Instant Restore to Hyper-V
Instant Restore to Hyper-V is a feature that can quickly restart a virtual machine directly from a compressed and deduplicated backup file to minimize the downtime of virtual machines. This section guides you through the prerequisites for Instant Restore and how to perform it step by step. Please note that the steps for cross-hypervisor restoration might be slightly different.

Before You Start
Instant Restore can quickly restart a virtual machine directly from a compressed and deduplicated backup file to minimize downtime of virtual machines. Compared with the full virtual machine restore that requires more time and has a full I/O performance, Instant Restore can restart a virtual machine within seconds but has a limited I/O performance.
Note:
- Since all the changes made during Instant Restore will be automatically stored on Synology NAS, please make sure that there is enough space on your Synology NAS.
Launch the Restore Wizard
With Instant Restore, you can launch the restore wizard to restore a virtual machine to its most recent state or any available restore point by doing either of the following:
- Go to Active Backup for Business > Virtual Machine > Microsoft Hyper-V and single select the virtual machine you want to restore. Click Restore to launch the restore wizard and select Restore to Microsoft Hyper-V and Instant Restore.
- Go to Active Backup for Business > Virtual Machine > Task List, select the backup task you want to restore and click Restore to launch the restore wizard and select Restore to Microsoft Hyper-V and Instant Restore.
Note:
- Please make sure the hypervisor is authorized to access and mount the iSCSI target on the Synology NAS. When the system is performing Instant Restore to Hyper-V, a backup image will be cloned to a temporary iSCSI target on Synology NAS, and then the hypervisor will mount the iSCSI target.
- iSCSI Initiator Service on the source server is required to be enabled for the system to perform Instant Restore to Hyper-V.
Restore Wizard
Follow the restore wizard to do the following:
To select virtual machines and restore points:
Select the virtual machines you want to restore and choose a restore point for each of them.
To select the restore mode:
You can select either of the following modes according to your needs:
- Restore to the original location: This option restores the selected virtual machine to its original location while keeping the original name and settings, minimizing the chance of input errors by users. This option will instantly unregister and replace the original virtual machine in the production site.
- Restore to a new location, or with different settings: This option allows you to customize the destination and settings for the restored virtual machine.
To configure restore settings:
- If you select Restore to the original location, you will be directed to the summary page of the restore wizard.
- If you select Restore to a new location, or with different settings, you will need to specify the name and select a folder, hypervisor, and network to restore a virtual machine. The changes which are made to the virtual machine during the Instant Restore process will be stored on Synology NAS.
To apply settings and restore virtual machines:
In the summary step, please check the information of the virtual machine intended to be restored and click Apply to restore it. You will then be automatically directed to Restore Status to monitor the restoration progress.
Enable Power on VM automatically after restoration if you want to run the restored virtual machine immediately. For testing purposes, we advise you not to select this option. Instead, we recommend you to manually disconnect the initial virtual machine from the production network to avoid possible conflicts.
