  1. Data Integrity
  2. Regular update of data
  3. Validation of data
  4. Security of data/Encryption
  5. Type of Data
  6. Type of storage to be used
  7. Data volume/Size
  8. Access Control

  10. Limit Physical access to storage media
  11. Regular Backups
  12. Ensure Data Recoverability
  13. Login/Password 
  14. Record Date and Time   
  15. Power Supply
