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.

In the main menu, from Setting->Storage-> Schedule, you can highlight
redundancy button to enable this function.

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.
Please note only read/write disk or read-only disk can backup file and support file
search function, so you need to set at least one read-write disk otherwise you cannot
record video.
Note
About redundancy setup:
 If current channel is not recording, current setup gets activated when the channel
begin recording the next time.

If current channel is recording now, current setup will get activated right away, the
current file will be packet and form a file, then system begins recording as you have
just set.
After you completed all the setups, please click Save button.

menu->Setting->Storage->HDD Manager)). System needs to reboot to get setup
activated. Now you can search or playback file in redundant disk.
