It sounds like overkill to me. I just take pictures of my important health records and save them in a secret email account. In the same account, I store pictures of my credit cards (front and back), Identification, etc.
I also keep the health record pictures on my computer, since there is nothing there I am worried about getting stolen.
They really are not that complicated. What is more important is that you understand them and communicate this to your physicians overseas. For instance, knowing your prescriptions and the reasons for them, etc.
Also, you may have to get used to asking for your records. When I left Kaiser insurance in the USA, I asked for copies of all my records, which they thought was a strange request (and I had to pay some nominal fee I think). But I wanted them mostly to help me apply accurately for private USA health insurance. Overseas, you will find that most medical professionals are more cognizant of giving you your medical records.
I don't actually ever give these records to overseas doctors or dentists that I see (admittedly, I am healthy). They are mostly for my own recollection, and I communicate what I know to any medical people overseas. For instance, if I was going in for a physical, I would make a note of any abnormal blood test readings from last year. I took a picture of each page of last year's report (I don't actually travel with any records in paper form).
If you have an HSA account, you will want to keep receipts and spending records for your taxes. I also take pictures of these once a year and store them and I keep the paper in the USA.
