Iperius is a lightweight, powerful and flexible Hyper-V backup software. In fact, it can perform backups of Microsoft Hyper-V virtual machines (also in incremental and differential RCT mode) and on multiple destinations, such as Tape LTO or NAS, Cloud or FTP, and without limitations in the number of virtual machines or in the size of the data.

Here are the most important features of Iperius for this type of backup:

  • Automatic backup and restore of Hyper-V in RCT mode (incremental and differential) block level
  • Automatic restore also from network and on different hosts
  • Price among the lowest on the market (219 €), perpetual license, free support and updates
  • File level restore (restore of individual files)
  • Extremely light and stable software
  • Standard Microsoft formats, to have always recoverable backups
  • Simple to configure and schedule for automatic backups
  • Compatible with all versions of Hyper-V (Server 2008, Server 2012, Windows 8, Windows 10, Server 2016, Server 2019, etc …)
  • Incremental backup of Hyper-V via block-level image (also with application log truncation)
  • Individual backup of virtual machine files
  • Exclusion of specific disks or virtual machines
  • One license for unlimited virtual machines. Connect to unlimited Hyper-V servers from a single installation, without the need for any agents.
  • Numerous destinations, including Tape LTO, NAS, FTP, CLOUD (Google Drive, Dropbox, Amazon S3, Azure Storage, etc.).
  • Complete utility with numerous other functions, including backup and replication of VMware ESXi and ESXi Free virtual machines

(*Note:  for block-level Image and RCT mode, Iperius Backup has to be installed on the Hyper-V host.  Also,  some configurations will require a license per hypervisor.)

You can read below a short tutorial that will show you how to back up Hyper-V virtual machines:

Once Iperius is installed and started, you can immediately create a new backup job:

Add a special item, the Hyper-V backup, as shown in the image below:

The first thing to do is create a connection account to the Hyper-V server (which in our case will be the local server, where Iperius is installed). To do this, click on the appropriate button shown in the image above. Creating an account is very simple: just specify the Hyper-V server data, entering the IP or the name of the machine and the credentials of an user with Administrator privileges.

Once the account has been created and saved, you can immediately connect to view and select the virtual machines, exactly as you can see them in the Hyper-V management panel:

Select one or more virtual machines, and click on “Next”.

In the next screen, select the Hyper-V backup type.

There are 3 ways you can make the backup:


1. RCT Backup (Resilient Change Tracking) incremental or differential

The backup using the Resilient Change Tracking technology, introduced by version 7.0 of Iperius Backup, allows Full, incremental or differential backup, copying only the modified blocks; choosing for example the incremental backup and setting 3 in the number of copies, Iperius creates the FULL folder and then 3 incremental folders that contain only the differences with the previous backup. This type of backup is therefore very efficient, both in terms of speed (only the actual changes are copied), and in terms of space saving. RCT backup is only available on Windows 10, Server 2016, Server 2019 and above, and is the recommended one.

(It is not mandatory to add additional destinations in the destination panel of the backup job, unless you want to copy the RCT backup to an additional destination, such as Amazon S3 or an FTP server).

You can find more information on this new Microsoft technology starting from this page of the official website: https://docs.microsoft.com/en-us/virtualization/hyper-v-on-windows/reference/hypervbackupapproaches


2. Single Block-level image

This type of backup creates a complete image that includes all the virtual machines (disks and configuration files) in a single image file (VHDX). This will be a backup that will be automatically updated incrementally, at block level, if the destination is a local or external disk.

(It is not mandatory to add additional destinations in the destination panel of the backup job, unless we want to copy the image backup to an additional destination, such as Amazon S3 or an FTP server).

With this backup type, you can individually restore virtual machines in a few clicks using Windows Server Backup.


3. Direct copy of virtual machine individual files 

In this mode, the software can directly copy individual disks and configuration files of virtual machines. With this mode it is also possible to exclude specific disks from the backup (the main one, or the system one, is always included and obviously it cannot be de-selected).

In this case in the “Destinations” panel of the backup operation you will have to add the destinations where to copy the files of the virtual machines, which can be a folder on a local, external or network disk, a LTO Tape, a NAS, a Cloud storage service like Amazon S3 or Google Drive or an FTP server.

