There was some more discussion around Transparent Data Encryption.
I am assured by the architect that the business understands that they will lose data if the key is ever lost.
This assurance seems to me to be a lot like when a business makes its first business continuity plan. Everyone understands that it will take time and effort. Then they scream loud and clear when a business continuity exercise is actually done. They could not make the leap from what they were told to what they experienced.
