Use

• Full local backup:

  $ sudo rsync -aAXv --exclude={"/dev/*","/proc/*","/sys/*","/tmp/*","/run/*","/mnt/*","/media/*","/lost+found"} / /path/to/backup/folder --delete --info=progress2
  

• Full remote backup:

  $ sudo rsync -aAXv --exclude={"/dev/*","/proc/*","/sys/*","/tmp/*","/run/*","/mnt/*","/media/*","/lost+found"} -e ssh / user@123.123.123.123:/path/to/backup/folder --delete --info=progress2
  

Tip

Make sure that the target folder, on the remote system, is owned by "user". If "user" is root, make sure to permit root login on the remote system:

# vi /etc/ssh/sshd_config
    > ...
    > PermitRootLogin yes
    > ...
# systemctl restart sshd
