PCI audit - the auditor wants to SEE the encryption.
Not just verify that KEYS exist, not test backup and restore, with and with out keys.
He wants to see the data on tape using OS commands, and then see what it looks like once keys are deleted.
Do you know your OS commands to write data to tape and read it back? I did 10 years ago, lol...
