If you are a pro, do you use two card slots for backup? Locked

I don't want to start the debate if the EOS R is a pro body or not. I'm fine declaring that it is not. But one of the nits against it is it has only one card slot and "no pro would ever use it" is stated emphatically very often. So, I'm curious.

I'm an avid amateur that might make a few dollars here and there on my photography and I have a nice job to pay for my toys. The few professional photographers I've known tended to be on an extremely tight budget and had consumer grade bodies that were a few years old. I've also got this hint from some YouTube videos.

I'm curious if you use a body with dual card slots and you have it set up to copy each image to both cards.

I think if I was really worried, I would cycle through a lot of small cards and, if I could afford it, have a pocket PC that could backup the cards as they got full to safer storage rather than trusting the camera to do the backup. The camera doing the backup still has a single point of failure and a firmware glitch in the camera seems more likely than today's cards having the glitch. To rephrase, it seems like both copies the camera is making are going to get damaged more often than just one copy.

I have been shooting professionally since 2003 using mostly Canon 1 series bodies that has 2 slots. I have never used the 2 slots as backup, mostly just one card and if I need the extra capacity 2 cards but not as backup.

In all that time and lots of photos (around 1.7 million "keepers" in my collection) I have never had card corruption or lost a single image! I believe this whole storm about the lack of a second slot on the R is just random noise......

Sorry but your explanation makes no sense.

Here's an application of your logic:

1. I've been smoking cigs for 60 years and I never got lung cancer, so why should I quit?
2. I've never been in a car accident in 40 years of driving, so why do I need car insurance?
3. I've never had a drive crash on my PC, so why do I need a back up?
4. My DSLR card has never got corrupted so why do I need to use slot?
5. My dad worked the coal mines for 40 years and he provided ok, so why do I need to get a college degree?

You obviously are not a true professional.
