That's correct. Ever since HostingDiscussion moved to Hands-on for the web server backups have been a crucial part to how things are operating. We've always had the hourly, daily, weekly and monthly backups, but we've now added in backups every 30 minutes, and storing those for 48 hours (on top of the normal backups).

The more backups to choose from, the better/safer things are here at HD. The extra backups in the 30 minute block produces no significant load on the server which is why it was implemented.
