Configuring Hard Drive Type or Group
You can configure installed hard drives to perform the following functions:
• R/W (Recording Hard Drive): N
ormal recording hard drive.
• Read-only:
Read-only hard drive. The NVR will not record to read-only hard drives.
• Mirror: Mirr
or hard drive. A mirror hard drive can be used to automatically backup video
footage recorded to the recording hard drive. When a mirroring hard drive is installed, the
NVR 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.
NOTE: Mirror hard drive must be as large or larger than primary hard drive to backup all
r
ecordings. Backup begins from when mirror hard drive is installed and configured.
To configure hard drive types on the NVR:
1 If you are configuring a hard drive to be a mirroring hard drive, you must first format both the
re
cording hard drive and mirroring hard drive before you can set up hard drive mirroring.
For instructions on how to format hard drives, see “Formatting the Hard Drive” on page 44.
