MICROSOFT HYPER-V GUEST VIRTUAL MACHINE BACKUP & RESTORE GUIDE
1 Overview
What is this software?
Backup App brings you specialized client backup software, namely Backup App, to provide a
comprehensive backup solution for your Hyper-V host machine backup. The Hyper-V module of
Backup App provides you with a set of tools to protect Hyper-V host machine and guest virtual
machines. This includes a machine backup feature and instant recovery feature (with the use of Run
Direct technology), to ensure that mission critical machines are back up and running within minutes
of a disaster.
System Architecture
The following high level system architecture diagram illustrates the major elements involved in the
backup process of a Hyper-V host with Backup App and CBS.
In this user guide, we will focus on the software installation, as well as the end-to-end backup and
restore process using the Backup App as a client backup software.

General Requirement
1.
Backup of guest machines located on a SMB 3.0 shares are not supported.
2.
Backup of virtual machine with pass through disk (directly attached physical disk) is not
supported.
Backup App
1.
Backup App is installed on the Hyper-V server. For Hyper-V Cluster environment Backup
App is installed on all Cluster nodes.
2.
The operating system account for setting up the Hyper-V / Hyper-V Cluster backup set
must have administrator permission (e.g. administrative to access the cluster storage).
3.
Backup App user account has sufficient Hyper-V add on modules or CPU sockets assigned.
Hyper-V Cluster backup sets will require one Backup App license per node. (Please
contact your backup service provider for details)
4.
Backup App user account has sufficient quota assigned to accommodate the storage of the
guest virtual machines. (Please contact your backup service provider for details).
Hyper-V guest virtual machines contain three types of virtual disks:
Fixed Hard Disk.
Dynamic Hard Disk.
Differencing Hard Disk.
When Backup App backs up a Hyper-V guest virtual machines for an initial or subsequent
full backup jobs:
Using fixed Hard Disks it will back up the provisioned size, i.e. for a 500GB fixed
virtual hard disk 500GB will be backed up to the storage designation.
Using Dynamic Hard Disk or Differencing Hard Disk it will back up the used size,
i.e. for a 500GB fixed virtual hard disk, 20GB will backed up to the storage
designation if only 20GB are used.
BACKUP APP
5.
MICROSOFT HYPER-V GUEST VIRTUAL MACHINE BACKUP & RESTORE GUIDE
The default Java heap size setting on Backup App is 1024MB, for Hyper-V backups it is
highly recommended to increase the Java heap size setting to improve backup and restore
performance. (The actual heap size is dependent on amount of free memory available on
your Hyper-V server).
Delta generation of large VHD files is a memory intensive process, therefore, it is
recommended that the Java heap size to be increased to at least 2048MB - 4096MB. The
actual required Java heap size is subject to various factors including files size, delta mode,
backup frequency, etc.
6.
Backup App uses the temporary folder for storing backup set index files and any
incremental or differential delta files generated during a backup job. To ensure optimal
backup/restore performance, it should be located on a local drive with plenty of free disk
space. It should not be on the Windows system C:\ drive.
7.
Backup App UI must be running when a guest virtual machine is started using Run Direct
Restore or when migration process is running.
8.
For local, mapped drive, or removable drive storage destinations with Run Direct enabled
the compression type will always be set to No Compression and data encryption is
disabled to ensure optimal backup and restore performance. The backup set compression
type and data encryption settings will only be applied to CBS, SFTP/FTP, or Cloud storage
destinations.
9.
For ease of restore it is recommended to back up the whole guest machine (all the virtual
disks) rather than individual virtual disks.
10.
Since Backup App version 7.9, a new service CBT Cluster Services (Backup App) is
installed and enabled upon installation / upgrade to version Backup App v7.9.0.0 or above.
11.
Make sure NFS service has started for Run Direct to operate. If the backup destination is
located on network drive, the logon must have sufficient permission to access the network
resources.
12.
CBT cluster service is only applicable to Windows x64 installation.
13.
CBT Cluster Service and CBTFilter will NOT be installed on Windows Server 2016 where a
built-in system called Resilient Change Tracking (RCT) will be used instead.
BACKUP APP
14.
MICROSOFT HYPER-V GUEST VIRTUAL MACHINE BACKUP & RESTORE GUIDE
Check if CBTFilter is enabled. This can be verified by running the net start CBTFilter
command.
Example:
C:\Users\Administrator>net start CBTFilter
The requested service has already been started.
More help is available by typing NET HELPMSG 2182.
Note: For Windows Server 2008 R2, if the following error is displayed
C:\Users\Administrator>net start CBTFilter
System error 577 has occurred.
Windows cannot verify the digital signature for this file. A
recent hardware or software change might have installed a file
that is signed incorrect or damaged, or that might be malicious
software from an unknown source.
The issue may be related to the availability of SHA-2 code signing support for Windows
Server 2008 R2 (https://technet.microsoft.com/en-us/library/security/3033929). To resolve
the issue, install the following patch from Microsoft
https://www.microsoft.com/en-us/download/confirmation.aspx?id=46083
Restart the affected server afterward for Backup App to operate properly.
Hyper-V Server Requirement
1.
The Hyper-V management tools are installed on the server. For Hyper-V Cluster
environments Hyper-V management tools is installed on all Cluster nodes.
2.
The Hyper-V services are started on the server. For Hyper-V Cluster environments the
Hyper-V services are started on all Cluster nodes.

