I need an sql command (dbcc or extended stored procedure?) or something that can be called from a sql server stored procedure to get the most recent full backup file available f
Just query msdb..backupset (MSDN) on the "source" prod server
And a working example (SQL Rockstar) too
Edit, 2018
SELECT
bs.database_name,
bs.backup_start_date,
bmf.physical_device_name
FROM
msdb.dbo.backupmediafamily bmf
JOIN
msdb.dbo.backupset bs ON bs.media_set_id = bmf.media_set_id
WHERE
bs.database_name = 'MyDB'
ORDER BY
bmf.media_set_id DESC;
