How to Backup Different iPhones on the Same Windows Computer

 “I and my wife both using iPhones and we just got one Windows computer. Of course, both of us want to backup the phones regularly. But iTunes can not intelligently recognize they are two different iPhones and make the backup. Is there a way to backup two iPhones to one computer?”

I came across this question on the Reddit forum. Many people share their answers to this question. Some said you can just backup the two iPhones to one computer using one Windows account as the data will not be mixed; some said you can just go ahead to set up the second iPhone as the new iPhone and restore the backup because there is no data loss; Some recommends the third-party tool to finish the iPhone data backup. After going through these answers, I also have my own doubt: Can iTunes help to backup different iPhones on the same Windows computer?

The answer is definitely “Yes”.  You can backup different iPhones on the same Windows computer via iTunes. In order to verify this answer, several iPhones in different models are tested here.

Test 1: Backup Two iPhones on One Windows Computer –Both can Easily Back up

In this test, iTunes does not log in to any account. And the two iPhones are connected separately.

Step 1: Connect iPhone 6s with the Windows computer and run iTunes. iTunes can quickly detect the iPhone.

Step 2: Go to click the small iPhone icon and then all information about the iPhone is classified. Hit the Summary tab on the left menu and then get iPhone 6s details and Backups parts.

Step 3: Check the box of This Computer and then click the Back Up Now button. iTunes can help to automatically back up the iPhone 6s data immediately.

Step 4: After the completion, disconnect the iPhone 6s and then connect another iPhone –iPhone 8.  Next, just repeat the operations in Step 2 and Step 3, the iPhone 8 is backed up to the Windows computer in minutes.

Both backup processes is completed successfully and did not come across any issues.  The two iPhone for testing is in the same iOS version.

Test 2: Backup Two iPhones on One Windows Computer –The Second One Needs to Set up as New iPhone

Another iPhone is chosen here for test—iPhone XS.  I plug the iPhone 8 out and reconnect the iPhone XS with the computer. At this time, when iTunes is opened, I only got the Welcome to Your New iPhone window. After choosing to set up the iPhone XS as the new iPhone, iTunes will know this iPhone is another device and create another record. If you insist in restore the iPhone from backup, actually, you will lose all the iPhone data and restore from other iPhone’s backup.

 To get this issue solved, I search online and find the solution: Try to connect the two iPhones in different Windows account and then precede the iTunes backup. It means that you need to create two accounts to sign in to Windows. But in my opinion, I would rather try other ways to backup different iPhones on a computer.

Alternative Ways to Backup Multiple iPhones on the Same Windows Computer

Yes, from the above two tests, it seems that iTunes is not the best choice to backup different iPhones on the same Windows computer. I found the alternative tool—iSunshare iSyncGenius. This software can help to transfer iPhone data to Windows computers quickly and safely. What’s more important, it can separately store the backups for different iPhones even the backup path is the same.  Amazing? Yes, you can backup as many iPhones on one computer safely. Let’s see how it achieves.

Step 1: Connect the iPhones you want to back up to the Windows computer.  It is no need to connect the iPhone separately.

Step 2: Run iSyncGenius and then the backup interface is on.  You can click the drop-down icon on the Device model to choose the iPhone which you want to backup firstly. Here, iPhone 7 is chosen.  After that, click the Next button to continue.

Step 3: In the next interface, All Backups are selected by default. This function is similar to iTunes Backup Now. You can get the listed data backed up after finishing.  After that, click the Choose button and pick the destination to save your iPhone backup data. It can be anywhere on your Windows computer.  When the backup path is set, just go to click the Start button to begin the process.

Step 4: The iPhone data will be backed up in minutes.  Then you can click the Finish button and repeat Step 2 and Step 3 to back up other iPhones.

In the end, you can go to check the backup files in the destination folder. As I saved the backup in the same folder, I can find all those iPhone backups conveniently.

Someone may ask how to restore the backup if you need it. Don’t worry; you can also utilize the Restore function of this software to restore the iPhone backup.
