Absolutely, I have a least three cameras with me, several lenses and backup lenses, several flashes and more batteries and memory cards than will ever be needed.
All of my cameras save the images on two memory cards simultaneously during the day.
My first job when I arrive home, before even getting changed, is to backup the images to two different external hard drives and then a further copy is securely backed up to my cloud backup service overnight.
I take the storage and security of your images very seriously.
