Make sure the free space on the external storage exceeds that of the backup memory (SRAM). When there is no free space, the backup process will not start.
While running [SRAM Auto Backup], the save functions to the external storage will not run (such as sampling's save in CSV or [Save Data] from the [System Settings], [Display Unit], [Mode] tab). These processes will run once backup is complete.
When [SRAM Auto Backup] is run while a sampling group is saving to CSV (automatic save), or while saving log data using [Save Data] ([System Settings], [Display Unit], [Mode] tab), until the backup is complete, writing to the external storage is paused.
When [SRAM Auto Backup] is run while processes other than a sampling group's save to CSV (automatic save) or [Save Data]'s automatic save of logging data, the backup process will start only after writing to the external storage is complete.
Only one backup file can be saved in the external storage. When backup data already exists in the external storage, the file is overwritten.
You can restore data that has been backed up to the external storage to the display unit using [Transfer] – [Transfer from SD to SRAM] in offline mode.
