internal backup. Once the internal backup is complete, Network Discovery sends that internal backup to the FTP site and/or to the USB tape drive.
When you restore data, you also have two options. You can restore either from the internal backup or from the external backup.
Important: After a restore, there may be phantom alarms on the Health Panel and in the Alarms Viewer for the first sampling period, because the events log has been affected by restoring from an old backup.
Note: Both the backup and restore functions must go through the intermediate backup partition. You cannot backup directly from the active partition to an external site, and you cannot restore from the external site to the active partition.
This is a conceptual diagram of Backup and Restore showing all stages:
