Hot Spare Configuration
Only certain NVR models support this function.
With hot spare configured, when the working device fails, the hot spare takes over service of the
working data. When the working device restores normal status, it takes over service from the hot
spare, and data saved to the hot spare during the period of failure is transferred back to the
working device to ensure reliable and consistent data storage.
1.
Click System > Hot Spare.
2.
Select a working mode, Normal (default mode) for working device, or Hot Spare for hot
spare device.
Normal
You must add a hot spare device after choosing this mode; otherwise, hot spare does not take
effect. Click
Custom Add and then enter device information, including IP address, port number
and password. The username is fixed to admin. Click Add .
Hot Spare
Select Hot Spare , and the current device will be a hot spare for other working devices. All the
working devices that the current hot spare serves are listed.
NOTE:

After the working mode is changed, the NVR will restart with some parameters and
settings changed.

For a working device that switches to a hot spare, some of its functions will be
unavailable, and some settings will be reset to defaults.

If multiple working device fail at the same time with only one hot spare device
available, one working device gets backup at a time.
