Be prepared for some frustration, though, because as we've made clear iCloud's tier scheme is in need of an update. There are a few things you can do to free up space, and if you can't make room you do have a few options for saving money on an iCloud storage upgrade.
How much you need will depend on how much data you have stored on your iPhone, but you'll get a notification if your storage isn't big enough when you initiate the back up. Of course, you will have to make sure you have enough storage in your iCloud account. The same applies for upgrading to a new version of iOS, just in case something goes wrong. It's also smart to make sure your data is all backed up when it's time to upgrade phones so y ou can set it up in a snap from the data in iCloud. That makes backups one of the best uses of spare iCloud storage. Even if you already have backups on multiple physical hard drives, backing up to iCloud gives you an all-important offsite backup. In fact, we recommend keeping multiple copies of anything you backup so that if one method fails for some reason you still have another. Having backups of your data is a good idea no matter where you store it. You have items stored on your device that you don't want to lose if your iPhone becomes lost, stolen, or inoperable. Backing up your iPhone is just as important as backing up your computer.
