which sd card back-up solution in the field ?

Well...... as they say in english .... 'there are many ways of skinning a cat'

ask the forum and you will get multiple solutions ranging from the blase to the multicopy security obsessed neurotics .....

These days I have SD1=SD2 so I always have 2 copies. When full, cards are stored in 2 separate locations (bag and pocket).

If I'm away from home, after I'm done at that location (and often on the way back in the car) I'll download the new images to my iPad Pro. That night I'll usually process the best using LR mobile and Photoshop fix. These images are automatically synced with LR via the cloud to my home computer, so at least the good ones are ok whatever happens. The iPad functions as my back up in the unlikely event that both SD cards go astray. I wipe the originals on the iPad when the images are transferred to my home computer (with 3 rotating external back-up drives). 

I have 4 pairs of 16Gb cards for my SL and only reformat the oldest pair when the others are full, so they often remain as a secondary back-up for months. 

One external HD is in the garage, one in a safe in the house and one attached the computer, rotated every week or earlier if I have something really important 

Tony Northrup did a video about card failure a while back which is interesting .....

Interested in the IPad Pro idea. Do you take raw or JPEG on the SL, or both?

I keep the originals on the SD card and just make sure I have more than enough cards for the trip

The files are backed up onto a Hyperdrive Colorspace UDMA3

The screen is by no means up to the quality of an iPod or iPhone but 'adequate' for it's intended purpose.

The cards and Hyperdrive are the kept in separate bags (backpack and luggage or split between my wife's and my luggage if we're travelling together)

I just back my images up to Lightroom on my phone via an SD card reader, though I do tend to edit as I go to keep numbers down. This has the handy side effect on my images being on my computer already when I get home.

the iPad pro takes the DNG's off the card .... even if both JPG and DNG are present (or at least there is only one version and it doesn't seem to give you a choice). Viewing them in camera roll shows only the embedded jpg ..... but LR mobile shows them as DNG's and views them at full res once the image is loaded. Processing options are surprisingly sophisticated and actually easier and more accurate than LR as you can do it all on the touchscreen with a finger ...... or even more accurately with the Apple Pencil. You can export to Photoshop Fix to clone out stuff .... which uses what looks like the same content aware algorithm as in the full PS version as it is absolutely brilliant, and it saves it back as DNG (not PSD) which is handy. I've just reviewed the images I processed on the iPad last week when away, and to be honest I doubt I could improve on them much re-doing them in the full version of LR and PS on my iMac.

I use the Western Digital My Passport Wireless HD as well. You can access it by Ipad and so controll the copies. But sofar, I’ve never seen any error.

I would be quite reluctant to use the Ipad pro itself as backup medium. I have always the feeling that files are coming out differently comparing to the original.