If Integration services is not installed / updated on a guest virtual machine or the guest
operating system is not supported by Integration Services, the corresponding virtual
machine will be paused or go into a saved stated during the snapshot process for both
backup and restore, and resume when the snapshot is completed. Furthermore, the
corresponding virtual machine uptime will also be reset to 00:00:00 in the Hyper-V
Manager.
5.
Installing or updating Integration Services guest virtual machine(s) may require a restart of
the guest virtual machine to complete the installation.

6.
For Hyper-V 2008 R2 server in order to use Run Direct restore feature the "Microsoft
Security Advisory 3033929" security update must be installed.
Please refer to the following KB article from Microsoft for further details:
https://support.microsoft.com/en-us/kb/3033929
7.
For Run Direct Hyper-V Cluster backup sets the storage destination must be accessible by
all Hyper-V nodes.
8.
For Hyper-V Cluster backup sets the guest virtual machines must be created and managed
by the Failover Cluster Manager.
9.
The guest virtual machine will not start up if the virtual disk containing the guest operating
system is not restored.
BACKUP APP
MICROSOFT HYPER-V GUEST VIRTUAL MACHINE BACKUP & RESTORE GUIDE
Limitations
1.
Backup of guest machines located on a SMB 3.0 shares is not supported.
2.
Backup of virtual machine with pass through disk (directly attached physical disk) is not
supported.
3.
For backup of individual virtual disks, the restored virtual machine does not support the
reversion of previous snapshots, if the snapshot contains disks which are not previously
backed up by Backup App.
4.
A guest virtual machine can only be restored to the Hyper-V server with the same version,
i.e. backup of a guest on Hyper-V 2012 R2 server cannot be restored to Hyper-V 2008 R2
Server or vice versa.
5.
The guest virtual machine will not start up if the virtual disk containing the guest operating
system is not restored.
6.
Restore of individual virtual disks is only supported using the Restore raw file option for a
virtual disk with no snapshots.
Note
This will require modification of Hyper-V guest configuration files, and this only should
be done if you have in-depth knowledge and understanding of Hyper-V, otherwise the
guest virtual machine may not startup properly.
BACKUP APP
MICROSOFT HYPER-V GUEST VIRTUAL MACHINE BACKUP & RESTORE GUIDE
3 Run Direct
Hyper-V Run Direct is a recovery feature introduced in Backup App version v7.5.0.0, it helps to
reduce disruption and downtime of your production guest virtual machines.
Unlike normal recovery procedures where the guest virtual machine(s) are restored from the backup
destination and copied to production storage, which can take hours to complete. Restore with Run
Direct can instantly boot up a guest virtual machine by running it directly from the backup file in the
backup destination; this process can be completed in minutes.
The following steps are taken when a Run Direct restore is initiated:
Delete Guest Virtual Machine
Backup App will delete the existing guest virtual machine on the original or alternate location
(if applicable).
Create Virtual Hard Disk Image Files
Empty virtual hard disk image files are created on the Hyper-V server (either on the original
location or alternate location).
Create VSS Snapshot
A VSS snapshot is created to make the backup data read only and track changes made
within the guest virtual machine environment.
Start Up Virtual Machine
The guest virtual machine is started up. To finalize recovery of the guest virtual machine,
you will still need to migrate it to from the backup destination to the designated permanent
location on the Hyper-V server.
Copy Data
Copy the data from the backup files in the backup destination to empty hard disk images on
the Hyper-V server.
Apply Changes
Apply any changes made within the guest virtual machine environment to the hard disk
image files on the Hyper-V server.
Delete VSS Snapshot
The VSS snapshot will be deleted after the Run Direct restoration is completed.
BACKUP APP
MICROSOFT HYPER-V GUEST VIRTUAL MACHINE BACKUP & RESTORE GUIDE
The restored virtual machine, at this stage (e.g. before the restore is finalized) is in a read-only state
to avoid unexpected changes. All changes made to the virtual disks (e.g. operation within the guest
virtual machine) are stored in a VSS snapshot created for the Run Direct restore. These changes
are discarded when Run Direct is stopped, where the restored guest virtual machine will be removed
and all changes will be discarded, or the changes will be consolidated with the original virtual
machine data when the restore is finalized.
For more details on Run Direct restore options, refer to Restore Options.

