4.5.1.2 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.
In the main menu, from Setting to Schedule, you can highlight redundancy button to enable this
function. See Figure 4-13.
In the main menu, from Advanced to HDD management, you can set one or more disk(s) as
redundant. You can select from the dropdown list. See Figure 4-16. 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 can not 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 all the setups please click save button, system goes back to the previous menu.
