Yes, you can configure a recurring export to an external destination via FTP or SFTP protocol. This option is available in the export profiles.
Here is how to proceed:
Go to the Data Flow menu and click on Scheduled Exports.
If you already have one, click on the edit button for your scheduled export.
If you do not have any, click on the New scheduled export button.
After filling in the other settings, scroll through the list of available protocols and choose the one that suits you.
Once all fields have been filled in, click Create if this is a new scheduled export, or Save if this is a modification to an existing scheduled export.
