Progress of the backup/restoration processing

Backup Function
This function backs up the CPU module data memory and device/label data onto the SD memory card. A new folder is created
during the backup, and the data is backed up with a file format into that folder.
The backup function operates even when the CPU module is in the RUN state.
When executing the backup function with the CPU module in the RUN state, do not change device/label data
during execution of the function. Doing so may cause data inconsistency of the device/label data and the
contents of the backup data may unintentionally change.
Operation Mode
Backup modes include the normal mode and CPU module auto exchange mode. The operation mode is set with SD9350
(Operation mode setting).
