How to backup data file?

[K1200]

My application uses the simple separation model: GUI.fp7 + data.fp7

I'm trying to implement a scripted backup, but the file that is written out is the GUI -- and NOT THE DATA.

Script step used: Save a Copy a ["$$Backup"; copy] . . . where $$Backup is the user-entered filepath

How can I cause the data file to be backed up instead? There must be a simple way, but I haven't found it.

Thanks for any help.

Put the script in the data file and have the interface script call it using Perform Script [ External: Data.fp7 ].

A genuine "ahaa" moment . . .
