Mirroring
By recording the same data on 2 HDDs that have the same
capacity, you can reduce the risk of losing recorded data in
the event of sudden crash of Main device. As the same data
are recorded on 2 HDDs, the recordable time is halved.
Notice
• Before changing the HDD operation settings (such as
turning the mirroring ON from OFF or OFF from ON
and changing the partition settings), set the pre-alarm
time of the alarm and emergency recording settings to
0 second. After setting the pre-alarm time to 0 second,
check that the PRE ALARM and ACCESS indicators
go out and then change the HDD operation settings.
Step
1 Put a checkmark in the box of [Activate the
mirroring mode].
Notice
• When you enable the mirroring function with the
recorded data stored in the HDD, the recorded data
are deleted.
• You can enable the mirroring function of this recorder
only when both of the internal HDDs A and B are set
as [Main].
• The mirroring function of this recorder can be used
with the internal HDDs only. To mirror data on external
HDDs, use a device having the mirroring function and
refer to the operation manual of the device to be used.
• In case of a failure in either HDD during mirroring, the
recorder continues recording on the normal HDD only.
When you replace the failed HDD, the data are
automatically copied to the newly mounted HDD
and they recover to the status before the failure.
(Data synchronization) When the synchronization is
interrupted by power-off, it resumes when the power is
turned back on.
• Preliminary recording is not performed while the
operation settings of normal, mirroring, or partition are
being changed.
