Almost definitely because the (effective) user running mythbackend 
doesn't have access to the /root/ directory structure--i.e. you're not 
running mythbackend as root (which is a good thing since doing so isn't 
required, and should really never be done).  Note that root may start 
mythbackend (which I'm guessing is the case since HOME is set to /root), 
but may specify a --user argument to drop privileges or may start the 
process as a different user with sudo or su or ksu or whatever.

That are due to the fact that it doesn't have information about how to 
connect to MySQL.

So, move your config.xml file to a location where the user running 
mythbackend can access it, and ensure the HOME environment variable is 
set appropriately.  (So, for example, put the config.xml in 
/home/mythtv/.mythtv and set HOME to /home/mythtv before starting 
mythbackend.)
