Backup photographs when hiking – Lightweight Travel

Accessing, backing up and editing RAW photographs remotely is something that receives a bit of controversy online. Processors and storage are much smaller than yesteryear, yet dedicated backup solutions for travel photographers are rarely pragmatic and viable. The Lacie DJI Copilot is impressive, but somewhat heavy. I think people have the attitude “why not just use a laptop?” but I have personally found lightweight solutions to be incredible for things like camping.

Having built various networks, servers, desktop computers, and set up nearly every Linux distribution available, etc. I’m fairly computer literate. However, this article might get obsoleted soon; moreover, some of this is subjective and you may prefer to use another method. With this in mind, I am in no way suggesting my methods are a perfect solution to the problem discussed here: how does a travel photographer back up his/her photographs without breaking his/her back, backpack and bank?

An obvious backup solution

The easiest way to backup data is to have a camera with dual card slots and you should factor this into consideration when buying a camera. It is always a good idea to backup data as many times as possible, but the chances of two cards failing at the same time are incredibly slim, especially if you buy your SD cards at a different date i.e. they (hopefully) won’t be from the same batch and if there’s a problem with one production line, it shouldn’t affect you beyond one SD card failing. Another advantage to this method is that if one memory card slot fails to function, the other should continue to work.

The disadvantage with this is that up until recently, cameras with dual card slots have typically been bigger, and more importantly, heavier. This isn’t because they have to be, for example the Sony a7rIII and the Sony a9 are small cameras. Not everyone can afford to buy the Sony a7rIII or the Sony a9 though; many lightweight, small, mirrorless interchangeable lens cameras still have single card slots.

It’s not a perfect solution to have dual card slots either. If someone steals your camera or it fries, you might lose both cards. It’s also worth considering certain models shoot at a slower rate when both slots are used (this is true with the Canon 5d Mk III, Sony a7rIII, sony a9, etc.) and this may screw with your shooting style. Nonetheless, I believe dual card slots are the best portable backup option for a travel photographer especially if you combine it with an SSD.

A dedicated device: perhaps the worst option for travel photography

An external storage device can be useful for duplicating data; these are somewhat heavy and unfortunately a lot do not currently have SSDs i.e. many use older, unnecessarily heavy mechanical drives. The LACIE DJI COPILOT has various features that you might like, and doesn’t require a phone.

The RAVPower FileHub Plus is a versatile wireless travel router, an SD Card USB reader and a portable hard drive companion which includes a 6000 mAh external battery pack. It weighs 5.4oz or 154g, but the majority of that weight lies within the battery. If you’re going to go this route, I’d suggest the RAVPower FileHub Plus, but I’d wait until you’ve read the next method…

A better backup solution for travel photography

Using a smartphone with USB-OTG (on the go) support allows you to plug in external devices and use the phone like a regular computer. While the accumulative weight on a mirrorless camera with a single card slot and a backup solution might be equal to a heavier DSLR with a dual card slot, the weight is modular by design–you can distribute it around your body or bag(s) in a more manageable fashion. Moreover, if you’re using a phone as a backup device, the chances are, you’re going to be bringing your phone anyway i.e. it’s not an additional weight. This solution is your best bet if you don’t own a camera with dual card slots, and even if you do, you might want an additional backup method for a few different reasons e.g. to send an SD card home.

It’s a small, lightweight solution to the problem and as phones get faster, it’ll only get quicker. I recommend picking your memory card reader wisely, for example the Transcend memory card reader is not that good. If you get a Kingston Mobilelite G4 memory card reader, you can plug in an SD card and a microSD card at the same time, and then copy the files from one card to the other. Many do not allow this and only allow you to plug in one card at a time–it is advertised as simultaneous writing. Please read my memory card reader review page for more information. Keep in mind that some phones, including the Samsung Galaxy Note 8, lower the USB port speed if you do this. So you may have to get two card readers if you want to go from SD to SD or SD to MicroSD without using the built in MicroSD card slot.

You can do something similar with a Samsung T5 SSD and you add very little carrying weight (about 30-50 grams.) I’ve bought a SanDisk Extreme Portable SSD.

