Back up log server's database
Handle the log server's database by using the method that you use when handling system configuration as described earlier. The log server's database contains all your system logs, including errors reported by recording servers and cameras. The default name of the log server's database is SurveillanceLogServerV2.
The SQL Server database is located on the log server's SQL Server. Typically, the log server and the management server have their SQL Server databases on the same SQL Server. Backing up the log server database is not vital since it does not contain any system configuration, but you may appreciate having access to system logs from before the management server backup/restore.
