+## Remarks
+- RESTORE VERIFYONLY FROM *backup_device* WITH LOADHISTORY populates the column of the **backupmediaset** table with the appropriate values from the media-set header.  
+- To reduce the number of rows in this table and in other backup and history tables, execute the [sp_delete_backuphistory](../../relational-databases/system-stored-procedures/sp-delete-backuphistory-transact-sql.md) stored procedure.  
+- For SQL Managed Instance, backupset table only shows the backup history for user-initiated [Copy-Only backups](../../relational-databases/backup-restore/copy-only-backups-sql-server.md). The backupset table does not show backup history for automatic backups performed by the service.