The caveat with using your smartphone is that write times can be slowish due to the smartphone itself; this depends entirely on the model of smartphone e.g. the Samsung Galaxy Note 8 has extremely fast USB-OTG speeds. Unfortunately, even those that that support USB-C and USB 3.1 file speeds don’t always support USB 3.1 speeds when multiple devices are connected under certain configurations i.e. they revert to USB 2.0 speeds.  Please note, this isn’t as complicated as it sounds. If you have a USB HUB without an HDMI port, you should get the speeds you want.

I recommend the Kingston Mobilelite G4 memory card reader compared to the transcend.

For this phone method to work, you have a few options:

  • Copy files from an external card reader onto an internal microSD card i.e. use the internal microSD card as your backup
  • Copy files from an external card reader onto an internal microSD card and then copy those files back onto an external drive or SD card
  • Copy files from an external dual card reader, from one card to another (the reader must support simultaneous writing and the USB port must support high speed when multiple devices are connected)
  • Copy files from an external card reader onto the phone itself
  • Copy files from an external card reader onto a portable SSD such as the SanDisk Extreme Portable SSD and an Anker USB HUB.

MicroSD cards are improving in speeds but they don’t compare to a portable SSD. Moreover, larger SDs I’ve found are faster even though the ones I have are advertised as 95MB/sec and the MicroSD cards are advertised as 100MB/sec. The Google Pixel, Samsung Galaxy S8 and Samsung Galaxy Note 8 have a USB-C port with USB 3.1 speeds; the Samsung Galaxy Note 8 is superior due to the built in MicroSD card slot.

Many Android phones allow you to connect a Samsung T5 and an SD card at the same time (or connect two SD cards instead of the Samsung T5), and transfer data from one to the other. USB-C USB 3.1 devices (such as the Google Pixel) have changed portable backup tremendously; they allow extremely fast write times and this means that you’ll be able to copy the files on an SD card to an external drive like the Samsung T5 much quicker than before. With most microUSB phones, you can expect write times of about 20MB/sec at best. USB-C is just a connector standard and it is worth making sure the product you are interested in has USB 3.0 or USB 3.1 and not USB 2.0. USB 3.1 technically allows write speeds of 10gb/sec but a phone and SD card often max out at about 90MB/sec (about 500MB/sec with the Samsung T5 or SanDisk Extreme Portable SSD.) That’s about two compressed raw files a second or about one uncompressed raw file in under a second, with the Sony a7rII or Sony a7rIII.

In simple terms, you can expect to backup an entire day’s worth of raw photographs to a 30-50gram external SSD drive or SD card in less than a few minutes. The Samsung Galaxy S9 and Samsung Galaxy Note 8 are the best phones to offer what I want in a backup device but I wish the USB 3.1 port would remain USB 3.1 when a USB HUB is used that has an HDMI port (most USB-C HUBs have HDMI ports). Alternatively, if the MicroSD card slot was a little easier to access, it would help.

Lastly, in regards to this method, be very careful when buying USB-C products. There are a lot of bad USB-C products available i.e. they might have the wrong resistor inside.


An absurd backup method for travel photography

For some people, bringing a tablet with a full sized USB port can be another way to store data; there’s the option to either store data on the tablet directly or use an external drive. For me, this method is absurd as it’s extremely heavy. If you frequently stay in hotels or whatnot and you only go for day hikes, this method might be something you’ll want to consider.

File rotation is slightly better than nothing

The final option, and it goes against my recommendation, is to take a few photographs, take out the SD card (when it is not full) and rotate it with another card. Thereby not losing all the photographs taken in one day.


These are some of the products I recommend. If you own a Samsung phone, get a Google USB C adaptor too.

    Brilliant article. Thanks so much. I’ve gone with the Kingston MobileLite G4 option and there is one little snag for me. My phone is a Samsung Galaxy S9. The phone / card reader would not recognize the SD Card from my Nikon D810 camera. I reformatted the card using the phone, put it back in the camera, took some photos – and it was fine. Copying worked well and was surprisingly fast. BUT, when I formatted the card using my camera, the phone would not recognize it again. I had the same issue with multiple SD cards, so it’s not one faulty card. It is my discipline to reformat the card in the camera each use, after the photos are copied and backed up. It’s generally considered better practice than just deleting the files. If I was in the field for several days and did that out of habit, then took some photos, I would be cooked. No more backups! As long as I stay in the habit of reformatting the card using the phone and NOT the camera, it will be fine. Thanks again.

