Abstract
A subset of data encryption keys are stored in plain text form in system memory of an information handling system. A master key and another subset of the data encryption keys are stored in a credential vault of the information handling system. The credential vault forms part of an out-of-band management platform and is protected by an AES key. A request is received for a data encryption key to decrypt a unit of data backed up to backup storage of the information handling system, the unit of data having been encrypted by the data encryption key, and the data encryption key having been encrypted by the master key and stored at the backup storage as an encrypted data encryption key. One or more locations are checked for the data encryption key. The one or more locations include the system memory, credential vault, and backup storage.
