2.6.2 Redundancy
Redundancy function allows you to memorize record file in several disks. When there is file
damage occurred in one disk, there is a spare one in the other disk. You can use this
function to maintain data reliability and safety.

button to enable this function.
z In the main menu, from Main menu->Setting->Storage->HDD Manager, you can set one or
more disk(s) as redundant. You can select from the dropdown list. System auto
overwrites old files once hard disk is full.

function, so you need to set at least one read-write disk otherwise you can not record video.
