Description of my issue:
We can use [HOST] [DATE] [TIME] as part of the backup names but it would complete the circle if it was prepended with [SITE] which used the site name from the global configuration.
Here's the code you would use
$config = JFactory::getConfig(); str_replace(' ', '', $config->get( 'sitename' ););
It would help me a lot, I assume it would help others. I guess you would need to do a check to remove spaces from the sitename.
