Matt, eez.io is a hosted ecommerce solution, and you don't need to make any backups as we perform all needed backups on our end. We generate backup of all stores (both database and files) on daily basis and our tech team is standing by to resolve any issues that may arise. At eez.io we prefer to take care of the tech aspect so that you will be able to concentrate on ecommerce part of your business.
In any case, if for some reason you still prefer to store a backup of your store database and files, please contact us directly and we will be happy to send them to you.
