Public bug reported:
When duplicity is used to back up to Google Drive with the gdocs:// URL
scheme and --asynchronous-upload, duplicity reports that the backups
were uploaded correctly even with the internet connection disconnected.
The gdocs backend should instead report back, telling duplicity that the
upload has failed and stopping the backup as this can lead to incomplete
backup chains when the internet connection is later reconnected.