4 Granular Restore Technology
What is Granular Restore Technology?
Backup App granular restore technology enables the recovery of individual files from a guest VM
without booting up or restoring the whole guest VM first.
Granular restore is one of the available restore options for Hyper-V backup sets from Backup App
v7.13.0.0 or above. Backup App makes use of granular restore technology to enable a file level
restore from a virtual disk file (VHD) of guest VM backup possible. It is particularly useful if you only
need to restore individual file(s) from a guest VM which would normally take a long time to restore
and then startup before you can gain access the files on the virtual disks. Granular restore gives you
a fast and convenient way to recover individual files from a guest VM.
During the granular restore process, the virtual disks of the guest VM can be mounted on the HyperV host or on another Windows machine as a local drive. This will allow the individual files on the
virtual disks to be viewed via the file explorer within Backup App or from the Windows File Explorer
on the Windows machine you are performing the restore on, without having to restore the entire
virtual machine. Granular restore can only mount virtual disks if the guest VM is running on a
Windows Platform. The mounting of Linux/Unix file systems from virtual disk file is currently not
available due to limitations of the file system drivers. It is supported for all backup destinations, i.e.
CBS, Cloud storage, or Local/Network drives.
IMPORTANT
Granular restore requires an additional OpenDirect / Granular restore add-on module license to
work. Contact your backup service provider for further details.
BACKUP APP
MICROSOFT HYPER-V GUEST VIRTUAL MACHINE BACKUP & RESTORE GUIDE
How does Granular Restore work?
Benefits of using Granular Restore
Comparison between Granular Restore and Traditional Restore
Granular Restore
Introduction
Granular restore allows you to quickly mount virtual disk(s) directly from the backup file of a
guest VM, so that individual files from virtual disk(s) can be exposed via the file explorer on
Backup App, or to be copied from the file explorer on to a 32 bit or 64 bit Windows machine
you are performing the restore.
BACKUP APP
MICROSOFT HYPER-V GUEST VIRTUAL MACHINE BACKUP & RESTORE GUIDE
Pros
Restore of
Entire Guest VM
Not Required
Compared to a traditional restore where you have to restore the entire
guest VM first, before you can access any individual files/folders,
granular restore allows you to view and download individual files,
without having to restore the entire guest VM first.
Ability to
Restore
Selected Files
In some cases, you may only need to restore a few individual file(s)
from the guest VM, therefore, granular restore gives you a fast,
convenient, and flexible tool to restore selected file(s) from a guest VM
quickly.
With traditional restore methods, if you wish to restore individual file(s)
from a guest VM, you will have to create two different backup sets; a
Hyper-V guest VM backup set and a separate file backup set for the
file(s) you wish to restore. You will required an additional Backup App
installation on the guest VM environment, with Granular Restore
feature, only one backup set is required.
Only One
Backup Set
Required
 Fewer CAL (Client Access License) required – you will only
need one Backup App CAL to perform guest VM, Run Direct, and
Granular restore.
 Less storage space required - as you only need to provision
storage for one backup set.
 Less backup time required – As only one backup job needs to
run.
 Less time spent on administration - As there are fewer backup
sets to maintain.
Cons
No Encryption
and
Compression
