HDD redundancy function can backup the recording file. Users can then retrieve files

via the HDD redundancy if the main HDD damaged and so preventing lose of data.

double backup in the HDD, so the DVR needs a standalone HDD for the redundancy

function.

as the redundancy HDD and select one to set.

The redundancy HDD must be an independent HDD. User can set several HDDs as a

redundancy HDD group. Once a HDD is assigned as redundancy HDD, the recording

data can be saved in both the normal HDD and redundancy HDD.

Data stored on the redundancy HDD should automatically cycle coverage. Cycle period

depends on the recording data and the redundant HDD’s capacity.

The user can choose which video channels to record to the redundancy backup HDD.

Please go to 【Configuration】→【Record】, choose redundancy channel, check mark

【Redundancy】.

NOTE: the data in channel turn off redundancy only is recorded in normal

reading and writing HDD if the redundancy is not enabled.
