text: **Notes:**Generally, create at least one extra copy on another USB flash drive for storage in 
  a secure location. You can also copy the encryption key from the USB drive and store the 
  data on other media, which can provide extra resilience and mitigate risk that the USB 
  drives used to store the encryption key come from a faulty batch. 
  
  Every encryption key copy must be stored securely to maintain confidentiality of the 
  encrypted data.