      Hey, thanks for commenting and I’m glad it’s helped you! It’s bizarre that Nikon’s formatting is doing that. And yeah, you’re right that formatting is or certainly was more reliable (perhaps software has changed now, I don’t really know).

        When using the card/reader with the phone, it automatically creates a bunch of android folders (which don’t have anything in them). It seems if they’re not present the phone won’t recognize the card.

          Ahh that makes sense! Thanks for mentioning it. Sorry for the late reply. I’ve been preoccupied.

    I brought a new device called XferMax X8. XQD/CFast/CF card slot built-in, and no more external card reader required. Fast copying speed reaches about 140MB/s, taking around 20 minutes to backup 128GB data. Two LCD screens allow you to preview photo both in JPG and RAW format. Small and compact, no more computer or laptop when travel around. Same producer with HyperDrive UDMA series products.

      I’ve snipped out the links from your post; you’re affiliated with the company–you didn’t buy it. Please don’t mislead my viewers. The product itself is not faster, it’s heavier and it’s altogether more expensive than the solution I have provided.

    Very informative article.
    I’m an amateur photographer but have encountered the same problem (ie backup while out in the field, without Cloud) and looking for a relatively cheap, reliable, lightweight solution.

    I carry with me a backpack/day pack loaded with required stuff + the camera and lens, so I’m trying to minimize the weight of the backup solution. Preferably the backup will be placed in my pocket, not in my backpack (which might get lost) or left in the hotel.

    I fact, I did more or less what you did.

    I have a Galaxy S8+ with a microSD card + the internal memory, and a Nikon D3300 with a full-sized SD card.

    I purchased a split Y-cable, which has a type-C connector which goes to the phone, a type-A connector to which I connected a fast flash memory stick as target, and another type-A connector in which I inserted the Kingston or the Transcend (with the camera’s SD card as source).
    I then used the phone’s file manager app to copy the daily photos (a few hundred) from the camera’s SD card (and/or from the phone) – to the target flash memory stick.

    The process was incredibly slow and sometimes not all of the photos were copied, so I had to start all over again (after a few minutes the file manager would say that there were some duplicates, so obviously I skipped them).

    The main problem is that I don’t know which component is the bottleneck.

    I then began looking for other alternatives, such as external HDDs (expensive, relatively heavy, not rugged) and external SSDs (expensive, heavy). In most of these cases I’d still need to connect the device to the phone, so I might not see any speed improvement.

    Some of the devices have wireless capabilities, but AFAIK only the WD Wireless Passport has an SD slot, and after reading reviews, I understand that it’s not really a good option. Plus it’s heavy and expensive.

    I also looked for dual type-C and type-A flash memory sticks, so that I could insert the type-C into the phone, the memory card reader into the type-A end – and then use the phone’s file manager to perform the file copying. But I’ve not been able to find a device that is able to use both connectors at once (for example I checked about the Transcend JetFlash 890 USB 3.1 Type-C & USB 3.1 OTG 32GB TS32GJF890S). So no joy here either.

    I found on Amazon several chinese flash memory sticks with an SD card slot, but I did not think they were a reliable solution.

    There are additional alternatives, such as the RAVPower FileHub Plus to which everything could be connected WIFI, but it’s large and relatively heavy due to the included battery (which I don’t need).

    So I still don’t know what to do.

      OK, update.
      I purchased a pair of fast SD cards, used the Kingston Mobilelite G4 and the photo files copy went pretty fast this time.
      Possibly the problem was with the Transcend card reader which was slow (even though it’s USB 3.0) or the USB ports in the y-cable which I used (maybe they aren’t USB 3.0).

      So bottom line, thanks again for the very interesting articles (this one and the one about the memory cards).
      And my technical problem was solved at a very low cost.

        I’m sorry I didn’t reply to your other post sooner. It’s hard to diagnose some of this stuff, and I don’t know if it’s Samsung or android, but the devices seem really fussy. The Kingston Mobilelite G4 is really good yeah. I also recommend getting an “anker” usb hub at some point. I used it a lot while travelling. The adaptors included in the Samsung box are not perfect. I use the google cable. It’s a bit expensive but it’s better. You should try get “solid explorer”, the free version works but I paid for it because it was really cheap :).
