Feature Request - Veeam Replicas to spread across cluster

[gingerdazza]

Hi. It is odd to me that after targeting a VMware cluster for Veeam replications, it picks a single host to replicate to. Would be great to have an option to "spread VMs evenly across cluster nodes" to scale out the replication process.

Hi Dazza,

Thanks for your feature request, but I believe DRS should re-balance all the VMs when you power them on during a DR situation, right?

Thanks!

If you have DRS, yes, but not if you don't. Moreover, this isn't necessarily about re-balance after power up, this is potentially about higher performing replicas scaled across multiple servers in NBD mode. If you have a 10 node cluster, it seems a shame that all NBD IO passes through a single host interface. Surely better to distribute the replica task across the host resources you have? It must be an easy task to code Veeam GUI to round-robin the target hosts behind a cluster?

Yes, this might improve the overall throughput when bottleneck is reported as target, though it also depends on how many VMs you're replicating at the same time and what hardware you have for the target hosts. Thanks for the feedback anyway!

I have noticed this behavior as well.
If I move the replica VM's using vcenter to a bunch of different hosts on the cluster will Veeam leave them there or move them all back to the single host on the next replica run?

No, Veeam will not move them back for sure.

No, Veeam will not move them back for sure.

Surely another reason why this function needs a little development attention. Good and functional, but quite some way from optimal. Would really appreciate some improvements here by Veeam devs. Don't initially sound like a huge code change on face value and would certainly give some added value to us admins. Thanks

[Gostev]

Sorry, what function? Based on what you are quoting - do you expect Veeam to move them back?

[ITP-Stan]

I think we all expect Veeam to initially balance them over the Cluster round-robin style instead of putting them on 1 host.
