The explanation of the Parameter attribute backup in the Protocol Development Guide mentions
Indicates whether the parameter has to be added to the backup script of the DMS element.
What's meant with the backup script of the DMS element? I could not find any references to this kind of backup script in the Automation Script Reference. Does anyone know if and how the backup attribute can be used in scripting?
When you had that option defined on the parameter you could right click in Element Display on create backup. This would in the background create an automation script that would contain sets for all the parameters marked as backup.
Note that you couldn't specify an order in which the sets needed to occur. Not sure if this is still available in Cube.
