Abstract
Accessing a data set with secret and non-secret data. A method includes accessing a data set image. The data set image comprises secret data. The data set image is derived from an authorized data set associated with a master key that authorizes access to the secret data. The master key is not provided with the data set image. The method further comprises restoring the data set image to a computing system to create a degraded data set. Data in the degraded data set other than the secret data is accessed without restoring the master key.
