Hello,

Any feedback?

Hi Riaan,

I need one clarification, for full virtual machine backup, whether i need to install netbackup client in both Hyper-v server and in guest server??

please suggest me.

Thanks

Hello,

To back up the vm container (hyperv policy) you need the client in the hyperv host. To backup and application (sql exchange etc) you need the client in the guest. For single file restore you also need the client installed in the guest, unless you're going to restore to a share/copy the files to the guest.

Hi Riaan,

I got few details for failure.

1. If i uncheck the off-host backup option in the Hyper-v Tab of Policy.

Backup is happening. But the problem is snapshost is not creating for this.

I observed that my vm is having below configuration: 

Eg: C:\ ------------ Disk 1 ---------------- *****.vhd

D:\....................Disk 2 -----------------*****.vhdx

Backup is failing with snapshot Error.

For above symantec is having any limitation like that, virtual machine should not have different type of disk format.

Experts... Plz comment.

Thanks for the reply Riaan, i installed the Netbakcup client in Hyper-v server. while finishing the policy creation, i got the warning message and same attached here. please suggest.

Regards

Hello,

I didn't see this is not your post. Please open a new post with your issue.

Hello,

Do you have " Enable file recovery from VM backup" enabled for this policy? Its not possible to use this option with vhdx so it might be causing an issue.

Best to go through chapter 1 and 2 of NetBackup for Hyper-V Administrator's Guide  carefully.

You will see the following: 

Phase 3:
The VSS Hyper-V writer quiesces the Windows virtual machine and creates
the snapshot on the host volume. If the Hyper-V writer cannot quiesce the virtual
machine, the virtual machine is placed in the Saved state before creation of the
snapshot.

You will find a list of pre-reqs in chapter 2 that includes various MS hotfixes for VSS on the Hyper-V server and virtual machines.

NBU 7.6.x

Hyper-v 2012

vhdx as file system for vms often results in VM going into saved state during backup. 

Solution

Upgrade NBU to 7.6.0.2 and Hyper-V to 2012 R2

This is due to underlying Integration services and vhdx format... Pls recofirm if this is applicable to your environment.
