Now that iOS 26.1 is out, you might be more comfortable updating to Apple’s latest iPhone operating system. Or maybe it’s time for a bigger upgrade to a new iPhone 17, iPhone Air or iPhone 17 Pro? Before you do, take a little time to ensure you’ve made a good backup you can fall back on just in case something goes sideways.
I’m not talking about any regular backup, though. Hopefully, you already have your Apple Account settings configured to automatically back up the phone to iCloud, which is invaluable for everyday peace of mind. I’m talking about creating an archive that can save your hide in the unlikely event something goes wrong with the iOS 26 update.
You’re probably accustomed to using iCloud Backup to maintain a regular fallback for your data. It works in the background (when you’re asleep and charging your device) and involves the least amount of backup friction, as long as you have sufficient iCloud storage space available. Go to Settings > [your name] > iCloud > iCloud Backup and turn on Back Up This iPhone if it’s not already active.
However, when it comes to moving to a full release version of iOS, such as from iOS 18 to iOS 26, an iCloud Backup introduces a problem: You cannot restore from that cloud backup if you revert back to iOS 18. And unfortunately, iCloud keeps just the most recent backup — you can’t pick and choose from previous backup iterations. If you try to use an iOS 26 cloud backup to restore back to iOS 18, you’ll get an error. (Making an archive is also an important step when you install iOS betas.)
This is why you need to archive a backup on your computer.
Create an archive backup of a connected iPhone on the computer (MacOS shown here).
Taking the extra step of marking the backup as an archive protects it from being overwritten by the next local backup or automatically deleted if the Mac is low on space.
