The first I heard of this issue was back in the 1980s when the Government of Canada wanted banks and companies to store data within the country and not in the US where it was cheaper. One of the arguments was the need to simplify access to data for law-enforcement purposes. Technology has changed much, but the issues remain the same. Now it’s the United States Government that wants access to data stored by US companies wherever the data is. Russia wants all companies operating in Russia to store data within Russia.
