Use Hyper-V to replicate Linux vm file share

In the past (see google) there have been comments about Msft's implementation of NFS.
Would that be a concern?It's improved, but not applicable here. Your fileserver should be Fedora, not Windows. There should be no Microsoft NFS involved in what you have described.

So you want to replicate backups (a backup repository on a Hyper-V VM) from Site A to Site B? Sure, you can replicate ANY Hyper-V VM from site to site.
But for what purpose?
Purpose: replication, DR, offsite etc.
But none of those are specifically assisted by Hyper-V Replication. If anything, I think it makes it worse. Now I realize you've not mentioned alternatives, but we have. For the purpose of replication, DR, offsite, etc. I would avoid Hyper-V and Hyper-V Replication.

My bad, I was over-thinking.
Yes, with a Fedora fileserver, NFS would be built-in. -
@fateknollogee said in Use Hyper-V to replicate Linux vm file share:
FreeNAS is an option, it has built in replication. (Let me duck while I wait for @scottalanmiller FreeNAS response)
FreeNAS offers NO features. None. It's just a crippled version of other things.
I feel like this thread is just slightly in a case of "being weird." You are looking at weird, inappropriate technologies to handle something super simple and common. Why are you not looking at the "normal, enterprise, free" ways of doing this? Why only bizarre solutions that are either "never use crap" like FreeNAS or totally the wrong technology like Hyper-V Replication?

Yes, with a Fedora fileserver, NFS would be built-in.As would replication.

Just edited my op.
Must have a gui.
Pls point me to the solution since Hyper-V doesn't qualify. -

Pls point me to the solution since Hyper-V doesn't qualify.So the goal or end-game here is to have backups located off-site for DR purposes? Tape works well for that, using any regular GUI backup software.

Yes, kind of.
Tape is not an option, 'coz I don't have tape. -
Hyper-V Replication is hardware redundancy, if a time comes in which your server dies, and you cannot get it back up again in a reasonable amount of time, and the 30 seconds to 15 minutes of data loss is worth it.
It's also very helpful for planned failovers, so you can do maintenance on the host without downtime.
If you want to replicate backups off-site for DR purposes, and you don't really have any options...
I woudl probably set up a Fedora NFS server VM in Site B, then use ReaR on the servers you want to back up, using that NFS server in Site B to back up to.
-
If you need a GUI, than you need to buy something, or use Veeam linux agent free to some storage repository in Site B.

That lacks the replication, though.

Pls point me to the solution since Hyper-V doesn't qualify.Here you go, a GOOD tool, WITH a GUI. Of course, it should go without saying, the GUI is just bad and there is zero reason to use it. It only takes a good tool and makes it less good. But if that's your requirement...

How about a GREAT tool without a GUI? -

Just don't use the GUI.

Why the GUI requirement? Having that rules out the BEST ways to do what you want to do?

Hyper-V Replica would work in this situation with a few caveats.
There is a 15 second limit on replication cycles. If the VMs are running database/active services this could be a problem.
Site link would be key relative to the amount of data changing on those VMs.
If Site A gets flattened then spooling the VMs up at Site B may require some tweaks if Site-to-Site VPN was being used and thus different subnets.
Then there's the need to either shift WAN IP(s) to Site B or flip DNS.

That would be handled earlier in the process by the backup job. If the backup is good, the replication won't cause an issue. If the backup is bad, the replication can't fix it, of course, but will replicate the bad backup. But the only place that this can be addressed is in the backup step, the replication is of backup files, so not at a point in the process where it matters.

"Garbage in garbage out" never seems to go away. It's been the bane of our existence since the switch to image/block based backups. :S
