The hard disk drive (HDD) redundancy function can backup
recorded files. The User can then retrieve files from a redundant
HDD if a single HDD is damaged. This enhanced system data
safety.
The HDD redundancy function performs a double backup of data
from the designated channel to the HDD, so the DVR needs a
standalone hard disk for the redundancy function to be effective.
Hard Disk Redundancy Configuration
Open the Main Menu and then the Storage menu to access
storage configuration. Select an HDD as the redundant drive, and
then click on Setting.
The Redundancy HDD must be an independent drive. The User
can set several hard disks as a redundancy HDD group. Once an
HDD is assigned as a redundant HDD, recorded data can be saved
to both the main HDD and the redundant HDD.
The data on the redundant HDD should be automatically cycled;
the cycle period depends on the recording data and the capacity
of the redundant HDD.
Note: Make sure there are two HDDs, with at least one in the DVR.
One is for read and write and the other for redundancy.
Channel Redundancy Configuration
The User can choose some or all of the channels to back-up. Go
to Configuration→Record
and choose a channel, then check the “Redundancy” box.
Note: Data can only be saved to a normal read/write HDD if
Redundancy is not enabled.
Retrieve HDD Redundancy
The User can retrieve backup recordings from the back-up HDD
when the main R/W HDD is damaged or data is lost. First, shut
down the DVR and remove the damaged HDD, then restart DVR.
Next, go to Main menu→Storage and set the back-up (redundant)
HDD as the main read/write HDD, after which it can be searched.
