I want to make client version of GAE app that store exact data of online version.(myapp.appspot.com) If i can use sdk instead, is any library or tools to sync online and sdk version? I try using bulkloader but i can't load downloaded data to local SDK? Please help.
As explained in this article (link updated, thanks to Zied Hamdi)
You simply need to enable the remote api
builtins:
- remote_api: on
Update your application then run the following commands:
appcfg.py download_data -A s~YOUR_APP_NAME --url=http://YOUR_APP_NAME.appspot.com/_ah/remote_api/ --filename=data.csv
appcfg.py --url=http://localhost:8080/_ah/remote_api/ --filename=data.csv upload_data .
Edit for After April 12th 2016 on Latest AppEngine SDK:
The above works for SDK version 1.9.0 and before. However with the depreciation of ClientLogin, the above will cause an error of
03:13 PM Uploading data records.

Recommended by Anssi here, we can use the API server directly without running into this error. For a typical dev_appserver startup you get the following output
INFO 2016-09-09 19:27:11,662 sdk_update_checker.py:229] Checking for updates to the SDK.
INFO 2016-09-09 19:27:11,899 api_server.py:205] Starting API server at: http://localhost:52497

INFO 2016-09-09 19:27:11,918 admin_server.py:116] Starting admin server at: http://localhost:8000
instead of the above for upload use the API port, in this case
appcfg.py --url=http://localhost:52497/_ah/remote_api/ --filename=data.csv upload_data .
