To utilize copying to a cloud in ShotPut Studio you must first connect with your chosen cloud provider. It should be noted that currently a cloud can only be used as a destination and is not supported as a source.
To establish a connection to your chosen cloud provider, first click the Gear Icon to the left of the S3 category header.
After doing so, a pop-up will appear. Once adding a provider, you can manage it in this pop-up. However, if you have not established any connections or would like to establish a new connection, click the + icon in the S3 Connections view and then select your provider.
After this, click the Edit button to add the necessary credentials and enter your Application Key and Application Key ID (ShotPut Studio will ask permission to access your Keychain when you save your credentials the first time. Select Always Allow.).
The connection status will then update automatically provided the details were entered correctly. Your available buckets will then populate underneath the corresponding provider icon. After this, you can begin copying to the S3 bucket(s) or subfolders by dragging them into the central queue of the Copy tool or by adding them as a destination in a Copy Preset.
