Guide
Before a trip
Start the first backup at home, not at the gate.
One
Home Wi‑Fi, two nights.
Two
Travel on Wi‑Fi in rooms.
Three
Do not flip cellular 'just this once'.
Before a trip sits inside a simple product: original-quality iPhone backup, quiet on Wi‑Fi, a restore that brings the dates back. Not a feed. Not a compressed cousin.
You set it up once in the iPhone app. New photos leave when the phone is calm. If the handset dies, you sign in on the next one. That is the whole job.
