I had the same problem and just got it to work. As the OP mentioned, I could not manage to get it to work following the steps suggested by the appcfg.py error message (*oauth2client.client.ApplicationDefaultCredentialsError: The Application Default Credentials are not available. They are available if running in Google Compute Engine. Otherwise, the environment variable GOOGLE_APPLICATION_CREDENTIALS must be defined pointing to a file defining the credentials. See https://developers.google.com/accounts/docs/application-default-credentials <https://developers.google.com/accounts/docs/application-default-credentials> for more information.*)
Getting the key by those instructions did not work (I tried the app engine key when prompted to select whether I wanted compute engine or app engine key, maybe I chose wrong). I wrote the solution up as a blogspot with the relevant screenshot here: Backing up data from App Engine with appcfg.py <http://www.bemmu.com/how-to-backup-data-from-app-engine> Anyway, steps I followed to get it to work: 1. Go to IAM <https://console.cloud.google.com/iam-admin> 2. Click the three balls on the right side of "Compute Engine default service account" 3. "Create key" 4. JSON 5. Save the key compute-key.json Then create a script called "backup": GOOGLE_APPLICATION_CREDENTIALS=compute-key.json appcfg.py download_data . --filename=data_store_backup Instead of . you can also put the full path to the directory containing app.yaml if running from somewhere else. If you run into "HTTPError: HTTP Error 404: Not Found" when doing download_data, your appcfg.py is so old that is hitting a deprecated endpoint. Update your appcfg.py and try again.
