Guest post
Every travel photographer has the same nightmare. You are a week into a trip, the best light of the journey is behind you, and the card holding all of it refuses to mount. Or a bag goes missing on a night train. Or a laptop disappears from a café table, taking the only copy of a week's work with it.
The encouraging part is that losing photos on the road is almost entirely preventable. It takes a little kit, a routine you can follow when you are tired, and a realistic view of what your connection can and cannot do. This guide covers how to back up in the field, how to choose between a laptop, a tablet and a phone, when to use hotel Wi-Fi and when to use mobile data, how to upload and share without exposing your accounts, and roughly how much data all of this involves.
Adapt the 3-2-1 rule for travel
The classic backup rule is simple: keep three copies of your files, on two different types of storage, with one copy somewhere else entirely. At home that usually means the original files, an external drive on the desk and a cloud copy. On the road the principle still holds, but you have to translate it.
Copy one is the camera card. It is your original, not a backup, even though it feels reassuring to see it in the bag.
Copy two is a portable SSD or rugged drive, or the internal storage of your laptop or tablet, filled the same evening you shoot.
Copy three is off-site. On the road, that realistically means a cloud copy or, at a push, a drive handed to someone you trust or posted home.
The part travellers neglect is location. A laptop and an external drive in the same rucksack count as one copy as far as theft, spilt coffee or a dropped bag are concerned. Carry the drive in a different bag from the computer, or keep one on your person and leave the other in the room safe.
Be honest about the limits, too. On a trip with patchy connections, the cloud copy may lag behind by a day or two. That is fine. The rule is a target, and the real aim is simply never to have a day on which only one copy of your work exists.
Card management: habits that save photos
Most losses on the road start with a card, so it is worth being strict about how you handle them.
Use several moderate cards rather than one enormous one. If a card fails, you lose part of a day rather than the whole trip.
Do not reformat in the field until the files exist in at least two other places and you have checked them. Where you can, keep full cards as they are until you are home. They are small and light, and they make a perfectly good extra copy.
Format in the camera, not on the computer, so the card structure suits your body.
Avoid deleting individual frames on the camera. It is slow, it drains the battery and it is easy to remove the wrong shot on a small screen. Review properly on a bigger screen in the evening.
Use dual card slots if you have them. Write RAW to both for an instant in-camera copy, or RAW to one and JPEG to the other for a quick, shareable version.
Keep cards in a labelled case, with full ones facing one way and empty ones the other. Never leave them loose in a pocket.
Check, do not trust. After importing, compare the file count with the card and open a few images at full size. If your import software offers verification, switch it on.
Laptop, tablet or phone: pick the workflow you will actually follow
There is no single right answer, only the one you will still be following on day nine.
Laptop. The most capable option. It reads cards quickly, runs full editing software, handles a proper catalogue and connects to a portable SSD with no fuss. The downsides are weight, battery life and the simple fact that it is an attractive thing to steal.
Tablet. A good middle ground. Many tablets take a card reader or drive through USB-C, and the screen is excellent for culling and light editing. File management can be fiddlier and some software is more limited, but for a nightly "import, check, back up" routine it is often enough, and it is much lighter than a laptop.
Phone only. The lightest option, workable with a compact card reader or with a camera that can send images to the phone wirelessly. It suits JPEG shooters and short trips. The catch is that your phone is also your map, your boarding pass and your camera's remote control, so losing it costs you twice. If you go phone-only, pair it with a small SSD so that the card is never your only copy.
Whichever you choose, keep the order of operations the same every night: import, verify, copy to a second drive, cull, export what you want to share, then queue the cloud upload. A twenty-minute routine you can do half asleep beats a perfect system you skip.
Cloud backup: hotel Wi-Fi or mobile data?
Both have a role, and the trick is to give each the job it does best.
Hotel Wi-Fi is usually the better home for the bulk upload. There is no data allowance to worry about and you can leave the laptop running overnight. Against that, quality varies enormously, sign-in pages time out, many guests share the same line, and it is a network you do not control, which matters for the security reasons covered below.
Mobile data is steadier and more private, but an allowance is an allowance. It is best used for targeted uploads, such as your selects, a handful of resized JPEGs or a shared album for the family, rather than the full RAW archive.
A simple two-tier approach works well:
Tier one: selects, the same evening. Send your best frames and any edited exports over whichever connection is most reliable that night.
Tier two: the full archive, when conditions suit. Let the complete set upload overnight on a network you trust, or on a shared network once you are signed in over your own connection, since reputable cloud services encrypt what they send. If the line keeps dropping, wait until you reach somewhere with a better connection, or home.
Set your upload software to pause on mobile data and resume on Wi-Fi so that you never use up an allowance by accident. Keep the laptop plugged in and stop it sleeping. Check that the uploader can resume after an interruption, because on hotel networks it will be interrupted. Finally, look at the cloud service's web page now and then to confirm that the files really are there. A progress bar is not proof.
Staying connected with a travel eSIM
Hotel Wi-Fi is hit and miss, and cafés and airports are often worse. A travel eSIM gives you mobile data that does not depend on the building you happen to be in, so you can send selects, message family and approve sign-ins without sharing a network with strangers.
An eSIM is a digital SIM profile, so there is no plastic card to swap or lose, and your home SIM can stay in the phone alongside it. Use the eSIM for mobile data and switch off data for your home line, including any option to use data abroad, so that it cannot run up charges by accident. If your phone asks, allow data on the eSIM line. Your phone must support eSIM and not be locked to a network, so check before you travel.
