The company I work for used to be hosted on 3dcart. One day the site went down and their support couldn't tell us why. After over 24 hours of downtime they restored service but left 5 days of all records and customizations across the entire store, from the DB to the damn templates. Their support apologized for the outage blaming the disaster on a combination of hard disk failure and a bad update to their backup script. They were not willing to assist us in any way. We were forced to manually enter 5 days of orders (which gave them new order numbers and caused more problems), products and template changes, with order data coming from an internal email which was luckily CC'd on the order confirmation email. Thank God for whoever setup that CC, it saved our asses. In the end it cost our company thousands of dollars and 3dcart never composited us in any way.
