Ever tried deleting a database with the "Delete backup and restore history information for databases" ticked, only to find it takes hours? This is because it essentially does table scans on the MSDB database, create the indexes below before deleting and you'll be laughing. Quote CREATE NONCLUSTERED INDEX [IX_backupset_database_name_backup_set_id] ON [dbo].[backupset] ([database_name]) INCLUDE ([backup_set_id]) CREATE NONCLUSTERED INDEX [IX_backupset_database_name_media_set_id] ON [dbo].[backupset] ([database_name]) INCLUDE ([media_set_id]) CREATE NONCLUSTERED INDEX [_ped_backupset_media_set_id] ON [dbo].[backupset] ([media_set_id]) Credit to Peter Edenharter: http://connect.microsoft.com/SQLServe...-intensive Jordon Pilling | Heavencore Administrator
