WEDDINGS → BACKUP

What backup workflow protects a wedding you cannot reshoot?

Two slots, two bags, one habit: the on the day backup workflow as a checklist, the same night ingest, and the rule about when cards may finally be formatted. Nothing here is optional; the wedding happens once.

KEY TAKEAWAYS

The whole discipline is one sentence: from the first frame to the delivered gallery, the wedding exists in at least two places at every moment.
Dual card slots write duplicates, not overflow. Overflow doubles capacity; duplicate doubles survival, and survival is the one being purchased.
The same night ingest is not optional and not tomorrow: both copies onto two separate drives before you sleep.
Cards are formatted when the gallery is delivered, and not one day before. Until then they are the third copy.

The principle: two places, always

Every backup rule in this chapter derives from one principle: at no point between the first frame and the delivered gallery does the wedding exist in only one place. Check any workflow against it and the gaps announce themselves. One card per camera: the wedding exists in one place all day, fails. Duplicate slots but both cards riding home in the camera bag: one stolen bag is one wedding, fails at the car door. Ingested to a single drive and cards formatted for tomorrow’s shoot: one dead drive, fails. None of these failures needs bad luck to happen twice; each needs it to happen once, to an event that cannot be reshot at any price. The checklist below is just the principle applied hour by hour.

During the day

CHECKLIST · ON THE DAY (PRINTABLE)

Both bodies set to write duplicates to both slots, verified with a test frame and a chimp of BOTH cards, the week before and again in the car.
Cards formatted in the camera that will use them, before the day, never on it.
Full cards go in the second bag or a zipped pocket on your body, never back into the card wallet with the blanks, and the wallet never sits unattended.
Swap cards at natural breaks with margin remaining, dinner, the lull before the entrance, not at 2 percent during the toasts.
If a card errors mid day: stop using it, do not format it, do not retry it in another body. Label it, pocket it, switch to fresh, recovery happens at a desk, not a reception.
Batteries and cards live in the same pockets every wedding, so your hands know where everything is in a dark room.

The same night ingest

The drive home is the riskiest hour of the workflow, one bag in one car containing every copy, which is why the ingest happens the same night, tired or not: copy slot A cards to the working drive, copy slot B cards to a second, physically separate drive, verify both copies opened and counted, and only then sleep. Counting matters more than it sounds: a copy that silently dropped a folder looks identical to a finished one until you compare frame counts. If your habit includes an offsite or cloud copy, start it tonight too and let it run; the classic three copies, two kinds of storage, one offsite shape exists because house scale disasters do not respect two drives on the same desk. The cards themselves go into a marked envelope, untouched: they are now the third copy, and they hold that job until delivery.

Until delivery, and the formatting rule

Through the edit, the two drive rule holds: the working catalog on one drive, a synced copy on the second, refreshed at every major milestone, cull done, edit done, export done. Export the finished gallery to both drives, deliver per the delivery chapter, and confirm the couple has downloaded it, most gallery hosts show you. Then, and only then, the cards from the envelope get formatted back into rotation, and the delivered gallery keeps living on two drives for however long your contract’s archival clause promised, a promise this workflow is what makes honest. The couple asking for one lost frame eight months from now is a small favor; the couple asking for a wedding a dead drive ate is the phone call this chapter exists to make impossible.

Frequently asked

My camera has one card slot. Can I still shoot the wedding?

People have and do, and the honest accounting is: the wedding exists in one place all day, which violates the principle at its first line. If the booking matters, rent a dual slot body for the weekend, it is the cheapest insurance in photography, and the spine guide already argues the second body case for other reasons.

Big cards swapped rarely, or small cards swapped often?

Both positions are defensible and photographers argue it endlessly: big cards minimize handling, the riskiest human moment, while small cards cap how much one lost card costs. Pick either, then let the duplicate slots make the debate mostly moot, which is the actual answer.

Is a cloud backup enough on its own?

As the only copy, no: upload speeds make same night completion unrealistic for a full wedding, and an unfinished upload is not a backup. As the third, offsite leg on top of the two drives, it is excellent, start it the same night and let it finish over the following days.
