I really wouldn’t give a shit.
My biological parents were both worthless parents.
The guy who raised me wasn’t my biological father.
I adopted my son.
The only “issue” with not knowing your biological parents is the lack of family medical history, but that really is not big deal.
I wouldn’t do tape. If you don’t want a cloud option, why not use use a thumb drive?
If you are willing to do tape, you can store a thumb drive into same way.
