You may be facing the same following error while you were restarting/reloadig the Apache server on Ubuntu. tanvir@tanvir-laptop:~$ sudo /etc/init.d/apache2 reload  * Reloading web server config apache2  apache2: Could not reliably determine the server's fully qualified domain name, using 127.0.1.1 for ServerName To fix that problem, you need to edit the httpd.conf file.

Suppose you have a directory called source, and you want to back it up into the directory destination. To accomplish that, you'd use: rsync -a source/ destination/ This command is equivalent to: cp -a source/. destination/ except that it's much more efficient if there are only a few differences. Just to whet your appetite, here's a way to do the same thing as in the example above, but with destination on a remote machine, over a secure shell: rsync -v -e ssh source/ username@remotemachine.com:/path/to/destination/ Note: -v, --verbose     Display the names of files transferred and statistics related to the transfer. -e shell     Use shell (which can be a complete command with arguments, enclosed in quotes) to create the connection between two systems for file transfer.
