4. Configure the remote replication schedule

For example, to enable the NVR to copy the recording data automatically to the

remote storage device at 01:15 every Monday, please do the following:

Select ‘Replication Schedule’, select ‘Weekly’, enter 01 Hour: 15 minute, and

select ‘Monday’.

5. Select the backup options

 Select ‘Replication Now’, the NVR will back up the recording data to the remote

storage device immediately.

 Select ‘Overwrite the oldest recordings when the available storage on the remote

host is less than 4GB’; the NVR will overwrite the oldest recording data when the

free space on the server is less than 4GB.

 Select ‘Perform mirroring replication by deleting extra files on the remote

replication’, the NVR will synchronize the recording data between itself and the

remote storage device and delete any extra files on the remote storage device.

When the above options are all selected and remote replication is executed, the NVR

will do the following:

i. The NVR checks if there are files on the remote storage device that are different

from the local source. If yes, the differentiated files will be deleted.

ii. Next, the NVR checks the free space of remote storage device. If the free space

is larger than 4GB, the remote replication will be executed immediately.

iii. If the free space of the remote storage device is less than 4GB, the NVR will

overwrite the recording data of the oldest day and then executes the remote

replication.
