„Action When the Threshold Level is Reached
Recording continues, however, the Storage Server starts 
deleting recording files, beginning with old files, and 
issues an event.
Note
 Recording files are deleted, even if they have not reached the 
[Maximum Storage Period]. However, if the oldest file is 
currently in use by the Viewer (for example for playback of 
recorded video), it will not be deleted and the next oldest file 
will be deleted instead. Deletion continues sequentially until 
the free disk space exceeds the threshold again. For details on 
saving files, see Chapter 8.
 Normally, a recording file for which the minimum storage 
period has not elapsed is excluded from deletion. Note that 
such files are also deleted if the free disk space cannot reach 
and exceed the threshold value by deleting all the other files.
Threshold Level Conditions and Calculation Method
The threshold level is considered reached when the 
amount of free disk space drops below the following level.
(Number of cameras + 1) x 64 MB
„Action When the Limit is Reached
The Storage Server stops recording and issues an event 
when the free disk space drops to this level.
The Storage Server resumes recording and issues an 
event when the free disk space increases above this level 
after deleting recording files.
Limit Level Conditions and Calculation Method
The limit level is considered reached when the amount of 
free disk space drops below 64 MB. This level is fixed.

Important
 The threshold level is to protect against reaching the limit 
level. We recommend that you take appropriate measures, 
such as deleting unnecessary recording data, when the 
event for the low remaining disk space notification level 
occurs.
 Storing recordings that cause the threshold level to be 
exceeded increases the load on the Storage Server and may 
cause recording to be interrupt, resulting in incomplete 
recordings. We strongly recommend that you operate the 
Storage Server at below the threshold level.
 Note that the threshold level conditions may be met before 
the low remaining disk space notification level conditions are 
satisfied, depending on the circumstances. For example, a 
large number of cameras with limited disk capacity may 
cause a value for (Numbers of cameras +1) x 64 MB to be 
larger than the value of disk capacity x low free disk space 
notification setting/100.

							8-2
Destinations of the Backup Files
The data that is saved during a backup consists of 
recording data, event data, and configuration files. The 
data is saved to the folders described below.
„Recording Data
:\Canon-NVR\videofiles
The following recording data file is backed up:
Images being recorded are saved to a temporary file on 
the hard disk. By default, a recording file is created and 
saved on the destination drive when the temporary file 
size reaches 1 GB.
Note
 Greenwich Mean Time is used for the time added to the file 
name of the recording data.
 This software uses lossy compression for the recording data. 
You do not need to compress the recording files further using a 
tape drive or other devices.
Temporary Files
The following is a temporary file, before it is made into a 
recording data file by the system. This file cannot be 
backed up using the standard backup method.
„Event Data
:\Canon-NVR\eventfiles
The following event data file is backed up:
Note
Greenwich Mean Time is used for the time added to the file name 
of the recording data.
„Configuration Files
The settings for the Storage Server and the Viewer are 
saved in the following folders on the computer where the 
program is installed. You must back up all of these folders 
to completely back up the configuration files.
Configuration file path
:\ProgramData\Canon\WebView\NVR30\
:\Users\\AppData\Local\
Canon\WebView\NVR30\
Note
 The configuration file names are not displayed unless [Show 
hidden files and folders] is selected in the [View] tab of 
Windows Explorer [Folder Options].
 You cannot use the shadow backup feature.
Notes on Backup
 You do not need to stop recording to back up recorded data 
that is complete. However, the frame rate may change 
because of increased disk I/O load and/or CPU load.
 If you want to restore a backed-up recording file, the computer 
you restore the backup to must have the same drive 
configuration as the original Storage Server. For example, if 
you have a C drive for the original Storage Server system and a 
D drive for recorded data, you will also need a C and a D drive 
for the Storage Server you use when you restore the backup. 
Determine the hard disk capacity based on the volume of data 
to be restored.

Troubleshooting
❏Actions required when recording errors occur
❏Solutions when Viewer problems occur
❏Error messages 
						

