Backing up data 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: NVR3_MEDIA_ xxxxxxxx _ yyyymmdd Camera ID Year, month and day the recording started _ hhmmss .edt Time 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. NVR3_UNINDEXED_MEDIA_xxxxxxxx_ yyyymmdd _hhmmss.edt Camera ID Year, month and Time day when recording started Event Data :\Canon-NVR\eventfiles The following event data file is backed up: NVR3_EVENT_ xxxxxxxx _ yyyymmdd Camera ID Year, month and day when recording started _ hhmmss .edt Time 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. 8-2
