Backing up your iPhone is important for keeping your data safe. You can back up using iCloud by going to Settings > [your name] > iCloud > iCloud Backup, then tap "Back Up Now." Alternatively, use a computer: connect your iPhone to your computer, open Finder or iTunes, select your device, and choose "Back Up Now." Have you backed up your iPhone before, or is this your first time doing it? How do you feel about managing your backups? I'm here to help if you have any questions!
