Use Hyper-V to replicate Linux vm file share
-
Lets say you have 10 Fedora 28 (could be servers, workstations etc).
You back them up (via NFS) to a file share.
The file share is a vm running on Hyper-V.
You now use Hyper-V's built in replication to replicate from Site A to Site B.The above doesn't make much sense but at first glance it sounds good.
Flame suit is on!
Comment away!***edit: must have a gui

Comment away!What does the machine being Hyper-V or using Hyper-V replication have to do with the situation? That sounds like words to make it sound weird, but just distills down to "copies." So let's reword it without the extra, unnecessary information.
Let's say you back up a file to a file share. You then copy (replicate) that file to another site.
Where is the part you think might be weird?

While I see the value in backing up the entire block device (whole VM) it seems wasteful to do this when you could simply push the individual files offsite, probably much faster.
In terms of the site protection, it makes sense, in practicality I don't know how well it would work. Your backup schedule, Bandwidth both LAN and WAN, disk performance on both sides all could contribute to substantial performance issues.

He only said back them up. He easily is only backing up the data.

@scottalanmiller I think he is wanting to do DR with HyperV replicant. The entire set of VM's to Site B.

The only issue I see here is using the heavy full VM replication to copy the entire file server between sites, instead of just having the data replicated at the OS level.
For example, if you have a file server at site A and another file server at site B, you can just copy the files between them with RSYNC. No need for the Hyper-V replication, no need to copy OSes, no need to have one file server offline while the other is online, no need for dealing with the complications of moving a server to a different LAN, etc. Seems overly complex and heavy for something that could be much simpler.

Well he is, but it's only one VM mentioned, just the VM for the file server.
-
Ah I see, he wants to back up everything to a file server, and then back up that file server to Site B.
The biggest issue I might have with this is uncompressing all of those VMs (or raw data) to restore quickly.

That's not weird. First because it's not, you are copying Hyper-V file(s). Second, because "copy" is "copy" regardless of which copy technology you are using.

A file is a file is a file, this isn't weird in any way.

Yes

Think of using Veeam to back up Linux, or Unitrends to back up Windows. Do either of those seem weird? Yet one is Windows to Linux, the other is Linux to Windows. Nothing weird in the slightest.

Also, I think this "feels" weird because of false associations. Like feeling that Hyper-V is more tied to Windows than to Linux. But it is not. Hyper-V is a hypervisor, not an OS, and made by Microsoft, a Linux and UNIX vendor. Would it be weird to do the same thing with ESXi? KVM? Xen?
Hyper-V runs Linux equally well as Windows. It's not associated with one or the other. Same with Xen, or ESXi. They are just hypervisors, what workloads run on top of them is a separate thing.

Just thought there might be a Linux option that could do the same for $0.00

I hear you, I think those days are long gone.
I don't think of hypervisors (Type1) in terms of Windows or Linux...I mean we run Windows on KVM!! -

From the Linux Foundation, I can't think of any solution that would be a Veeam or Unitrends replacement. But there are definitely backup solutions that are FOSS that can do this for free. UrBackup would do this without any complaint.

I meant replicating via the hypervisor.

In the past (see google) there have been comments about Msft's implementation of NFS.
Would that be a concern? -

Nvm, I thought that said "I meant replicate the hypervisor" not "replicating VIA the hypervisor"
