WIPING a country off the map is one thing. Wiping its data is another.
Estonians know what the former is like. They are determined to avoid the
latter. Just as computer users back up their laptops in case they break or
are lost, Estonia is working out how to back up the country, in case it is
attacked by Russia.

Estonia has already shown notable prowess in putting government services
online. It has pioneered the use of strong digital identities for every
resident, enabling them to sign and encrypt documents, access government
services, and conduct e-commerce.
