4.4.1.2 Redundancy
Redundancy function allows you to memorize record file in several disks. These
files are created, packaged and closed simultaneously. 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 4-12.
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 4-13.
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.
