Louis has a Wordpress blog and wants to know what the best option is for backing it up. Leo says that if his ISP or blog service doesn't offer a backup, then he's on his own. There are Wordpress plugins that do this and Leo uses them as a second line of defense. It essentially backs up the Blog database and customization. It would let him know by email when it backs up and when it fails.
One option is Backup Buddy by iThemes, which is $80 a year for two sites. That's what Leo uses. Another is Akeeba, which is free. There's also a Backup Wordpress to DropBox plugin. Check out these alternatives to Backup Buddy.
