@Perfect-Web, sorry for that, but you need to do new clear installation. Looks like that your version is old. In 1.0.0-beta release all data/schema upgrades were removed and all changes from them applied in data/schema install scripts. It means that it is not possible to do system upgrade to 1.0.0-beta from all previous versions.

and how do i backup the data ?

Try this: http://devdocs.magento.com/guides/v2.0/install-gde/install/cli/install-cli-backup.html

Depending on your Magento build, the command might not be available.

I think you come across this when you have a newer version of the components installed, example latest from development branch, and then you checkout a released version. I'm experiencing this now. The solutions isn't to upgrade but to uninstall and re-install, which has other implications. The database has to be regenerated.
