I am able to download a backup of my production GAE data-store but I am not able to upload the backup to my dev app. Here are my attempts:
Downloading store from production, works as expected:
appcfg.py download_data --application=s~myApp --url=http://myApp.appspot.com/_ah/remote_api --filename=backup1
Upoading backup to dev store, fails:
appcfg.py upload_data --application=dev~myApp --url=http://localhost:8080/_ah/remote_api --filename=backup1
Uploading data records.

It seems error 61 is a port error. The app is running, I've signed in as admin via the browser and I've also put in my email/password as part of the CLI command. Some records always get uploaded and then the upload process gets cut off.
I have always found uploading data to the local data store more reliable setting the number of threads to 1. Rememeber the dev server is essentially single threaded. Try running it with --num_threads=1.
I would also recommend setting --db_filename=DB_FILENAME to create a progress db, which means you can restart from where it got to if it fails.
I have also at times had to reduce the batch size when trying to write large entities.
