Downloading data from the datastore

Question

I wanted to download the data on my online app's datastore, I followed the guide on code.google, I added this to my app.yaml file

builtins:
- remote_api: on

But when I updated using appcfg.py update src and called this:

appcfg.py download_data --application=myapp --url=http://myapp.appspot.com/remote_api_path --filename=first-test-backup`

I got an Authentication error, pretty much the same case mentioned here, so I tried putting this:

- url: /remote_api 
  script: $PYTHON_LIB/google/appengine/ext/remote_api/handler.py 
  login: admin 

before any catch-all handlers, but then got this error: threadsafe cannot be enabled with CGI handler when I tried to update, so according to this discussion, I replaced it by:

    - url: /remote_api 
  script: google.appengine.ext.remote_api.handler.application 
  login: admin 

Which gave me again the authentication error, I also tried adding ('/remote_api', google.appengine.ext.remote_api.handler) to app = webapp2.WSGIApplication, however still the authentication error persists.

I use a High Replication datastore, but according to code.google the only drawback is that I might not get the latest data.

How can I download my data?

Try this:

builtins:
- remote_api: on

And for url

appcfg.py download_data --application=~myapp --url=http://myapp.appspot.com/_ah/remote_api --filename=first-test-backup

Atttention _ah in url: http://myapp.appspot.com/_ah/remote_api
