Backup and file safety for concert photographers

Back up concert photos before you leave the venue if the camera has two card slots, then copy to two separate drives the same night, one of which lives elsewhere or syncs offsite. Never format a card until both copies have been opened and checked, not merely seen to exist.

You can re-shoot almost anything except a live show. Losing a card is not a technical failure — it is a career failure, and it is avoidable.

Updated 10 August 2026·By Paul Visions

A concert is unrepeatable. The frames on your cards are the only record of a moment that will not happen again. A redundant, boring backup workflow is the single most important insurance policy in this job.

The rule of three

At every stage, aim for three copies in at least two places:

Two copies on the same device do not count as two copies.

In-camera habits

Use multiple smaller cards rather than one huge card. A lost 64 GB card is a lost night; a lost 32 GB card is half a night. Format each card in camera before the show, not on the computer — this reduces file-system errors. If your camera has dual slots, write the same image to both cards simultaneously. That one setting turns a card failure from a disaster into an inconvenience.

On location

If you have a laptop or a portable backup device in your car, copy the cards before you leave the venue. If you do not, keep the cards on your person, not in a bag that can be left behind. Do not put freshly shot cards in the same pocket as empty cards; the mix-up is easy and expensive.

The ingest workflow

When you get home, copy the files before you look at them. The temptation to open Lightroom first is strong; resist it. Copy to two locations, verify the copy — most ingestion tools can compare checksums — and only then format the cards or start culling.

Keep raws until delivery is complete and payment is settled. The raw file is evidence of authorship and your only protection if a usage dispute arises.

At-home storage

A single external drive is not a backup. Use at least two drives, with one kept off-site or in cloud storage, and rotate them. For working photographers, a small NAS with two mirrored drives is a reasonable step up. For most people starting out, two portable drives and a cloud account are enough.

What to delete and when

Delete obvious mistakes immediately after culling — out-of-focus frames, blown exposures, duplicates. Keep the raw keepers for at least the duration of the project. Many photographers keep all raws for a year or more, then archive a selection. There is no single right answer, but deleting raws the same night is usually a mistake.

Travel and festivals

On the road, redundancy matters even more. Copy cards to a laptop and a portable drive each night. Upload a small selection to cloud storage when bandwidth allows. Do not travel with all your cards and your only backup drive in the same bag.

Common questions

Should I format cards in camera?
Yes. Formatting in camera reduces the risk of file-system corruption that can happen when a computer formats the card.
How many cards should I carry?
More than you think you need. For a long night or festival, several smaller cards are safer than one large one.
Is cloud backup fast enough?
For a small selection or a fast connection, yes. For hundreds of raw files after a festival, a local drive is faster. Use both.
Should I keep raws forever?
Keep them at least until the job is delivered and paid. Many photographers archive raws for a year or more.
What if a card fails?
Stop using it immediately. Recovery software sometimes works; professional recovery is expensive but possible. Dual-slot recording makes this question much less frightening.
