Startup Idea : Wordpress Backup Service

There more than 50 million Wordpress user out there and many of them are using self-hosted solution. If you use Wordpress yourself you would've known that the tedious part of using it is when it comes to backup. Wordpress backup consist of 4 basic part -Database -Content(post/page) -Uploads folder(theme/plugin) -Wordpress config file There already many Wordpress backup plugin and solution such as BackWpUp, CodeGuard and Vaultpress but they didn't cover all 4 basic part and backup plugin failed most of the time. Also most premium solution start really steep price, take note that most Wordpress user are on <$20/month hosting yet most existing backup solution start at $15! I'm thinking of manual Wordpress backup service where actual human do the backup(to minimize error) with low starting price($3 weekly backup/$9 daily backup). Business value is good only if the workforce come from developing or under developed nation. See details here : http://mdnor.tumblr.com/post/32543372771/startup-idea-wpzenbackup
