Apple has released iOS 27 for iPhone 11 and newer models, prompting experts to recommend creating a local, archived backup on a computer before installing the major software update.

Key Points

• iOS 27 is now available for iPhone 11 and later, preceding the upcoming iPhone 18 Pro and iPhone Duo releases.
• iCloud backups are insufficient for major OS transitions because they overwrite previous versions and cannot be used to restore data if a user downgrades their software.
• Users should create a local backup via Finder on Mac or the Apple Devices app on Windows to ensure data remains accessible if the update fails.
• Archiving a local backup prevents the system from automatically overwriting or deleting the data during subsequent syncs or when disk space is low.
• Enabling "Encrypt local backup" preserves sensitive information like saved passwords and Health app data, though it requires a user-managed password.

Why it Matters

Creating a permanent archive provides a critical safety net that standard cloud backups cannot offer during major operating system migrations. This practice ensures users can successfully restore their devices to a previous software version without losing personal data or account credentials.
