Unavailable operations and functions at the same time as data backup
If any of the following operations and functions are performed during data backup, the backup will be completed abnormally
and the error cause is stored in SD1452 (iQ Sensor Solution backup/restoration error cause in a module).
The error is returned to the request source which performs the operation or function.
*1 Available operations and functions differ between LCPUs and QCPUs. For details, refer to the user's manual of a CPU module used.
When data is backed up or restored during a data logging, the performance of the data logging will be reduced.
Therefore, sampled data may be partially missed and the data missing frequency may be increased.
■ Communication load
When data is backed up or restored, the load of the service processing is temporarily increased. Consequently, a timeout
error may occur in other communications.
To avoid a timeout error, review the value set for "Service Processing Setting" on the [PLC System] tab in "PLC parameter".

Backup folder name
Do not change an underscore and a subsequent number of a backup folder name (date_number).
If they are changed, the data may not be restored properly.
