This issue has been solved. See solution.

Hi Guys,

 

We just migrated our Hyper-v virtual machines from 2008 to 2012. I successfully backup the virtual machine, but when i tried to restore the virtual machine I noticed that .vhd is missing and only .xml file is their. Please see attached file for the screenshots.

 

Is this a bug on Netbackup 7.5.0.6 Hyper-v 2012?

 

Thanks.

Seems Hyper-V 2012 is not yet supported.

See Statement of Support for NetBackup 7.x in a Virtual  Environment:   http://www.symantec.com/docs/TECH127089

NetBackup for Hyper-V Compatibility lists Windows Server 2008,Windows Server 2008 R2.

 

**** EDIT ****

According to this blog it is supposed to be supported with NBU 7.5.0.6: 

https://www-secure.symantec.com/connect/blogs/announcing-better-backup-microsoft-netbackup-7506

If you are using the correct NBU 7.5.0.6 W2012 binaries (http://www.symantec.com/docs/TECH204661), probably best to log a Support call.

 

See NBU 7.5.0.6 Release Notes:

■ Support for the following virtualization technologies:
■ Hyper-V for Windows Server 2012.
 
Note: Hyper-V for Windows Server 2012 is supported with some limitations.
See “Virtualization notes” on page 45.
 
■ The following is a list of limitations on NetBackup support for Windows 2012
Hyper-V:
■ Backup and restore of the Resilient File System (ReFS) is not supported.
■ Block-level incremental backup is not supported.
■ File-level recovery from a Hyper-V backup is not supported when:
■ The file originates from a Resilient File System (ReFS) volume, or
■ The virtual machine is composed of VHDX file(s).
File-level recovery continues to be supported when the file originates from
an NTFS volume and the virtual machine is composed of VHD files(s).
■ Backup of virtual machines within Cluster Shared Volumes (CSV) is
supported. In Hyper-V Server 2008 R2, CSV has a limitation that requires
serialized backups. In Hyper-V Server 2012, CSV supports concurrent
backups without that limitation. Consequently, the CSV timeout setting in
the NetBackup Hyper-V policy is only used in Hyper-V Server 2008 R2
deployments.

Hi Marianne,

 

I think our Hyper-v 2012 (Windows server 2012 DataCenter) is supported but with limitations. We noticed that when we backup virtual machine with .vhdx disk the backup is successful and .vhdx appears in the BAR GUI (Please see attached file). The only problem with this is we can't restore file-level recovery.

 

Thanks.

Correct. Your opening post mentioned .vhd, not .vhdx.

As per Release Notes:

■ The following is a list of limitations on NetBackup support for Windows 2012 Hyper-V:
■ Backup and restore of the Resilient File System (ReFS) is not supported.
■ Block-level incremental backup is not supported.
■ File-level recovery from a Hyper-V backup is not supported when:
■ The file originates from a Resilient File System (ReFS) volume, or
The virtual machine is composed of VHDX file(s).
File-level recovery continues to be supported when the file originates from
an NTFS volume and the virtual machine is composed of VHD files(s).

Thanks Marianne! We will just convert our virtual machines with .vhd disk to .vhdx.

Hi Marianne,

 

Symantec support just gave me Emergency Engineering Binary (EEB) for Hyper-v host. This is a known issue on NBU 7.6 for Hyper-v 2012.

If anyone encounters this issue. Please call Symantec Support for EEB.

 

Thanks.
