Hi Marianne,
The VM backup host is a physical server.

Apologies for my misunderstanding.
The TN that I posted above should help you to troubleshoot.
Go through the config and verify everything as if it's a new installation.
Check Device Manager, NBU Policy config, etc...
Lastly - enable VxMS log at increased logging level.

Hi,
Could be some intermittence in your SAN? This is strange, your backups are running by SAN transport mode and suddenly change to NBD....What changed in you environment in 1/6/2017 ??
This TN above mentioned by @Marianne is very helpful to this cases.

Hi Thiago,
We had performed some testing on other backup software since 26 May 2017 on the vcenter but this issue happened on 1 June 2017. Not sure if it is related.
Attached here are the vxms log for your further investigation.

Seems like security/SSL issue between backup host and vCenter.
Found this in VxMS log:
07:37:18.0601 : g_vixInterfaceLogger:../libvix.cpp:1844 <DEBUG> : [VFM_ESINFO] 2017-06-14T07:37:18.601+08:00 [07944 error 'Default'] Cannot use advanced transport modes for XXXvc02.abc.com:443/moref=vm-14132/snapshot-47868: Other error encountered: SSL Exception: Verification parameters:

See if this TN applies: http://www.veritas.com/docs/000024646
PS:
You need to upgrade. All NBU versions up to 7.6.x reached EOSL 4 months ago.

Hi Marianne,
The setting has already been set to All for SSL Version in vcenter server setting. Any other findings?

I cannot see anything else - only the SSL error which seems to be a vCenter issue.
Other than logging a call with VMware, I do not have any other suggestions.
Logging a call with Veritas will probably met with:
"Support for your version has ended on 1 February 2017".

Hi Marianne,
Yes, you are absolutely right. Have to plan for upgrade then or change the backup software for good.
