16.3.22 Setting up Hard Drive Mirroring (Advanced)
A mirror hard drive can be used to automatically backup video footage recorded to the
recording (read-write) hard drive. When a mirroring hard drive is installed, the system
can be set to record cameras in parallel to both the recording hard drive and the mirror
hard drive. This way, the footage is automatically backed up if the recording hard drive
fails.
How hard drive mirroring works:
1. Security system.
2. Primary hard drive.
3. Mirror hard drive.
NOTE
• The mirror hard drive must be as large or larger than primary hard drive to backup all recordings.
• HDD mirroring begins from when mirror hard drive is installed and configured.
• Two hard drives must be installed in the system to use HDD mirroring. For details on installing hard
drives, see 22
NR800 Series Hard Drive Installation , page 156.

drive and restart.

Storage>Schedule>Record .
