Creating a Hyper-V Rapid Recovery Backup Set

Hyper-V Rapid Recovery backup sets allow for much faster restore times than Hyper-V Standard backup sets. Rapid Recovery backup sets can only be stored locally, unlike Hyper-V Standard backup sets. Hyper-V Rapid Recovery is good if you want to back up Hyper-V virtual machines frequently and restore quickly. This guide will show you how to set up a Hyper-V Rapid Recovery backup set.


Hyper-V Rapid Recovery Backup 

This chapter includes the following topics:

  • Deleting Hyper-V Rapid Recovery Revisions

Hyper-V Rapid Recovery Backup Overview

Hyper-V Rapid Recovery is a backup set type that backs up full Hyper-V VMs to local storage and allows you to recover important servers quickly.

Hyper-V Rapid Recovery backups protect VMs in a reverse incremental manner. This method allows the most recent state (and the one most likely to be recovered in a disaster) to be recovered in the shortest amount of time. In addition, this method provides a more stable revision chain and requires no scheduled consolidation.

With changed block tracking and an improved recovery point objective, the rapid recovery backup set tracks changes on protected VMs efficiently. This efficiency allows you to schedule VM backups up to every 15 minutes. In case of a disaster, almost no data is lost because the most recent known good state is only a few minutes old.

The backup storage location is where all the backup data (fulls and incrementals) are stored locally.



Local Storage can be on the following:

  • Directly attached storage location
  • Network share
  • Remote share
  • Standard disk (512)
  • 4K disk
  • Sparse file

When backing up a VHD disk on a 4K disk, the backup data is converted to a VHDX format.

Temporary space of 1 GB is recommended for Hyper-V backups.

Note: The agent must be installed on the Hyper-V host.

Creating Hyper-V Rapid Recovery Backup Sets

To create a Hyper-V Rapid Recovery backup set, perform the following steps.

  1. Navigate to the Computer page.

The Computer page is displayed.



  1. Click the Backup tab.


The Backup Selections page is displayed.



  1. In the Backup Type pane, click Hyper-V Rapid Recovery.


The Select page is displayed.



  1. Click the Backup Name to provide a new name for your backup set or accept the default.
  2. At the Select Storage Location Path field, type a path, or click the Browse button to select the storage location of your backup.

Important! Ensure there is enough space available to host the entire backup and its future revisions.

Note: Changed locations of the destination hosts of the recovery VMs, are not changed until the next backup set is run.

  1. In the Current selection pane, select the virtual machines you would like to back up.


  • Any VMs that already are included in other backup sets are grayed out.
  • A warning icon is displayed for VMs that have not been upgraded.
  • Multiple VMs can be included in the same backup set.

Clicking the arrow image008.jpg at the right of the VM displays more revisions of the VM.

Your selections are displayed in the far-right pane. Click the remove icon image010.jpg to remove any selections or clear the item check box.



  1. At the Name field, type a unique name for the backup set.
  2. After making your selections, click Next.


The Schedule page is displayed.



  1. Accept or edit the default schedule.


  • The default schedule is every hour.
  • Multiple weekly schedules are permitted (if they do not overlap).
  • By the minute, hourly or daily recurrences cannot be mixed with weekly recurrences.
  • There can only be one by the minute, hourly or daily schedule configured.
  • The Allow to Finish check box is always selected and grayed-out.

Your schedule is displayed in the Schedule column. Click the remove icon image016.jpg to delete schedule.

  1. After setting your schedule, click Next.


The Retention page is displayed.




  • You can retain up to 99 revisions per virtual machine. With the default schedule of backing up every 1 hour and keeping 96 versions, up to 4 days of recoverable versions are retained at the storage location.
  • The backup set preserves the current state of the virtual machines only. User-generated snapshots are not saved.
  1. Specify how many recoverable versions of backups at the storage location you would like to retain, and then click Next.

The Advanced page is displayed.



Requirement: You must specify a temporary folder located on a disk with sufficient space. Temporary space of 1 GB is recommended for Hyper-V backups.

  1. At the Temporary Folder field, accept the default, type a new path, or click the Browse button to locate the temporary folder that is used during backing up.
  2. At the Backup Mode section, optionally select the Allow Crash-Consistent Backups check box.

CAUTION! Crash-consistent backups do not preserve the integrity of data for open files of transactional applications on the VM guest OS and may result in data loss.

Definitions: A crash-consistent backup captures all the virtual machine's data at the same time.

An application-consistent backup captures all the data including the data in memory and all transactions in process.


  • When crash-consistent backups are enabled, the virtual machine may become unavailable during the snapshot process.
  • The software attempts to make an application-consistent backup. If unable, a crash-consistent backup is created

Pre-Windows Server 2016 versions display a different backup mode option as shown below.


When enabled, the virtual machine may become unavailable during the snapshot process.

The software attempts an online backup first. If unable, an offline backup is created. The virtual machine is paused and put into a saved state while the snapshot is taken, and then the virtual machine resumes operation. VMs in a saved or a paused state can be backed up. The imported recovery VMs are in a saved state in both cases.

Tip: This mode is useful if an online backup cannot be taken. For instance, if the guest VM has dynamic disks, this mode allows guest VMs to be backed up in a non-quiesced, offline state.

  1. Click Next.

The Summary page is displayed.



  1. After reviewing your selections, click the Create Backup Set button.

If you did not change the default backup set name when creating a new backup set, the following confirmation pop-up is displayed after clicking the Create Backup button.


This feature allows you to create a unique name for the backup set. If you already changed the default backup set name, the pop-up is not displayed.

Optionally, change the backup set name, and click Confirm.

Your scheduled backup is displayed on the Backup Selections page.
