Are your SQL Server database backups effective?

Do SQL backups affect performance?

Backups should not cause performance problems as such operations do not take locks on user objects. There is a I/O load though during back up operations but truly speaking you should first validate the complain. There might be other causes for performance problems if the application is really slow.

How can I tell when a SQL Server backup was last successful?

In SSMS object explorer panel, right-click the database. From the right-click menu select Reports >> Standard Reports >> Backup and Restore Events. In the report, you can expand the Successful Backup Operations section, to see the backup history.

What is the best backup strategy in SQL Server?

A full backup strategy is best for SQL Servers that are relatively small because the entire database is backed up each time. This strategy is the appropriate strategy for system databases such as master, model, and msdb because of their typical small size. Each backup takes longer to run.

How often should I backup SQL Server?

Taking a log backup every 15 to 30 minutes might be enough. If your business requires that you minimize work-loss exposure, consider taking log backups more frequently. More frequent log backups have the added advantage of increasing the frequency of log truncation, resulting in smaller log files.
