    I have no idea what that app does, but copying live filesystems is tricky.

    I'd think about downloading a fresh image and writing it via dd to the USB stick. Then use rsync to mirror your running system to the USB. That way
    you get a known-bootable partition structure on the USB followed by the file updates from your running copy. The only thing it might not copy is files
    that were being written at the time of the rsync.

    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.

    Yes
    I have done so on a number of systems
    It is designed for exactly this purpose

    BTDT several times.

    It depends ... as always.
    The system needs to be pretty quiet (*), nothing really doing any work.
    Then a "dd" followed by an "fsck" on the destination usually gives the
    desired result.

    (*) Of course, doing this on a busy web server may not work
