RAID mode setting

If you enable the RAID (Redundant Array of Independent Disks) mode, when a system HDD is damaged you

can restore data safely. This NVR supports RAID Level1. The RAID Level1 supported by this NVR maintains the

same data on the two HDDs that constitute the RAID Array. This means that even when one HDD fails, the

stored data can be used and recovered.

• Status : Displays the operational status of the RAID.

Active : Signals the fact that the RAID is operating normally.

Degraded: This is displayed when one of two HDDs constituting the RAID array has a fault.

Replace the HDD and proceed with recovery before the remaining HDD fails.

` For more on how to replace the HDD and to restore the RAID, refer to "Recovering RAID Array". (Page 38)