Simbye, for example, offers travel eSIMs for more than 190 countries. You buy online and install the eSIM with a QR code or a link before you leave, so you land connected. The validity period starts when you first connect at your destination, so setting it up at home does not use up any of your days, as long as you leave the eSIM line switched off until you land. On multi-country trips, the app can combine countries on one eSIM. Simbye also offers separate US, UK and Australian mobile numbers whose texts and verification codes arrive in its app, one more route for sign-in codes if a service lets you register such a number.
How much data are we actually talking about?
Rather than guess, do the arithmetic. File sizes depend on the camera, but typically they look like this:
File typeTypical size per frame300 frames, as a worked exampleCompressed RAW (24 to 45 megapixel camera)Around 20 to 60MBAbout 9GB, if you assume 30MB eachFull-size JPEG from the same cameraAround 5 to 20MBAbout 3GB, if you assume 10MB eachPhone photoTypically a few megabytesJust under 1GB, if you assume 3MB eachResized JPEG for sharing (around 2,000 pixels on the long edge)Typically a few hundred kilobytes to about a megabyteAbout 150MB, if you assume 0.5MB each
The sums are simple: 300 frames at 30MB is 9,000MB, or about 9GB. The same 300 frames as resized JPEGs come to about 150MB, a small fraction of that.
A busy shooting day can therefore mean gigabytes of RAW files but only a few hundred megabytes of shareable images. That gap is the whole argument for the two-tier approach. It also shows why shooting RAW plus JPEG matters: it adds a second file to every frame, so decide deliberately whether you need both.
Edit offline, share when you are ready
Treat editing as something that never needs a connection. Keep your catalogue and your files on the SSD or the local drive, cull and edit there, and export finished JPEGs to a folder with an obvious name such as "to share". Your upload queue then becomes simply that folder, and a poor connection can never hold up your work.
A few habits make this smoother:
Back up the catalogue as well as the images. Your edits live in the catalogue or in small sidecar files. They are tiny compared with the pictures but just as precious. Keep sidecar files beside the originals so that edits travel with them.
Organise by date and place from the first evening, for example the date followed by a location. Captions and keywords can wait until you are home.
Edit in short sessions. It is tempting to polish a favourite frame for an hour and then skip the one job that matters, which is the backup.
Never edit on the only copy. Work on files that already exist on a second device.
Offline editing also saves battery and data, because nothing is syncing in the background while you work.
Public Wi-Fi: upload without handing over your accounts
Treat every shared network, whether in a hotel, an airport or a café, as untrusted. Other guests are on the same network, badly set-up routers can expose more than they should, and look-alike hotspots with convincing names exist. Sensible habits cost you very little:
Confirm the network name with reception rather than joining whichever one looks plausible.
Prefer mobile data for sign-ins. Log in to your cloud and social accounts on your own connection where you can, then let the long upload run on Wi-Fi once you are signed in.
Be wary of pop-ups. A hotel's sign-in page may ask for a room number. It should never ask for your cloud, email or social password.
Use a reputable VPN on your laptop and tablet when you have to rely on a shared network. Modern apps already encrypt their traffic, and a VPN adds another layer, particularly for the less obvious details such as which sites you are visiting.
Switch on two-factor authentication before you leave, and do not rely only on a text message to your home number, which may not arrive abroad. Use an authenticator app, save backup codes somewhere offline, or add a second number on which you can receive texts.
Encrypt your drives. Full-disk encryption on the laptop and the portable SSD means a stolen bag is an inconvenience rather than a data breach.
Keep software updated, turn off file sharing and forget the network when you check out, so that your device does not rejoin it automatically.
Sharing with family and on social media
Sharing is where many photographers waste data. Nobody at home needs a 40MB RAW file, and social platforms recompress whatever you send them anyway.
Export small. A JPEG of around 2,000 pixels on the long edge is plenty for a phone screen and uploads quickly even on a modest connection.
Use one shared album for the family, set to invite-only or link-only, and add to it as you go. It beats dozens of separate messages, and relatives can look when it suits them.
Strip location data from anything you post publicly, especially frames taken at your accommodation. Most export tools have a switch for it.
Post a little behind real time. Live updates tell the world that your home is empty. Many photographers post a day or two late, which also lets you send from the Wi-Fi at your next stop.
Add your copyright details to your import or export preset once, and every file carries them without extra effort.
Move photos to your phone deliberately. Send exported JPEGs from the camera over its wireless link, or transfer them from the laptop, rather than syncing the whole library.
A nightly routine that holds up
Put it all together and an evening on the road looks something like this:
Take the card out and put it in the "full" pocket of its case.
Import to the laptop, tablet or SSD, and compare the file count with the card.
Copy everything to a second drive that lives in a different bag.
Cull, rate and make quick edits, working offline.
Export a small set of JPEGs for sharing, with location data stripped.
Queue the selects for upload, and leave the full archive for a trusted network or later.
Check that the upload finished and make a note of anything still pending.
Only reformat a card once every file on it exists in at least two other places, and ideally not until the trip is over.
Once a week, open a file from each copy to prove that it really works.
The short version
Backing up on the road comes down to three ideas: never rely on one copy, give each connection the job it suits, and keep what you share small. Do those, and a failed card or a lost bag becomes an irritation rather than a disaster. Spend half an hour before you leave testing your card reader, your drive and your upload settings, and your best pictures of the trip will still be waiting when you get home.
