For Ubuntu, to make image of card:

Code: Select all

cd ~
sudo dd bs=1M if=/dev/sdb of=my_os.img
Then, to copy to other cards:

Code: Select all

sudo dd bs=1M if=my_os.img of=/dev/sdb
Be very careful with the /dev/sdb - this must be the path of your SD card reader (use dmesg to check after plugging in the card).

Also make sure destination card is big enough to receive the image otherwise you'll have problems. There is a tool called (I think) PiShrink that will make the image file smaller, giving a better chance of it fitting on other cards.

Or is this still too much human intervention?

Yes the tool to remove the unused portion of the image is PiShrink and it works very well. PiShrink even sets up the card to run the file system expansion command on first boot to make the all the space on card usable on the new Pi like a fresh Raspbian install does.

If you are using Raspbian on your Pi, you can use the SD copy utility to make a backup of the OS on a new SD card in a USB card reader. This tool will resize the OS copy to fit the new SD card as long as that card can hold the copied image with the free space removed. If the SD card is larger than the source SD card the copy will be expanded to use the entire card.
