Most travellers carry one set of important documents (passport, insurance, travel itinerary). Loss or theft becomes serious crisis. Having second set — with trusted person at home, accessible via secure cloud — makes loss inconvenient rather than crisis.
What to duplicate
Passport photo page. Travel insurance details and emergency phone. Visa documents if relevant. Vaccination certificates. Flight bookings. Hotel reservations. Emergency contact list.
Where to store
Cloud storage (encrypted). Email to yourself. Trusted family member with copies. Phone photos for immediate access.
Five minutes before each trip; potentially trip-saving if needed.
