Restore Data from Backup for Data Protection

The following explains how to reconstruct the Storage Server for the VK-64/VK-16 for maintenance or recovery from a failure.

1. Check that the PC hardware environment has been restored to the former state. Be sure to use the same folder organization as before.

2. Install the VK-64/VK-16.

3. After installation completes, stop the Storage Server from the [Storage Server Configuration] window.

4. Restore the VK-64/VK-16's configuration file to the former location.

The default location is as follows:

Configuration file path for OS other than Windows Vista/Windows Server 2008

<System Drive>:\Documents and Settings\All Users\Application Data\Canon\WebView\NVR\

Configuration file path for Windows Vista/Windows Server 2008

<System Drive>:\ProgramData\Canon\WebView\NVR\

5. Restore the recorded video data file to the former location.

The default location is as follows:

<Save video in>:\WebView-NVR\videofiles

6. Restore the event data file to the former location.

The default location is as follows:

<Save video in>:\WebView-NVR\eventfiles

7. Start the Storage Server from the [Storage Server Configuration] window.

8. Check that the recording operation is performed correctly. Also check that restored video data is played back correctly.

Note

If the [Maximum retained history] setting is used in the [Storage Server Configuration] window and the restored video data contains data exceeding the retaining period, that data will be deleted when the Storage Server starts.

Restore Data from Backup for Data Archiving

The following explains how to restore only necessary files from the data backup for archive.

1. Check that the drive configuration of the PC to which the files are restored is the same as the PC from which the files were backed up.

Be sure that the hard disk has a capacity larger than the total size of the video data files to restore.

2. Install the VK-64/VK-16.

3. Restore the VK-64/VK-16's configuration file to the former location. The default location is as follows:

Configuration file path for OS other than Windows Vista/Windows Server 2008

<System Drive>:\Documents and Settings\All Users\Application Data \Canon\WebView\NVR\

Configuration file path for Windows Vista/Windows Server 2008

<System Drive>:\ProgramData\Canon\WebView\NVR\

4. Uncheck the [Maximum retained history] option in the [Storage Server Configuration] window.

5. Launch the Viewer and delete all the schedules for all the Camera Servers in the [Recording Schedules] tab under the [Settings] screen.

6. After deleting schedules, stop the Storage Server from the [Storage Server Configuration] window.

7. Restore video data files matching the date and time you want to play back to the former location. The default location is as follows:

<Save video in>:\WebView-NVR\videofiles

8. Restore event data files matching the date and time you want to play back to the former location. The default location is as follows:

<Save video in>:\WebView-NVR\eventfiles

9. Start the Storage Server from the [Storage Server Configuration] window.

10. Also check that restored video data is played back correctly.

Notes on Restoring Data from Backup for Data Archiving

• When restoring the configuration file, also the old recording setting information is restored as well. After restoration, the PC may start recording video according to the old recording schedule. If you do not want to record video, delete the recording schedules after restoration.
• If the [Maximum retained history] setting is used on the Storage Server, uncheck this option. If this option is enabled, the past data may be lost.

Examples

Configuration 1: Backup for Data Protection 1

Premise

5 units of VB-C50i

Recording condition

Frame rate is 1 fps (one frame per second), Camera Server video quality is 50, resolution is 320x240, the size for one image data is 15 KB.

The [Maximum file size / duration] option in the [Storage Server Configuration] window is set to six hours.

Under this condition, the video file size per Camera Server per day is 310 MB x 4 files.

Therefore, the video data quantity per Camera Server per day is 1.25 GB and 6.25 GB for five Camera Servers.

Hardware requirement

6.25 GB per day x 30 days = 190 GB Hard disk capacity of around 240 GB is required.

If the storage period of video data on the Storage Server is 30 days, an archive backup for 1-week data can be saved on 50-GB tape with an AIT drive. To save 30-day data on a single cassette of tape, a 200-GB LTO drive is necessary.

Configuration 2: Backup for Data Protection 2

Premise

10 units of VB-C50i

Recording condition

Frame rate is 1 fps (one frame per second), Camera Server video quality is 50, resolution is 320x240, and the size for one image data is 15 KB.

The [Maximum file size / duration] option in the [Storage Server Configuration] window is set to six hours.

Under this condition, the video file size per Camera Server per day is 310 MB x 4 files.

Therefore, the video data quantity per Camera Server per day is 1.25 GB and 12.5 GB for ten Camera Servers.

Hardware requirement

12.5 GB per day x 30 days = 375 GB Hard disk capacity of around 450 GB is required.

If the storage period of video data on the Storage Server is 30 days, and the required archive period is 180 days, an archive backup for 1-week data can be saved on 100-GB tape with an LTO drive (Ultrium). If you use a 400-GB LTO drive, you can save 30-day data on a single cassette of tape.

Configuration 3: Backup for Data Archiving

Premise

5 units of VB-C50i

Recording condition

Frame rate is 1 fps (one frame per second), Camera Server video quality is 50, resolution is 320x240, and the size for one image data is 15 KB.

The [Maximum file size / duration] option in the [Storage Server Configuration] window is set to six hours.

Under this condition, the video file size per Camera Server per day is 310 MB x 4 files.

Therefore, the video data quantity per Camera Server per day is 1.25 GB and 6.25 GB for five Camera Servers.

Hardware requirement

6.25 GB per day x 30 days = 190 GB Hard disk capacity of around 240 GB is required.

If the storage period of video data on the Storage Server is 30 days, and the required archive period is 180

days, an archive backup for 1-week data can be saved on 50-GB tape with an AIT drive. If you use a 100-GB LTO drive, you can save 1-week backup data.

However, if the tape capacity for archive is too large, we should consider that it takes too long to find desired data from the restored data.

Configuration 4: Backup from Multiple Storage Servers (Backup for Data Protection)

Premise

100 units of VB-C50i

Recording condition

Frame rate is 1 fps (one frame per second), Camera Server video quality is 50, resolution is 320x240, and the size for one image data is 15 KB.

Twenty Camera Servers are registered in five Storage Servers to record video.

The [Maximum file size / duration] option in the [Storage Server Configuration] window is set to six hours.

Under this condition, the video file size per Camera Server per day is 310 MB x 4 files.

Therefore, the video data quantity per Camera Server per day is 1.25 GB and 25 GB for twenty Camera

Servers.

Hardware requirement

25 GB per day x 30 days = 750 GB Ten servers is required (for each Hard disk capacity of 900 GB or more).

In this case, it is ideal to prepare one backup device for each server for backup. If you use a 400-GB LTO drive, you can save 2-week data on a single cassette of tape. Alternatively, you can prepare two or three servers dedicated for backup, and use network backup for central manage
