iOS 8 Health data: backup and iCloud
I hat to bring in my iPhone for repair and I backed up all the data on iCloud and with iTunes (just to be sure). I then got a replacement phone for one week.
I was not able to recover my Health data:
The data seems not to be synchronised with iCloud (no other device as my iPad or the replacement phone see anything)
The data was not backed up. I got everything back but for the Health data
Is there a way to back Health data up?
Looks like you need to encrypt your iPhone backups for your local backups to retain health data:

Hope this helps?
Update: iOS 11.0 has an option to sync Health.app data instead of just backing it up. So now you can perform a clean install and still have your health data.
iOS 8.0 doesn't backup Health.app data to iCloud but iOS 9 does.
You can save the information stored in your Health app by backing up your iOS device with iCloud. Your information gets encrypted as it goes between iCloud and your device, and while it's stored in iCloud. If you aren't using iCloud, you can back up your Health information by encrypting your iTunes backup.
