Cannot backup Direct NFS mode

[yihwang]

Hi, I want to use Direct NFS mode with Nutanix.

test environments are below
- each proxy set to each esxi host (vsphere 6.5)
- backup source vm is stored in NFS datastore (v3)
- Set Registry value : EnableSameHostDirectNFSMode = 2 in BnR Server

After test environments was set, it worked perfectly that I want to.
backup job was used only local proxy in same host even if source vm migrate other host.

But, there is a problem after several test changing the value of 1 and adding the Registry value EnableSameHostHotAddMode = 0,1,2
Backup was failed with the error message " index was outside of the bounds of the array".
Even if I restored the condition That it was succeed - EnableSameHostDirectNFSMode=2, delete EnableSameHostHotAddMode,
the result was same - failed.

How can I do to resolve this issue?

Thanks in advance

Hi Yeongil,

Can you contact the support team and provide logs, it will help to find out the real cause of the issue.
Please do not forget to share the case id here, so we can track the issue internally. Thanks!

Hi Yeongil, just to make sure, have you restarted the Veeam Backup Service after changing the registry values?

[yihwang]

Yeah, I'm pretty sure that I restarted Veeam Backup Service after I changed the value.
I plan to test again because the test environment is somewhat different from bp guide of nutanix & veeam in respect of network design.
I'll test it agin with same subnet of all machines - vbr, proxy, source vm, datastore and I'll reply it will work.

Thanks to the advice

It worked well Direct NFS mode with the registry value after I reconstruct test environments.
The problem was my test environments. It seems that the setup was twisted by several tests.
Thank you for your attention.
