You can create a backup of the database of System settings, user rights and settings, and device configurations, which can be restored in case of failure. If a user creates the backup in the Client, the file is saved as a *.db file. Nx Witness creates a database backup automatically whenever the product version is updated and when Systems are merged (see "Merging Systems"). If the backup is created automatically, the file is saved as a *.backup file.
The System database does not include archives, server data, or local settings.
The default database backup location is C:\Windows\System32\config\systemprofile\AppData\Local\Network Optix\Network Optix Media Server on Windows and /opt/networkoptix/mediaserver/var on Linux.
IMPORTANT: It is best to backup and restore the database on the same computer.
