Any precautions Rebuilding EasyApache Configuration?

I'm new to WHM and CPanel and would like some feedback on rebuilding and restarting Apache. I have a server running several websites and would like to turn off directory listings globally. Usually I'd edit the httpd.conf and restart Apache. Looking at the Apache conf and reading the WHM/CPanel documentation the httpd.conf is automatically generated, and the most sensible way to do this would be via the WHM portal and have it rebuild the conf files and restart Apache for me. The options I'm looking at are under Home " Service Configuration " Apache Configuration "Global Configuration and the UI reports "For your changes to take effect, the Apache configuration must be rebuilt and Apache restarted." Are there any known gotchas with the process? should I be concerned Apache may not restart or that direct modifications to httpd.conf (unknown to me) could be lost or messed up? I've backed up /usr/local/apache/httpd.conf. Presumably I could replace the newly generated httpd.conf with the backup and restart Apache from the command line if things go awry? I guess I'm asking what backups need to be taken and how do I recover if it all goes wrong?