The advantage of this type of backup is that it can also be made of Hyper-V servers on the network, without the need for any agent (agentless). With a single license it is therefore possible to backup unlimited hosts and virtual machines that are reachable on the network. The disadvantage, especially compared to RCT backup or block level image, is that it is always a full copy, therefore the software always copies the entire disk files of the virtual machines.

Finally, click on “Next” until you get to the “Summary”, and save the Hyper-V backup item.

If you have chosen the direct copy mode of the files, or if you want to add an additional destination to the backup, go to the “Destinations” panel and add the desired ones, as shown in the image below:

Proceed to set the automatic backup schedule, while leaving all the other options in their default values:

Regarding scheduling and email notifications, we can read the following tutorials for further information:




Finally, let’s choose a name for our backup job and save it by clicking OK.

Now you can immediately run the backup, as shown in the image below:


In a typical RCT backup with one full copy and multiple incremental or differential copies, in the destination folder you will get a folder structure like the following:




To see how easy it is to make a bare-metal restore of an Hyper-V virtual machine, see the following tutorial: https://www.iperiusbackup.net/en/restore-hyper-v-virtual-machines-rct-with-iperius/

To restore individual files (file level restore) from an Hyper-V backup, see the following tutorial: https://www.iperiusbackup.net/en/how-to-mount-vhd-vhdx-extract-individual-files-from-drive-image-and-hyper-v-backups/

Iperius does not use any proprietary format wherever it is possible, therefore backups of the virtual machines will always be recoverable independently of the software, since they are in the standard Microsoft formats.

    Backup HYPERV directly to ftp won’t work since there is an error in the path created by IperiusBackup. Creating and running the same backup using SMB works fine, but is very slow and unusable for us since we have about 3TB to backup daily. SMB puls only 1MB/s and FTP does on average 80MB/s.
    For example (hint: look fo …/\…):
    E:\HYPERV\Virtual Harddisks\SRV1_5CAD5ADB-0308-4E2D-A4F8-CBA1C1CF0A54.avhd (Prohibited file name: /BACKUP-SERVERS/SRV1 test hyperv/\SRV1/SRV1_5CAD5ADB-0308-4E2D-A4F8-CBA1C1CF0A54.avhd ) (31-3-2016 11:41:54

    Is it possible to use Hyper-V backup with Iperius to backup cluster (5 nodes) from one place (one hyperv host?)

    ps. we are looking software to backup HV

  3. Bryant Lim

    I have 2 Hyper-V servers, and have a tape drive connects to one of the Hyper-V server. Can I use the iperius backup in the Hyper-V server with tape drive connected to backup VMs locally and VMs on another Hyper-V?

    1. Iperius Backup Team Article Author

      You have to install Iperius on both the servers. The server that hasn’t the tape drive installed must make the backup to the other server, to one of its disk or to a NAS. On the second server, you can make the Hyper-V backup directly to the tape, adding also the Hyper-V backup of the other server.

    Hi guys,

    I am testing Iperius to back up Hyper-V VMs to Azure. I need incremental backup (of course) in order not to send over the Internet tens of GB and occupy a lot of storage in Azure. Hyper-V in Windows Server 2016 has very complex mechanism for exposing the changed disk blocks that Iperius is hopefully able to benefit of.

    When I set up the backup destination of my Hyper-V job, the only options I get is “Hyper-V: Create a full backup each time and copy all files”.

    Is there a way to set up incremental backups for my Hyper-V VMs?

    Sergiu Pol.

      currently it is not possible to use the “CBT” technology in Hyper-V 2016 with Iperius, to only back up changed clocks. The incremental backup type is only available when you use the image backup mode, but only to local destinations. The transfer to azure will be still a full backup.

      The good news is that we’re working to add the support for incremental backup of changed blocks on 2016. Almost surely it will be released this fall.

    Hi, I’m just trying to test a backup of a hyper-v virtual machine. I installed Iperius on the host and hit the button to try the full version. Then I attempted to setup a backup and created an account to connect to the host admistrator account. That worked but no virtual machines show up in the list to choose for backup. What am I missing please?
