nvr qnap auto backup to another server

Limitations and Restrictions:

  1. Remote Replication is limited to the local network only.
  2. Before using this function, ensure that the Microsoft networking service of the remote storage device is enabled, and that the corresponding path and user access rights have been correctly configured.
  3. The time required by the NVR to replicate the data to the remote storage device will vary depending on the network environment. If the remote replication task takes too long, some recording files may be overwritten by the NVR. To avoid this, it is recommended to refer to the status messages to analyze the time required for the remote replication and adjust the replication schedule accordingly.

Applied VioStor NVR firmware version: QVR 5.0 or above

Steps

1. Login to the QVR desktop and go to ‘Backup & Expansion’ > ‘Remote Replication’.

2. Enable remote replication (supports multiple choices)

In the above example, the NVR only copies the alarm recording data of the latest 3 days to the remote storage device.

  • Select ‘Enable remote replication’ to activate this feature. The NVR will execute an automatic backup of the recording data to the remote storage device according to the settings.
  • Select ‘Back up alarm recordings only (instead of all recordings)’, the NVR will only copy the alarm recording data to the remote storage device. If this option is unselected, the NVR will back up all of the recording data to the remote storage device.
  • Select ‘Back up the recordings of the latest…day(s) only’ and enter the number of days, the NVR will back up the latest recording data to the remote storage device automatically according to the settings. If this option is unselected, the NVR will copy all of the recording data to the remote storage device.

3. Configure the remote storage server

Enter the IP address, path, user name and password of the remote storage device.

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.

6.The NVR displays the latest 10 remote replication records.

In the above example:

  • When the status is shown as ‘Failed (Remote access error)’: Check to see if the remote storage device is running and if the network settings are correct.
  • When the status is shown as ‘Failed (An internal error occurred)’: Check the hard drive status of the NVR and view the Event Logs.

Applied VioStor NVR firmware version: NVR FW v4.2.0 or below

Steps

1. Login to the NVR and go to ‘System Administration’ -> ‘System Tools’ > ‘Remote Replication’.

2. Enable remote replication (supports multiple choices)

In the above example, the NVR only copies the alarm recording data of the last 3 days to the remote storage device.

  • Select ‘Enable Remote Replication’ to activate this feature. The NVR will carry out automatic backups of the recording data to the remote storage device according to the settings chosen.
  • Select ‘Back up alarm recordings only (instead of all recordings)’, the NVR will only copy the alarm recording data to the remote storage device. If this option is unselected, the NVR will back up all of the recording data to the remote storage device.
  • Select ‘Back up the recordings of the last…day(s) only’ and enter the number of days, the NVR will back up the latest recording data to the remote storage device automatically according to the settings. If this option is unselected, the NVR will copy all of the recording data to the remote storage device.

3. Configure the remote storage server

Enter the IP address, path, user name and password of the remote storage device.

4. Configure the remote replication schedule

For example, to enable the NVR to copy the recording data automatically to the remote storage device at 00:00 every Monday, please set the following:
Select ‘Replication Schedule’, select ‘Weekly’, and enter 00 Hour: 00 minute, and select ‘Monday’.

5. Select the backup options

  • Select ‘Replication Now’, the NVR will immediately back up the recording data to the remote storage device.
  • 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 extra files on the remote storage device that are different from the local source. If yes, the extra files will be deleted.

ii. Next, the NVR checks the free space of the remote storage device. If the free space is larger than 4GB, the remote replication task will be immediately carried out.

iii. If the free space of the remote storage device is less than 4GB, the NVR will overwrite the oldest recording data and then carry out the remote replication task.

6. The NVR will display the latest 10 remote replication records.

In the above example:

  • When the status is shown as ‘Failed (Remote access error)’: Check if the remote storage device is running and that the network settings are correct.
  • When the status is shown as ‘Failed (An internal error occurred)’: View the hard drive status of the NVR or view the Event Logs.
