OK, so you are using VBA.  To my knowledge, VBA backs up VMs... and you are talking about some image backup which sounds like something already done in the past which you would like to move to backup media now.  If this "image" is not VM, then you can't use VBA.  If this is template VM (eg. used to deploy other VMs), then its backup should be possible.  In such case, you will need to explore logs on both NW and VBA end.

Can you explain what exactly is BM backup appliance in your case, how do you access it and how do you make backup of.

Hi

It is the networker VM backup and recovery appliance.

It is the Vm box that acts as the proxy for Networker to backup VM's.

The client is wanting me to backup one of their master images.

I create the backup policy in  NMC and then via the vsphere web client I edit and select the master image but it does not backup.

I just would like to confirm if these master images they are wanting to backup are actually what networker calls templates. If that is the case then as per page 67 of the manual it is a restriction of networker.

You can specify collections of VMs, such as all VMs in a datacenter or select individual

VMs. If an entire resource pool, host, datacenter, or folder is selected, any new VMs in that

container are included in subsequent backups. If you select a VM, then any disk added to

the VM is included in the backup. If you move the VM from the selected container to

another unselected container, then the VM is no longer part of the backup.

You can manually select a VM to be backed up, which ensures that NetWorker backs up

the VM, even when you move the VM.

EMC Backup and Recovery will not back up the following specialized VMs:

◆ EMC Backup and Recovery appliances

◆ VMware Data Protection (VDP) Appliances

◆ Templates

◆ Secondary fault tolerant nodes

◆ Proxies

◆ Avamar Virtual Edition (AVE) Servers

I'm not sure if offlined VM is supported as I never used it - someone with VBA may have more data on this.

I'm not sure if any correlation can be drawn to vSphere Data Protection Error 30931 Failed to Initiate Backup or Restore | VMware vSphere Blog - VMware Blogs

Hi the reply from the customer is as follows.

This is a powered off machine not a template.  This master image changes regularly hence it is not a template.

I will look at the logs again I did look at the daemon raw but did not see anything untoward and the rap log.

Vm I will have to look at closer i did get this message .

vba com.vmware.vdp.server.error.30931

and have rebooted the VBA and not seeing errors other vm recommendations as far as name done.
