Good idea, thanks for the suggestion. It does seem more open for the appliance to ship data to the cloud and also the reverse. The interest is interesting, and I'll definitely feed that back.
Another idea would be for GCP to handle export to a physical device and that device would be shipped to a known location (to both GCP and the client) and accessible by either but offline and cold stored. And similar to how paper records are stored you could put in a request to access the records and thereby verify their existence (which you can't do with cloud data other than the copy that you are able to access).
Fwiw, Iron Mountain lost about 60 physical records file boxes that we had ..
Shipping Petabytes to a cloud you can practically never again retrieve all the data is ... risky.
The aws way of doing this is nice: You rent the appliance like when importing data to the cloud and pay a (reduced) "bandwidth" fee for exporting the data to the appliance which will be shipped to you.
