+Your First Day at Work
+======================
+
+**Senior**
+
+  Welcome to ACME Inc.  This is your first day here, right?
+
+**Junior**
+
+  Hi! I am excited to start working.  What will be my first task?
+
+**Senior**
+
+  First let me explain to you what is our infrastructure.
+
+**Junior**
+
+  Ok.
+
+**Senior**
+
+  We have two Linux machines that provide services to our employees.
+
+  1. The Corporate Server:  Provides email, database and web services.
+
+  2. The Backup Server:  It is used to store backup of the important
+     company data. 
+
+**Junior**
+
+  That's it? Ok, just like Google.
+
+**Senior**
+
+  Well, I think is time for you to start with your first task.  It just
+  so happens that we received another request to backup the database
+  from the projects team.

+Backup that Database!
+=====================
+
+**Junior**
+
+  A Backup? Don't you have this kind of things already automated?
+
+**Senior**
+
+  Well, is not that simple. We of course have periodic backups. But, our
+  project team ask us for a backup every time a project is finished.
+
+  I've already prepared a script to do the task. Before executing it in
+  production download it and test it in your own machine.
+
+  .. todo::
+
+     - Link backup script from Github.
+
+**Junior**
+
+  Ok, done! When I executed it the output says:
+
+  .. code-block:: console
+
+     $ ./backup_db.sh
+     Backup done!
+     Your log file is at /tmp/backup_db.log
+
+**Senior**
+
+  That's right. That script performed the backup and stored it into the
+  **Backup Server** and appended some information into the backup log
+  file at ``/tmp/backup_db.log``.
+
+  Now you can SSH into the **Corporate Server** and make the real
+  backup.
+
+
+**Junior**
+
+  Wait, wait... how long have you been doing this?
+
+
+**Senior**
+
+  This procedure was already here when I arrived.
+
+**Junior**
+
+  And why don't they do it themselves?  I mean, what do you contribute
+  to the process?
+
+**Senior**
+
+  I am the only allowed to SSH into the **Corporate Server** for obvious
+  reasons.
+
+**Junior**
+
+  Why do you need to SSH in the first place? Couldn't it be done
+  without SSH?
+
+**Senior**
+
+  Actually it could be done with a promising new tool I've just found...
+  Kapow!
+
+  Is a tool that allows you to publish scripts as HTTP services.  If we
+  use it here we can give them the ability to do the backup whenever
+  they want.
+
+**Junior**
+
+  Sounds like less work for me.  I like it. 
+
+**Senior**
+
+  Ok then, let's try on your laptop first.
+
+  First of all you have to follow the installation instructions XXX.
