Question I'd like to ask about this:

Aside from the fact that the process requires the manual rigor, how does the cost associated with these backups (the bandwidth to stream the deltas, the general unused condition of the backups host/vm backups) scale?

For instance; you have a handful of VMs on a set of hosts. You configure those hosts to back up the VMs to a backup host or two. Now those two backup hosts are in "hopefully never have to use" condition. What is the cost associated with this? At what point is this strategy intractable?

If the backup host is not dedicated to backup, but is otherwise serving VMs, and the host it is backing up dies or needs mainteance, how can you be sure that the backup host will have the headroom to run the backup vms? What if it doesn't?

In the end, what I'm wondering is, if it's better to think in terms of software defined control. If a host serving a VM dies, the control would see this, and bring the VM up via a template on another host that has the available headroom. Loading it's data from the datastore, you'd now be up and running again. Same goes for maintenance; put the first host in maintenance mode, let the VMs be moved to where the control sees it makes sense to move them, perform the maintenance, turn it back on, and let the control redistribute the environment optimally.

Fixed point-to-point replication would seem, in many ways, to be contrary to the notion of really utilizing cloud technology to the fullest.

Any merit to that? If the answer is, "this is mostly for small environments with a few VMs", that's fair, but in a large environment, this would seem to top out fast.

I was just wondering using Hyper-V Replica could I replicate from multiple hyper v host to one off site host. The Idea is to have a copy of our main servers off site that could be spun up i at least on a limited base until the host or data center could be rebuilt.
