During processing of command export command, an invalid value is encountered for the BACKDELETE parameter for node node name.
Export processing continues, but the exported data contains an unknown BACKDELETE value for this node. If this data is imported, the default or existing BACKDELETE value is used.
Update the BACKDELETE parameter for this node and restart the export command. Alternatively, use the export data with the unknown value, and check and update the BACKDELETE value after import processing has been performed.
