Backup and Recovery

What do I need to know about backing up the SQL Sentry database?

  • Incorporate the SQL Sentry database into your existing backup and recovery strategy to meet your business requirements.
  • Refer to the Microsoft documentation for a complete overview of SQL Server Backups.

Additional Information: When monitoring the SQL Sentry database with SQL Sentry, you should build a custom event view to see all backup failures.

Emergency Maintenance

There is a possibility of data loss in the SQL Sentry database if the system goes down. Follow best practices for backups and recovery to minimize potential data loss in an emergency situation.

Important:  Should the system go down, it's important to ensure all services are running correctly once it is back up. SQL Server may have stopped, ensure it has restarted on the SQL Sentry database server. Different components may come back online in an unexpected order. You should restart all SQL Sentry monitoring services to confirm that there are good connections and everything is running fully.
