The main distinction is security and scope: Unencrypted local backups exclude sensitive personal credentials for security reasons—meaning saved Wi-Fi passwords, Health/Activity data, Bluetooth pairings, Call History, and saved Keychain passwords will not be backed up. Encrypted backups use AES-256 encryption to lock the entire backup image, storing all health records, passwords, and tokens intact. Learn more on Apple Support Security Guidelines.

To enable local encryption: Open Finder (Mac) or iTunes / Apple Devices app (Windows), select your device in the sidebar, check the box for "Encrypt local backup," and set a password. Important: If you lose or forget this backup password, Apple cannot reset it, and you will never be able to restore that backup file!

When migrating to a brand-new iPhone, restoring from an Encrypted Backup saves hours of setup time because you won't have to re-enter Wi-Fi passwords, log back into banking apps, or pair your Apple Watch again. Unencrypted backups force you to re-authenticating almost every app individually.

In terms of raw backup file size, both types consume a similar amount of drive space on your computer's SSD/HDD. However, encrypted backups scramble the file structure on disk, preventing unauthorized local users or malware from extracting sqlite databases containing your SMS messages, WhatsApp chats, or call logs.
