For test operation the redirection can be activated. All uploads are then redirected to a specified server.

There are two different options for FTP upload:

Upload immediately

The file is uploaded immediately. If the upload is triggered by a user (e.g. by a state change that triggers an upload), the user must wait until this operation is complete before they can continue working. If an error occurs during the upload, the entire action (e.g. state change) of the user is rolled back.

Upload via queue

The file to be uploaded is first stored in the FTP upload log as a not-yet-uploaded file and is only sent by a regularly running job (Administration > Job control > FTP upload). This must of course be activated. As a result, the user is not held up unnecessarily long during their work, and a faulty upload does not cause their action to be aborted.
