Find retention policy for orphaned backup files?

[FireExit]

Hi,
When I delete a backup job, an alert pops up:

> Deleting backup job will detach existing backups. Detached backups can be found under the Orphaned node and are still subject to their last known time-based retention

Since I can't look in the job anymore to see what the retention is, and the properties of the backup don't seem to show it, how can I find what Veeam is using as the retention policy for a backup?