							9-2
When a recording error occurs (e.g., data is missing) during playback, you can troubleshoot the cause by checking the 
information in the event log and the Storage Server log file.
If you encounter problems when you use the Viewer, refer to the following solutions:
Viewer and Video windows
Actions Required When Recording Errors Occur
LogCauseActionEventStorage Server
Error: Cannot Connect to Camera CameraServer  
disconnected()A network error may have 
occurred. Look for the cause of 
the error by checking the 
Winsock error code recorded in 
the Storage Server log (P. 9-7).Check the network (hub, cables, 
etc.) for any problems and make 
sure that the camera is 
operating normally.
Recording Frame Rate reduced 
due to high load issues—  The effective recording rate is 
excessively low (below 50%).
 The load on the Storage 
Server CPU may be high. Modify the recording 
schedule.
 Check the current CPU usage 
and terminate any 
applications that are a heavy 
load on the CPU.
Recording Suspended
(Low Disk Space ())— The load from writing recorded 
data to the hard disk may be too 
high.Shorten the maximum storage 
period or consider adding a 
hard disk. Additionally, try to 
modify the recording schedule.
Solutions When Viewer Problems Occur
ProblemSolution
I cannot use the pan, tilt or zoom feature of the 
camera in the video window. Double-click the video window or click [Control] on the [Camera Control] panel 
(P. 6-8).
 If images are being played (the title bar of the video window is gray), you cannot 
operate the camera. Click [Live] on the timeline and get control of the camera.
When I click a video window to display the 
[Video Window] menu, [Record Now] is gray 
(unavailable). But, I can use the feature in 
another video window.Display [Properties] for the video window and check on the 
[Advanced] tab whether the camera is disabled. If the camera is disabled, click 
[Enable Camera]. (P. 3-10).
When I try to use layouts created by other users, 
the [Layouts] menu is not displayed. I cannot 
select a layout.Layouts saved in the [User Layouts] folder cannot be seen by other users.
To allow all users to access layouts created by a user, the layouts must be created by 
a user with administrator permissions and must be saved in the [Shared Layouts] 
folder (P. 4-11).
The quality of live or recorded images displayed 
in the video window is not good.The quality of live or recorded images cannot be changed. The video quality may 
depend on the camera settings of the video window. The video quality for the camera 
can be increased using the settings on the camera.
None of the cameras will record.  Is the network cable for the server properly connected?
 Has there been a power failure?
 If link lamps on the hub (switching hub) and on the network connector on the 
server do not light, there may be a defect in the server’s cable, hub (switch), or 
network connector.
Some cameras do not record.  Is the power and the network connection for the cameras working?
 Do the cameras reply to a ping?
 Can you view live images on the Viewer for the cameras?

I cannot connect to the Storage Server from the 
Viewer. Are the login user name and password correct?
 Is the network connection between the server and the Viewer working?
 Is the IP address of the destination server correct?
 Does the server reply to a ping from the Viewer computer?
 Is TCP port 80 being used by another application?
I cannot view live images.  If “Could not connect to camera” is displayed in the video window, check the 
camera’s power supply and network connection.
 If a message is displayed in the timeline of the Viewer indicating that an error 
occurred when connecting to the camera, check the camera’s power supply and 
network connection.
 If the screen goes blank when the layout is switched, but an image is displayed 
after a few seconds, the number of cameras or the live frame rate setting exceeds 
the performance capabilities of your computer. Reduce the number of cameras, or 
decrease the frame rate.
The Storage Server slows down or it takes longer 
to perform various configuration changes, such 
as registering cameras or recording schedules 
from the Viewer.If the Storage Server is running Windows Vista, use Windows Server 2008 instead.
The Viewer slows down.  The performance of the Viewer depends largely on the specification of your CPU 
and graphics card. When the Viewer seems to slow down, try to reduce the 
number of cameras in the Viewer or decrease the live frame rate.
 If the video quality or resolution setting for the cameras is high, the large amount of 
image data may cause processing to take longer. Try adjusting the video quality 
and video size settings on the camera.
ProblemSolution
Nothing happens when I click any of the 
playback controls. Move the playhead off of the [Live] position.
 You must select a video window before you can play back images. In addition, the 
previous frame and next frame buttons (P. 6-6) and the [Extract] button (P. 6-7) are 
enabled only when one video window is selected.
ProblemSolution
I tried to save a recording, but an error message 
is displayed telling me that no video can be 
found in the selected timeline segment.Make sure that a recorded image is included in the selected portion of the timeline 
(P. 6-5).
ProblemSolution
The [Record Now] feature cannot be used. Make sure that the camera is not disabled on the [Advanced] tab in [ 
Properties]. If the camera is disabled, click [Enable Camera]. (P. 3-10).
The amount of Storage Server disk space usage 
is much higher than the calculated level (P. 1-7, 
P. 7-4) and free disk space is low.When the video quality setting of the camera is high, the amount of data per frame is 
large. In addition, if you are using anti-virus software, the software records 
communication between the Storage Servers and the cameras and the size of that log 
may reach several gigabytes. Change the anti-virus software settings to exclude the 
Storage Servers from the target list.
