Ensure 'Maximum number of error log files' is set to greater than or equal to '12'
Описание
SQL Server error log files must be protected from loss. The log files must be backed up before they are overwritten. Retaining more error logs helps prevent loss from frequent recycling before backups can occur. The SQL Server error log contains important information about major server events and login attempt information as well.
