Cyberduck Help / Howto / Google Storage

Google Storage for Developers is a S3 compatible service currently in development and open by invitation only. Support must be enabled first using a hidden configuration option using defaults write ch.sudo.cyberduck protocol.gstorage.tls.enable true using the latest snapshot build.

Refer also to S3 in general.