To make ensure optimal restore performance, the backup of the guest
VM will NOT be encrypted and compressed, therefore, you may have to
take this factor in consideration when using this restore method.
Traditional Restore
Introduction
The traditional restore method for guest VMs, restores the entire backup files to either to the
original VM location or another a standby location. The files or data on the guest VM can
only be accessed once the guest VM has been fully recovered and booted up.
Pros
BACKUP APP
Backup with
Compression
and
Encryption
MICROSOFT HYPER-V GUEST VIRTUAL MACHINE BACKUP & RESTORE GUIDE
Guest VM is encrypted and compressed, therefore is in smaller file size,
and encrypted before being uploaded to the backup destination.
Cons
Slower
Recovery
As the entire guest VM has to be restored before you can access any it’s
file(s) or data, the restore time could be long if the guest VM size is large.
Two Backup
Sets and
CALs
Required
If you only wish to restore individual files from VM, two separate backup
sets are required, one for the VM image and the other for the individual
files, and therefore two CAL (client access licenses) are required.
Requirements
Supported Backup Modules
Granular restore is supported on Hyper-V backup sets created and backed up using Backup App
v7.13.0.0 or above installed on a Windows platform with the Granular Restore feature enabled on
the backup set.
License Requirements
An OpenDirect / Granular restore add-on module license is required per backup set for this feature
to work. Contact your backup service provider for more details.
Backup Quota Storage
As compression is not enabled for Granular backup sets, to optimize restore performance, the
storage quota required will be higher than non-Granular backup sets. Contact your backup service
provider for details.
Operating System
Backup App must be installed on a 64 bit Windows machine as libraries for Granular only supports
64 bit Windows operating system. Backup App must be installed on the following Windows
Operating Systems:
Windows 2012
Windows 2012 R2
Windows 2016
Windows 8
Windows 8.1
Windows 10
Temporary Directory Requirement
The temporary Directory Folder should have at least the same available size as the guest VM to
be restored and should be located on a local drive to ensure optimal performance.
Available Spare Drive Letter
BACKUP APP
MICROSOFT HYPER-V GUEST VIRTUAL MACHINE BACKUP & RESTORE GUIDE
One spare drive letter must be available on the Windows machine for the granular restore process,
as the VHD virtual disk is mounted on Windows as a logical drive. Backup App will automatically
take the next available drive letter in alphabetical order for the mounted virtual disk.
Note
1. The Windows drive letters A, B, and C are not used by granular restore.
2. The granular restore assigned drive letter(s) will be released once you exit from Backup
App UI.
Network Requirements
Recommended minimum network speed is at least 100Mbps download speed.
The network bandwidth requirements will increase in proportion to the size of the guest VM and or
the incremental delta chain length to ensure optimal performance. Working with limited network
bandwidth may severely affect the granular restore performance.
You can use an online network speed test website (e.g. www.speedtest.net) to get an idea of the
actual bandwidth of the machine.
Other Dependencies
The following dependencies are required for restore and therefore they are verified by Backup App
only when an granular restore is performed. Absence of these dependencies will not affect the
backup job but would cause the granular restore to fail.
Microsoft Visual C++ 2015 Redistributable (x86) / (x64)

