History Cleanup Task (Maintenance Plan)
Use the History Cleanup Task dialog to discard old historical information from tables in the msdb database. This task supports deleting backup and restore history, SQL Server Agent Job history, and maintenance plan history. Deleting SQL Server Agent Job history is not available on servers running Microsoft SQL Server 2000.
This statement uses the sp_purge_jobhistory and sp_delete_backuphistory statements.
|The addition of the Hour interval in cleanup tasks has implications when you are running multiple version of SQL Server 2005. If you create a task that has an interval of hours, and then try to run that task on either the release version of SQL Server 2005 or SQL Server 2005 Service Pack 1, you will get a different interval. If you edit the task using the earlier versions of the tools, an error message will appear.|
