I had recently shared a few queries related to SQL Server BackUp over here:
The msdb database stores details of all backup and restore operations. Now if you want to retrieve back up information of all your databases on your server, then here’s the query to do so:
SELECT database_name, user_name as ExecutedBy, physical_device_name,
FROM msdb..backupset bckset
INNER JOIN msdb..backupmediafamily bckfmly
ON bckset.media_set_id = bckfmly.media_set_id
Note: I have run this query on a new setup hence do not have many backup’s.
