[bs].[database_name] as [source_database_name],
[bmf].[physical_device_name] as [backup_file_used_for_restore]FROM msdb..restorehistory rs
INNER JOIN msdb..backupset bs ON [rs].[backup_set_id] = [bs].[backup_set_id]
INNER JOIN msdb..backupmediafamily bmf ON [bs].[media_set_id] = [bmf].[media_set_id]
ORDER BY [rs].[restore_date] DESC
