    From your live stick, bevor install, do

    # cp /dev/your-disk /your/image.img

    or to save space:

    # gzip < /dev/your-disk > /your/image.img.gz

    or faster but might need to install it first:

    # lz4 /dev/your-disk /your/image.img.lz4

    To get a list of your disks, there’s lsblk.

    I recommend partition-wise backup, it’s always a bother to extract/shrink individual partitions in images of whole disks. That would be /dev/your-disk1 etc
