Since v8.05, Syncovery natively supports Google Cloud Storage. You can choose it in the protocol selection on the Internet dialog.
The native Google Cloud Storage API is highly recommended and more efficient than using the older XML (S3) API described below.
You can still use the Amazon S3 compatible API for Google Cloud Storage. In that case, choose S3 as protocol, and specify your bucket like this:
bucketname@storage.googleapis.com
You can get your Access ID and Secret Key via the Interoperability tab sheet of the Cloud Storage Settings page
https://console.cloud.google.com/storage/settings
Please don’t choose unsupported features like Reduced Redundancy, as they will cause errors.
