Why is 1TB of storage being used for health app?

Nope- After the 10 Nov event they will focus on this hopefully

Would backing up my phone to my external hard drive work?

Wow - Petabytes.

You are either incredibly healthy or very very unhealthy.

:D

Calling apple in 15 minutes, a couple days ago they tried to fix it but they couldn’t, they contacted engineering and they’re gonna call me in 15 to try to fix it, I’ll keep you posted

Any updates?

Did you try it?! Did it work?!

Everything is fine finally. Thank you Apple, you are the best!😁

Yes it did!!

Hm, storage issue fixed. Just lost all my health and activity data, on Apple support rn but not seeming useful.

After 14.2 you lost all the health activity data ? Did you have to repair your watch after the update?

Just to clarify, your data was gone after you installed iOS 14.2?

Update - woken up today and everything is back with the only change being an iCloud backup happened yesterday, didn’t even update my watch. No storage bug either so I’ll leave it at this. Thanks all.

I discovered this while trying to get this phones data to transfer to a new phone and it said not enough storage on the new iPhone. They might have fixed it though so I don’t know anymore.

Have you updated to IOS 14.2

UPDATE: Apple Support confirmed the believe it is an software issue with the new updates.

Advice was to backup the phone to mac/pc and factory reset. Restore backup, the re-pair the watch.

I hit a roadblock immediately as the backup wouldn't work as the Mac is reading the backup size as over 1TB and doesn't have enough space. At the moment I've restored and am backing up from a cloud back up made 2 days ago - fingers crossed so far, the storage issue appears to be resolved with the Health App just having around 225MB (which is more like it!)
