I have a Raspberry Pi 4b with the latest Buster Desktop running some weather station software on a 400GB SD.
I have used sudo raspi-config and set it to boot from a USB disk if present.
I want to transfer the image from the SD card to a USB Disk and do away with the SD Card
Normally I would shut the Pi down and use Apple Pi Baker to clone the SD card and then write the image to the USB Disk.
This will take some time and leave some weather data missing.
If I used the SD Card Copies app found under Accessories in the Desktop Menu can this copy the live SD to the USB Disk?
