Configuring redundant recording
Setting up HDD redundancy lets your NVR redundantly record a copy of the
videos onto multiple drives as a safeguard against losing all your files in case of
disk failures. This process is also known as mirroring. You must have more than
one HDD in your NVR to set up HDD redundancy.
Redundancy significantly reduces the storage capability of the HDDs. As a result
you need to double your capacity to record video over a given time.
Note: You must set the storage mode of the HDD to Group before configuring
the redundancy. See “Setting up HDD groups” on page 110 for more
information.
To set up HDD redundancy:
1. Click the System Setting icon in the menu toolbar and select Hard Disk.
2. Click the HDD Information tab and select the HDD to be used for
redundancy and click Edit.
3. In the Local HDD Settings screen, select Redundancy.
Verify at least one other HDD is set to R/W (read/write).
4. Click Apply to save the settings and then OK return to the previous screen.
5. In the menu toolbar, click the Video Schedule > Encoding.
6. Select the camera to be used for redundancy.
7. Check Redundant Record/Capture.
8. Click Apply to save the settings.
9. Repeat steps 7 to 9 for other cameras whose files you would like to be
redundantly recorded.
10. Click Back to return to live view.
Note: The HDD set to redundancy stores an extra copy of the recording.
When an HDD is set to redundancy, at least one other HDD must be set to
the R/W status.
