16Introduction

Quick reference for troubleshooting

An update for the VSS hardware provider snapshot for Hyper-V, to avoid a

Hyper-V writer crash during backup.

■ Check with Microsoft to see if additional hotfixes have been released:

http://technet.microsoft.com/en-us/library/dd430893.aspx

■ Before starting a backup of a virtual machine, verify that the NetBackup master

server and media server can communicate with the Hyper-V server. Add the

name of the NetBackup master server to the server list on the NetBackup client

and (optional) alternate client.

■ On a virtual machine, Windows shadow storage for a volume (such as C:) does

not have to be configured on the same volume. For instance, shadow storage

for the C:\ volume can be configured on D:\. If the Hyper-V server is Windows

2008 R1 and shadow storage for a volume is not configured on the same volume,

note: Windows hotfix KB959962 must be installed to perform an online backup

of the virtual machine. In this case, if the Hyper-V server is 2008 R1 and the

hotfix has not been applied, the backup is performed offline.

Windows 2008 R2 contains all required hotfixes.

Windows shadow storage is required whenever the Windows Volume Shadow

Copy Service (VSS) creates point-in-time snapshots.

NetBackup for Hyper-V notes and restrictions

The following notes and restrictions apply to NetBackup for Hyper-V:

■ For VSS with disk arrays:

To use a hardware array snapshot, make sure that the hardware array's VSS

provider supports the snapshots that involve the Hyper-V writer. Consult the

release notes of the array vendor or VSS provider.

■ NetBackup for Hyper-V does not support the NetBackup Instant Recovery

feature.

■ The following is due to a Microsoft limitation: NetBackup for Hyper-V does not

support VSS or WMI backup or restore of the vhdx files that are shared among

multiple VMs.

■ To perform Hyper-V backups with the SAN Client feature, install SAN Client on

the Hyper-V server. Do not install SAN Client on the virtual machines. For more

information on SAN Client with Hyper-V, see the NetBackup SAN Client and

Fibre Transport Guide.

Note: The SAN Client feature for Hyper-V is only supported for the VSS backup

method (not for WMI).

18Notes and prerequisites

NetBackup for Hyper-V notes and restrictions

■ The following is due to a Microsoft limitation: If the VM's virtual disk files reside

in a volume or folder that is compressed, NetBackup cannot use the WMI backup

method to create a snapshot of the VM. The snapshot job fails with status 156,

“snapshot error encountered.”

As a workaround, remove compression from the volume or folder where the

virtual disk resides and rerun the backup.

■ NetBackup for Hyper-V supports Windows NTFS file encryption and compression,

for backup and restore. However, it does not support NetBackup’s compression

or encryption options (in the NetBackup policy attributes).

For UNIX or Linux guest operating systems: NetBackup for Hyper-V does not

support any type of compression or encryption, whether they are set in

NetBackup or in the guest OS.

Note: The compressed Windows NTFS files are backed up and restored as

compressed files.

■ If a policy is changed from manual selection to Intelligent policy (or vice versa),

note: The next backup of the VM is a regular full backup, even if a backup already

exists for that VM.

For example:

■ In a new Hyper-V policy, the Select manually option on the Clients tab is

used to select a VM. The first backup from the policy runs.

■ In the policy, an Intelligent Policy query is used to select the same VM, and

the VM is backed up a second time. Because of the switch from manual

selection to query-based selection, this second backup is a regular full

backup. Note that for a policy that uses Enable block-level incremental

backup (BLIB) or BLIB plus Accelerator, the backup processing is not limited

to changed blocks only.

For the second backup, the Detailed status log includes a message similar

to the following:

Sep 29, 2016 11:16:53 AM - Info bpbrm (pid=13680) There is no

complete backup image match with track journal, a regular full

backup will be performed.

The same backup behavior occurs if the policy’s VM selection is switched

from query-based to manual selection: The second backup is a regular full

backup.

■ For the WMI backup method with the Enable block-level incremental backup

option (with or without Accelerator): If the VM has multiple virtual disks that have

19Notes and prerequisites

NetBackup for Hyper-V notes and restrictions

the same disk UUID, NetBackup performs a full backup of those disks. It does

not perform an incremental backup of them. The disks that have unique IDs

undergo an incremental backup, as expected. In the Activity Monitor, the job

details include messages such as the following:

The virtual machine (Name: testVM, GUID: 98321741-A936-4128-8AB0-07099B23E25C) uses

multiple disks with the same disk Id.

Disk Id: 7198C033-AB5D-4585-905D-0DA68D26F9C5 Disk path: E:\VMs\testVM\testVM1.vhdx

Disk Id: 7198C033-AB5D-4585-905D-0DA68D26F9C5 Disk path: E:\VMs\testVM\testVM2.vhdx

You may lose optimization during the backups for the above listed disks.

To perform incremental backup of these virtual disks, assign a unique ID to each

disk. For example, you can use the Set-VHD PowerShell cmdlet to reset the

disk ID for testVM1 as follows:

Set-VHD -Path E:\VMs\testVM\testVM1.vhdx –ResetDiskIdentifier

In the case of the differencing disks, you must run additional commands to

re-create the disk chain. For more details on the Set-VHD cmdlet, see the

following Microsoft TechNet article:

https://technet.microsoft.com/en-us/library/hh848561.aspx

■ Additional notes are available on Accelerator:

See “Accelerator notes and requirements for virtual machines” on page 135.

■ The following is due to a Microsoft limitation: NetBackup for Hyper-V does not

support backup of encrypted vhd or vhdx files.

■ The following is due to a Microsoft limitation; this note applies to the VSS backup

method only. For the virtual machines that have a FAT or FAT32 file system,

NetBackup supports only Hyper-V offline backup.

See “About Hyper-V online and offline backups for VSS” on page 174.

■ The WMI backup method (for Hyper-V Server 2016 and later) does not employ

online vs offline backups.

See “WMI backup method: State of the virtual machine before and after restore”

on page 110.

■ For the VSS backup method: If a virtual machine is in the Paused state when

the backup starts, the virtual machine is placed in the Saved state after the

backup completes.

■ The WMI backup method supports a new Hyper-V policy option: Consistency

level (on the policy's Hyper-V tab under Advanced). The available settings are

Application Consistent Then Crash Consistent, Application Consistent,

and Crash Consistent.

For the WMI backup method, note the following:
