I recently bought a 2TB NVME and Argon40 case/hat for my pi. I have everything working well, I upgraded to the NVME in order to use the PI as a file server along with some other self hosted stuff.
I have a habit of experimenting on the pi and messing everything up, I solved this before by having two duplicate 128gb SD cards. The NVME is set up with 3 partitions, nvme0n1p1=512MB MBR, nvme0n1p2 = 100GB root fs, and nvme0np1p3 1.8TB file storage. I thought I would be able to just use SD Copy to write the MBR/RootFS to a 128GB SD card, but SD copy does not let you select partitions, it wants to try to copy the whole NVME to the SD card.
What is the best way to back up my system, so if I screw it up I can easily boot in via USB or SD and copy the working partitions to the NVME?
