Creating partial backup image of the SD card ?

[Pegoncology]

Hello. I have a full 128go Recalbox on a pi 3 linked to my TV.
I'd like to have a second one on 16go MicroSD on a portable device with a pi zero.
I'd like to transfer my favorites system to the 16Go one. I don't have a connexion with the pi zero (no wifi nor lan).
I suppose I have 2 solutions :

1. Using a usb wifi dongle and manually transfering the roms and scrape folders from 128Go to PC and then from PC to 16Go

2. Creating an image of the 128Go bit it needs to be partial. Is it possible ?

Or maybe I have to delete manually the folders I don't need before making the image which suits the 16Go ? (and obviously making a copy of those folders to put them again in their place after having done my image)

Another question : will the 128Go image from Pi 3 work on a Pi Zero ?

Thanks for helping

@pegoncology Hi !

Let's put it shortly : you can't achieve what you want to do the way you're trying to do it. Let me explain :

• you can't use network on your pi0
• you can't make a partial backup

Pi3 and Pi0 are different architectures, therefore they are not compatible. You can't plug one SD to the other pi.

For whichever purpose, you'd need linux to copy anything on the pi0 sd card.

The only "easy" (ahem ... that is quite a relative meaning ...) would be to use a USB key + a USB hub on your Pi0 (because I guess your pad is a USB one ?). Recalbox can mount a USB key quite easily (check our youtube channel, the tutorial playlist).
