I am trying to make a backup of two directories, /etc/httpd and /etc/letsencrypt
I am using the command
tar Pcfvg httpd_backup.tar /etc/httpd/ /etc/letsencrypt/ >/dev/null
The redirect to /dev/null at the end was only added for debugging purposes.
I get error
tar: /etc/letsencrypt/live/example.com: Directory is new
What does this error mean and how do I backup the directories successfully?