9 Restoring Hyper-V Guest Virtual Machines
Restore Options
There are two major types of restore options, namely Run Direct Restore and Non Run Direct
Restore.
Run Direct Restore
Start up the guest virtual machine directly from the backup file without restoring the guest virtual
machine to the Hyper-V server.
Type 1 – Start up a guest VM from Backup Destination without Auto Migration
Enabled
The guest VM data will not migrate to the destination until you manually trigger this action by
following the steps in Migrate Virtual Machine (Permanently Restore). If manual migration is not
performed, any changes made during the Run Direct instance will NOT be committed to backup
files.
Type 2 – Start up a guest VM from Backup Destination with Auto Migration Enabled
To start up the guest virtual machine directly from the backup file and then start restoring the guest
virtual machine files to the Hyper-V server. VM data will start migrating without the need trigger a
manual migration. Any changes made during the Run Direct instance will also be committed to the
Hyper-V server as well.
Non Run Direct Restore
Conventional restore method where Backup App will restore the guest virtual machine files to the
Hyper-V server
Type 1 – Restore to the same Hyper-V server
For this type of restore, you can choose from one of the following restore methods.

Restore the entire guest VM to the original location

Restore the entire guest VM to another drive or folder on the same Hyper-V server

Restore individual virtual disk to original/different guest virtual machine
Type 2 – Restore backed up guest VM to another Hyper-V server on a different host
BACKUP APP
MICROSOFT HYPER-V GUEST VIRTUAL MACHINE BACKUP & RESTORE GUIDE
You need to have the same version of Hyper-V server together with Backup App installed on the
machine where you wish to restore the guest virtual machine. Refer to the steps in Initiate Restore
of VM to another Hyper-V Server on Different Host for details.
Granular Restore
Backup App makes use of granular restore technology to enable a file level restore from a
virtual disk file (VHD) of guest VM backup possible. It is particularly useful if you only need to
restore individual file(s) from a guest VM, which would normally a long time to restore and then
boot up before you can gain access the files on the virtual disks. Granular restore gives you a
fast and convenient way to recover individual files on a guest VM.
For more details about Granular Restore, refer to the Granular Restore section.
BACKUP APP
MICROSOFT HYPER-V GUEST VIRTUAL MACHINE BACKUP & RESTORE GUIDE
10 Run Direct Restore
Requirements and Limitations
1.
Restored guest virtual machines using Run Direct containing a saved state will not
automatically power on. The saved state must be manually deleted in Hyper-V Manager
and the guest must be powered on manually.
2.
For Run Direct enabled backup sets the storage destination is restricted to Local, Mapped
Drive, or Removable Drive.
3.
When a guest virtual machine is started in a Run Direct instance is stopped any changes
made within the guest environment will be lost, if the guest virtual is not migrated to the
Hyper-V Server using the “Auto migrate after Run Direct is running” option.
4.
When a guest virtual machine is started using Run Direct Restore all backup jobs (manual,
scheduled, and continuous) for the related backup set will be skipped.
5.
When a guest virtual machine is started using Run Direct Restore the following features are
not available for the backup set; Data Integrity Check, Space Freeing Up, and Delete
Backup Data.

Initiate Restore of Guest Virtual Machine to another Hyper-V
Server (Different Host)
This restore option allows you to restore your backed up guest VM to another Hyper-V host, for
example if your original Hyper-V host is down and you need to restore your production guest VM’s to
a standby Hyper-V host.
Requirements and Limitations:
1.
Backup App must be installed on the Hyper-V Host where you wish to restore the guest VM.
2.
The same Backup App backup account must be used.
3.
The correct encryption key is required if the backup set was created with the encryption key
feature enabled.
4.
A guest virtual machine can only be restored to another Hyper-V server with the same
version, i.e. backup of a guest on Hyper-V 2012 R2 server cannot be restored to Hyper-V
2008 R2 host or vice versa.
5.
A guest virtual machine backed up from a standalone Hyper-V host can only be restored to
another standalone Hyper-V host. A guest virtual machine backed up from a Hyper-V
Cluster can only be restored to another Hyper-V Cluster.
6.
Guest VMs backed up to local drive / mapped drive / removable drive on the original HyperV host, can be restored to another Hyper-V host only if the new machine has access to the
original drive(s).
7.
The default Java heap size setting on Backup App is 1024MB, for Hyper-V restore it is
highly recommended to increase the Java heap size setting to improve performance.
Especially guest VM’s with many incremental delta files. (The actual heap size is
dependent on amount of free memory available on your Hyper-V host).
8.
The temporary directory should be set to a local drive for best restore performance. Also,
the temporary directory must have sufficient free disk space for the guest VM restore, for
example, the restore of a 500GB guest VM with 30 incremental files of around 5GB each
(500GB + 150GB (30 x 5GB)), the temporary directory will require at least 650GB of free
space.
9.
Restore guest VM’s to original location is possible only if the disk setup on the new Hyper-V
hosts is the same as the original Hyper-V host, for example if the original guest VM was
backed up on G: drive. Then restore to “Original location” can be selected if G: drive is
setup on the new Hyper-V host. Otherwise, select “Alternate location”.
BACKUP APP
MICROSOFT HYPER-V GUEST VIRTUAL MACHINE BACKUP & RESTORE GUIDE
10.
The Hyper-V management tools are installed on the new Hyper-V host. For Hyper-V
Cluster environments Hyper-V management tools is installed on all Cluster nodes.
11.
The Hyper-V services are started on the host. For Hyper-V Cluster environment, the HyperV services are started on all Cluster nodes.
12.
The Microsoft Hyper-V VSS Writer is installed and running on the new Hyper-V host and
the writer state is Stable. This can be verified by running the vssadmin list writers command.
