You probably have exported Apple Health data to a computer. There is no separate option for archiving this data on an iOS device without using the export option.
- Exported Data (ZIP/XML):
- When you use Export All Health Data in the Health app, you get a ZIP file containing XML records.
- This file is intended for viewing, analysis, sharing, or archiving purposes only — Apple does not provide a method to re-import it into the Health app.
- In other words, you can’t “restore” Health data from this export onto a new iPhone.
- Export = archive only (good for safekeeping, sharing, or analysis).
- Backup = restore (the only official way to get Health data back into a new iPhone).

Go to the Settings app on your iPhone · Tap your name, then tap iCloud. · Tap Show All, tap Health, then turn Sync with iPhone on or off.
