Howdy!<p>I'm in way over my head on this project!<p>I've got ~500 Wordpress sites I'm managing and I need a reliable way to backup sites. This would be for both security and development purposes.<p>I know there's a lot of redundant files across sites, so I think I should approach it in two ways. I should have a system to backup the MySQL databases and then another way to backup critical files from /wp-content and other folders.<p>As I mentioned before, I'm in way over my head with this! I'd greatly appreciate any tips or advice.<p>Cheers!
