Scheduled Backups for Free!

I have used this free version to restore a website in the past and it worked. I have it installed on several non-money-making sites, including my most recent project, a non-profit site that includes a calendar/event registration system. Since it is a dynamic site, it is very important that it gets backed up nightly. I love that the backups happen automatically without me having to think about it, and I get an email the next morning telling me it worked. I set the automatic backups to be sent to my Dropbox account.
