I am a new user of Magento.
I want to backup and restore function.
When I try one of these three (system backup, Database and Media Backup, Database Backup), I get "You need more permissions to create a backup.".
So please guide me which folder and database permission to configure.
Actually to take the backup and to use magento 's backup and restore functionality - you must have writable permission for the user which you are using to take a backup !
so here , you are facing error because you don't have writable permission - so give writable permission to user and then try it for the same !
Fore more reference refer this link - https://devdocs.magento.com/guides/v2.0/install-gde/install/cli/install-cli-backup.html
Hope it helps !
