I'm fortunate. My Nikon D300s has two cards. I put RAW files on one which of course I can extract jpegs and the other the highest quality jpegs so if one card fails I should as least have a good image. I too don't use large capacity cards either for the reason given above.

Showing off with a Nikon Dave, us poor Canon users don't have that priviledge, I used to though with my Olympus (Compact Flash and XD)

Handy feature to have on top end cameras. Both my Canon and Fuji have single SD Card slots, I bought a WiFi SD card hub so I could copy images onto my Android tablet while on a road trip. I use box.com to backup my images, although not as regularly as I should be.

I have a 64GB card in my camera so plenty of space 🙂

I NEVER have more than a 16GB card in my camera, I always have 5 or 6 cards handy, as a pro photographer I know only too well that cards can fail at any time, the thought of loosing 64GB of images in one go should one fail mortifies me.

Lol - no would never lose that much data. Once a shoot is done, all the photos are imported into Lightroom and are stored on my PC backed up to an NAS device. The SD card is then re-formatted for the next shoot. I do also have a spare 32gb card just in case though  🙂

I love the Nikon feature of two memory cards.  We have it set to copy all photos to both cards and then use the SD card for all the transfers and the compact flash purely as back-up.

Thus far, in probably 5 or 6 years, and many thousands of photos, we've never needed the back-up, but it's there as insurance.

I've only had one SD Card fail, and that was the first one I bought for a new camera so luckily didn't lose anything important.

I would recommend a cloud storage backup to ensure you have off site backups. I know 2 people who lost everything to a house a fire and burglary, they even stole the backup drive he had hidden in the laundry basket.
