one pve cluster with multiple namespaces in pbs

[michabbs]

I want different vm's to be backed up to different namespaces in the same datastore (for example separate ns for each pve pool). Mostly because they are going to have different retention setup.
Do I have to add the same pbs storage multiple times to the pve? Or do I miss something...?

Yes; one PBS-storage for each namespace:
