Reduces the size of the backup and restore history tables by deleting the entries for backup sets older than the specified date. Additional rows are added to the backup and restore history tables after each backup or restore operation is performed; therefore, we recommend that you periodically execute sp_delete_backuphistory.
The backup and restore history tables reside in the msdb database.
Applies to: SQL Server (SQL Server 2008 through current version).
The following example deletes all entries that are older than January 14, 2010, 12:00 A.M. in the backup and restore history tables.
USE msdb; GO EXEC sp_delete_backuphistory @oldest_date = '01/14/2010';
