How long does Linux and Unix already exist?
And NO BACKUP PROGRAM to a plugged-in USB drive available ?!?

sudo tar --exclude=/media/* --exclude=/proc --exclude=/dev --exclude=/tmp --exclude=/run cvzf /media/pi/usb120drv/pibackup.tar.gz /

neverless there is this error:

pi@raspberrypi:~ $ sudo tar --exclude=/media/* --exclude=/proc --exclude=/dev --exclude=/tmp --exclude=/run cvzf /media/pi/usb120drv/pibackup.tar.gz /
tar: Eine der Optionen „-Acdtrux“, „--delete“ oder „--test-label“ ist notwendig.
„tar --help“ oder „tar --usage“ gibt weitere Informationen.

...?

ps,
I'm a complete beginner and my English is very poor, especially I don't understand sort of slang like dd'ing :-/
rsync appears extremely complicated, except there is 1 single install programm for the whole installation (like setup.exe for windows programs)
and just 1 command to start (like double-click on sort of "rsync.exe"
and adjust the settings (like target drive) interactively.

tar  cvzf /media/pi/usb120drv/pibackup.tar.gz / --exclude=/media/* --exclude=/proc --exclude=/dev --exclude=/tmp --exclude=/run

nevertheless, the USB drive is plugged in and can be accessed via the file explorer

cd /media/pi/usb120drv/
sudo tar cvzf ./pibackup.tar.gz / --exclude=/media/* --exclude=/proc --exclude=/dev --exclude=/tmp --exclude=/run

We actually thought of selling this to the Soviets to set their computer science
progress back 20 or more years.
