Hello i been looking and researching for my later on project I'm soon to work on that needs SD cards I was wondering If it is really possible to have 2 SD cards with the Same information and files on it. So if one fails at least i will have a backup copy. Kind of like a PC Raid mirroring of some kind. Also be able if i delete one file from the master SD card that the backup card same file can get deleted as well.
I have searched forms on here and in google about paralleling them. But found there can cause some major problems. Also about setting the SC Slave select pin for each SD card module sense they use the Same SPI channel and how that might cause a little problem. But not really found a way how to make it redundant. I was wondering if anyone has gotten this to work in this way and what Steps would i need to take to make this work?
Thank you.
