after days of searching, I have concluded that the right question would be better. I am working on app backend. I need it to backup some files regularly on Google Drive. Do I understand it correctly that I need Google For Work account so I can use Server2Server?
According to this https://developers.google.com/api-client-library/php/auth/service-accounts Google wants me to grant access only via Google For Work account. Have I missed anything if I just want my web based php script executed by cron to backup few files on Google Drive? Is there any other option?
Thank you!
