Veeam on Nutanix and proxy affinity

Veeam Logoby vNik » Tue Mar 14, 2017 5:35 pm

Hi,
I have a general question about the proxy affinity, especially with using Nutanix as HCI.

Nutanix writes all changes locally, so the best and easy way to backup the data is to place a virtual proxy on each node and read the data where the VM is running.
Even after vMotion the new and relevant data for Veeam will be written on the node where the VM is running.

I read about the RegKey “EnableSameHostHotaddMode” to force Veeam to use the local proxy.
Exactly what I was looking for and working very well when I use the hot add virtual appliance mode.

But with Nutanix I am able to let the proxy connect to the NFS share and still read everything locally because the local node is hosting the NFS share.

When I change the settings to use DirectNFS the RegKey is ignored and the proxies are again random assigned.

Is there a way to combine local proxy affinity and the DirectNFS feature?
With Nutanix this would be an amazing feature and reduce the network traffic between the nodes a lot!

Thanks for every idea.

Found the answer on my own in the best practice guide. :oops: :D

In hyperconverged infrastructures (HCI), it is preferred to keep the datamover close the the backed up VM to avoid stressing the storage replication network with backup traffic. If the HCI is providing storage via the NFS protocol (such as Nutanix or Cisco HyperFlex), it is possible to force a Direct NFS data mover on the same host using the following registry key:

Path: HKEY_LOCAL_MACHINE\SOFTWARE\Veeam\Veeam Backup and Replication
Key: EnableSameHostDirectNFSMode
Type: REG_DWORD
Default value: 0 (disabled)
Value = 1 - when a proxy is available on the same host, Veeam Backup & Replication will leverage it. If the proxy is busy, Veeam Backup & Replication will wait for its availability; if it becomes unavailable, Veeam Backup & Replication will switch to NBD mode.

I implemented this feature on a customer site who is using a Nutanix infrastructure.
After a few hours of struggle to get this to work, I decided to open a support case.
After uploading a few job logs I got this answer. :(

I just received a confirmation from QA team that EnableSameHostDirectNFSMode option hasn't been implemented yet. It is planned for one of the future releases.
I apologize for the incorrect information in Best Practices book. I've requested to remove this option from the document until the feature will be implemented.
Unfortunately currently there is no possibility to reach the desired behavior automatically.


Looks like there is at the moment no easy option to receive the data locally with DirectNFS and VMware DRS enabled.

That's unfortunate! I had the regkey set as well, but I clearly see multiple proxies (on different hosts) backing up a single VM.
Any timeframe when the feature will be included?

It is currently planned for update 3, but no specific ETA at the moment.
