I am new at ubuntu and dealing with servers. I use Ubuntu 16.04 x64. I want to have a backup for my entire system, So I followed this video https://www.youtube.com/watch?v=KTayZIou-1M
I type this command
sudo tar -cvpzf mybackup.tar.gz --exclude=/backup/mybackup.tar.gz --one-file-system
But I got this error
tar: Cowardly refusing to create an empty archive
Then I realised that I forget to add '/' after '--one-file-system' So I add it.
sudo tar -cvpzf mybackup.tar.gz --exclude=/backup/mybackup.tar.gz --one-file-system/
and get this error
tar: unrecognized option '--one-file-system/'
Thanks in advance.
