/**
* Backup system
*
* This function is used to backup the system. There are 2 types of backup, database only and full.
* In the first case (the default), only the database is backed up, while in the second case, files
* are backed up as well.
* <br/>Example:
* <code>
* $backupFile = EfrontSystem :: backup('13_3_2007'); //Backup database only
* </code>
*
* @param string $backupName The name of the backup
* @param int $backupType Can be either 0 or 1, where 0 siginifies database only backup and 1 is for including backup files as well
* @return EfrontFile The compressed file of the backup
* @since 3.5.0
* @access public
* @static
