SQL Server Corruption: How Often Should I Run CheckDB

The frequency with which you should run the DBCC CHECKDB command on your SQL Server database depends on several factors, including the size of your database, the level of activity, and the importance of the data.

For most production databases, it is recommended to run DBCC CHECKDB at least once a day, or more frequently if the database is under heavy use or the data is critical. This will help ensure that any potential corruption is detected and addressed promptly.

If your database is large, running DBCC CHECKDB can be time-consuming, so you may need to schedule it to run during off-peak hours. Additionally, you should consider running DBCC CHECKDB before and after making any significant changes to the database, such as adding or modifying tables, to ensure that the changes did not introduce any corruption.

In summary, the frequency with which you run DBCC CHECKDB depends on the size, activity, and criticality of your database, but running it at least once a day is a good starting point. You may need to adjust the frequency based on your specific needs and the results of the checks.
