18 Master keys The key is divided among the cards in the card set, up to 10. The quorum of cards required to restore the master key must be less than the total number of cards in the set, and no greater than five. For example, when the master key is backed up to a set of three cards, a quorum of any two cards can be used together to restore the master key. When the master key is backed up to a set of 10 cards, a quorum size of up to 5 cards can be configured for restoring the master key.. Backing up the master key to multiple recovery cards is the recommended and most secure option. NOTE When you write the key to the card set, be sure you write the full set without canceling. If you cancel, all previously written cards become unusable, and you will need to discard them and create a new set. 1. Select Configure > Encryption from the menu task bar.
