To run a dataset export, you must first create export settings (see https://support.lityxiq.com/002683-Export-a-Dataset---Settings)
Then, you have the option of executing the export manually, or scheduling it (including automating the export process).
Executing a Dataset Export Manually
Select the dataset from the list of available datasets, click the Selected Datasets menu button, click Export, then click Export Now.
You will be asked to confirm that you want to export the dataset. You can then open the Console to track progress.
Scheduling a Dataset Export
To setup the dataset to be export on a schedule, select Schedule It from the Export submenu.
This will open the standard LityxIQ scheduling dialog. See https://support.lityxiq.com/882325-Using-the-Scheduling-Dialog for help.
In particular, the export can be automated by selecting Upon Data Refresh as the export schedule. This will export the dataset, based on the export settings, automatically anytime the dataset is changed.
