The Backup built-in outputstream attribute is not supported on applications deployed to Windows. It is valid only for MCP-based logic.

Backup is a read-only built in outputstream attribute that is used to retain report or printer output directed to TP devices.

The use of Backup with outputstreams is similar to the use of the Glb.Backup built-in segment attribute with reports.
