Does Printer Bridge offer a site backup?
Printer Bridge does have a pricing backup but from a data recovery level. Meaning if a hard drive crashes we will be able to recover the data. But there is no history system in place for pricing. We do however store a history for the content added to the CMS pages. We work on enhancing the platform and will definitely look into implementing a history system for pricing.
That being said, it's always recommended that you keep a hard file copy/backup of your pricing offline. Suggested to have an excel file with all your price/markup breakdowns.
Regarding the "Auto set Prices" button, you are given prompts before taking action on resetting prices. You actually get three prompts. Please see a screenshot of one prompt below.
