Prestashop "guarantees" a backup, but I opened I ticket, did everything they asked and was promptly ignored. After spending a month working on setting up my store, I got busy around the holidays with work and family and didn't log in for 30 days and the DELETED THE ENTIRE STORE without any warning whatsoever. This sucks. I'm going to give them another week and then move on to something else, perhaps Magento or Shopify.
