To store a large folder into a single file without compression and with a progress bar, one can use the following one-line command:
tar -cf - ./Downloads/ | (pv -p --timer --rate --bytes > backup.tar)
The command will keep the original folder intact.
Requirements:
sudo apt-get install -y pv
Demo (in my case, my folder is ./Downloads/ and my output file is adb_int.tar):
Credits: the command combines user86969's answer with Jakuje's answer.
