iTunes backup file, I am not going to repeat the steps. Instead, I am going to introduce how to back up iPhone to Mac before updating to iOS 9 through iFonebox.
As professional iOS data recovering and transferring software, iFonebox offer s three different options to export the iPhone data including exporting and transferring from iDevice, iTunes and iCloud backup file. Here I am going to show you the steps about how to create iPhone backup before iOS 9 update by exporting and transferring all supported iPhone data directly from iPhone to Mac computer.
You can download a free trial version to have a try but you need to pay for the full version.
Now let’s get down to the detailed steps.
Step 1: Install and Connect
Install the full version of iFOnebox and launch it. Please make sure that you have download the right version as there are two versions of iFonebox, the Windows version and the Mac version, choose the right version according to the computer and the operating system you are using. Then connect your iPhone to your Mac computer and click the popped up button of “Start” after your iPhone is recognized by iFonebox. Tips: If your iPhone is not detected by iFonebox, please check whether you have unlocked your iPhone with the passcode, and whether you have hit “Trust this computer “on your iPhone screen.

Step 2: Choose Data Category
iFonebox will show you an interface listing all the supported data categories for you to choose. Click on the data category you want to export and transfer. If just want Contacts or notes or messages or photos only, for example, you can just click on the icon for the data category selectively. Or if you want to export and transfer all the supported data to your Mac computer for backup before the iOS 9 update in case of accidental data loss, check the box at the upper left named “Recover All”.

Step 3: Define Destination Folder and Transfer
The destination folder for the exported iPhone data can be self defined. Or you can just use the default folder. All the exported iPhone data from your iPhone can be transferred to your Mac computer by hitting the button “Recover to Mac”.
After the transferring finishes, the iPhone data is successfully backed up to your computer before the iOS 9 update. You are free of worrying about losing data accidentally due to the iOS 9 updating.
