A third party facilitates preparation of a backup SSD for backing up a source SSD. Digital data of the source SSD, which includes protected and sensitive data and information, is copied to the backup SSD either by and via the third party or directly from the source SSD but under supervision of the third party. The digital data of the source SSD is copied to the backup SSD under stringent rules and only if each party (i.e., the source SSD, destination SSD, and third party) proves to a counterpart device with which it operates that it is authorized to send to it digital data or to receive therefrom digital data, depending on the device with which that party operates.
