Whether it’s photos, messages, contacts, app data, or important documents—having a backup ensures you’re covered if your iPhone is lost, damaged, or needs to be reset.

What Does a Computer Backup Include?
When you back up your iPhone to a computer (especially an encrypted backup), it saves:
- Photos and videos (if not stored in iCloud)
- Messages and iMessages
- App data and settings
- Home screen and layout
- Contacts
- Calendars
- Notes
- Safari data
- Health data and passwords (encrypted only)
- Voicemail and call history
Music, movies, and apps are usually not included in the backup but can be synced separately from your iTunes library.
Encrypted vs. Unencrypted Backups
🔐 Encrypted Backup (Recommended)
- Saves Wi-Fi settings, website history, passwords, and Health data
- Secured with a password
- Ideal for restoring a device with full personalization intact
🔓 Unencrypted Backup
- Quicker but less secure
- Doesn’t include passwords or sensitive app data
- Fine for general use but not ideal for a complete restoration
You can choose encryption in Finder or iTunes by checking the “Encrypt local backup” option and creating a secure password.

How Often Should You Back Up?
It depends on how frequently your data changes.

- At a minimum, back up before major iOS updates, device upgrades, or resets.
You can also schedule regular backups using macOS Automator, Windows Task Scheduler, or simply set calendar reminders to do it manually.

Managing and Deleting Old Backups
Over time, backups can take up significant space on your computer.
