hello,

CREATE NONCLUSTERED INDEX [IX_backupset_database_name_backup_set_id]
ON [dbo].[backupset] ([database_name]) INCLUDE ([backup_set_id])

It's probably because you have a lot of data in the table. If you haven't been cleaning the backup history and you have done a lot of backups since msdb was created that may be the source of the issue. I run a job once a week that runs this command to keep my backup history manageable:

DECLARE @dt DATETIME ;
SET @dt = DATEADD(day, -60, GETDATE())
EXEC dbo.sp_delete_backuphistory 
    @oldest_date = @dt ;
