SD Card Copier(piclone) is an utility to back up Raspberry Pi to an SD card reader.
This is an application which allows the SD card inserted into the Raspberry Pi to be copied to one in a connected USB reader.
To back up your existing Raspberry Pi OS installation, put a blank SD card in your USB card writer and plug it into your Pi, and then launch SD Card Copier. In the ‘Copy From Device’ box, select the internal SD Card.

In Ubuntu, you can build piclone by following the steps below:
git clone https://github.com/raspberrypi-ui/piclone.git cd piclone ./autogen.sh ./configure make sudo make install
To run the application with terminal,
sudo dbus-launch piclone
