Automated backup of workflows without data

If I understand that correctly, a KNIME workspace contains both the workflows and the data from the workflows.

Is there a way to automatically backup the workflows without data?

While a I work on the workflows there are a lot of changes of course. Backup tools like Time Machine create hourly delta backups and thus store every rerun or change of the workspace data. I removed the KNIME workspace from my Time Machine backup to save space and reduce backup time.

I can of course reset the workflow and copy the files to a new location. Would just be great to hear if anyone managed to automate that process.

I think KNIME Server creates backups but KNIME Teammembers might give you more guidance here.
