Backing up your iPhone to a computer is one of the safest ways to protect your data. Unlike iCloud, which depends on storage space and internet, a computer backup keeps everything local, photos, messages, app data, and settings. Whether you’re using a Mac or Windows PC, the process is straightforward once you know which app to use.
