How to Make Your Ubuntu System Mirror?

Hello, everyone, I want to make my own system image, because the software package and dependencies are installed, and it is difficult to reconfigure on other systems. Now the image can be used, but there is a problem. This image is based on 32G SD card, and can only be replaced by 128G card. With 32G, is there any way to solve this problem?

I am assuming you are talking about and SD Card used for a jetson nano? please check out this thread:
