FTP server on two as cards?

Projects Programming

Hello I successfully about create a ftp server with no problem on a sd card. The only problem I’m facing which I have no clue how to write to a second sd card to make a copy of the first sd card. Is there a way I can do write to both cards at the same time?

I have both sd cards wired up to spi and there own SS pins. I can see both cards. Just not sure how I can write to the second card a copy of the files of the first card.

I know it will take time like all things and that is okay. I just want to see a copy of it just in case.

For some tasks a raspberry Pi makes it much easier to realise a complex task.

Or you use two extra microcontrollers
Your master-µC uses two serial connections and each SD-µC has one SD-card.
Depening on how much data you want to story you could use two I2C-FRAM-chips.
For bigger files a raspberry Pi is the way to go.

hello Everyone thank you for the update and replys. A lot of this is helping me to understand. From what I'm reading is to two dual Sd cards I would need let one sd card finish before the second one uplaods files to it. I don't know if this is correct or not. But it seems to be that having a single sd card is the way to do. I will have to rethink what I would need to really do. Being limited on the arduino. I will post an update. What I have found out or choosen to do in a couple of days.
