On the remote side, right? It won't be "dedup" if it's your question 🙂 (for now at least).

We are thinking on a smart way to dedup it efficiently 🙂 It's not trivial because we don't have a lot of control on the host itself, but we might find solutions.

You can have one job with 2 remotes. Or a job with backup and DR at the same time.
