When critical systems fail, every second counts. Downtime doesn’t just disrupt productivity — it erodes revenue, damages customer trust and strains your team. Yet, in today’s hybrid environments, rapid recovery remains elusive at times — especially in modern virtual environments where more granular control is needed for recovery or migration.

At Unitrends, we’re committed to delivering a world-class business continuity and disaster recovery (BCDR) experience that helps businesses stay operational through any disruption. Our latest feature, vDisk Export, is a major step forward in recovery performance and precision for virtual environments. When critical VMs fail, every second matters. However, traditional recovery methods often require restoring the entire VM, even if it’s just to recover a single disk. This “all or nothing” approach is time-consuming, inefficient and frustrating. vDisk Export solves this by allowing IT teams to restore individual virtual disks (vDisks) in their native formats quickly and without extra conversion steps.

Let’s explore how this new capability takes recovery speed, flexibility and efficiency to the next level.

The problem: Recovery has been ‘all or nothing'

For years, recovering data from virtual environments like Hyper-V, VMware or Kernel-based Virtual Machine (KVM) has often followed a rigid, all-or-nothing model. Even if only a single virtual disk was affected, IT teams were forced to restore the entire virtual machine.

This outdated approach creates multiple challenges:

  • It inflates recovery time objectives (RTOs), extending downtime when speed is critical.
  • It consumes unnecessary compute and storage resources, often just to retrieve a small portion of data.
  • It delays resolution when the issue is limited to a minor disk or volume corruption.
  • It adds complexity in hybrid or multi-hypervisor environments, where format conversions and manual intervention slow things down even further.

When every second counts, this recovery bottleneck becomes more than just inefficient — it puts business continuity at risk.

The solution: Precision disk recovery with vDisk Export

With the new vDisk Export feature, Unitrends eliminates the need to perform full virtual machine restores just to recover a single disk. IT teams can now restore individual virtual disks in their native formats without additional tools or time-consuming conversions.

If you’re protecting Hyper-V, vDisk export enables you to restore individual disks in VHD or VHDX format. For VMware environments, you can restore directly in native VMDK - all from agentless backups. No need to recover the full VM and no need to jump through extra steps.

For organizations running KVM-based virtualization platforms such as KVM, QEMU or Proxmox, you can now restore disks in RAW format directly from image-based backups. This allows full access to disk-level data needed for recovery, migration or repurposing.

This enhancement gives IT teams a smarter, faster way to manage recovery.

  • Reduce RTO by eliminating full system restores.
  • Improve flexibility across Hyper-V, VMware and KVM environments.
  • Streamline workflows for testing, migration or targeted recovery.

It’s a significant step forward for organizations working to minimize disruption and keep operations running smoothly.
