EBS does not re-encrypt all the data once the key material got rotated. But … IDK

Possible answers, but not so sure

  • Theres a long master key which is used to encrypt data but then this key is encrypted by operational keys
  • EBS tracks which blocks of data gets encrypted with the respective key material
