virtual machine data recovery

VMware, Hyper-V, KVM & more

Corrupted VMDK or VHDX? Deleted snapshots? We recover VMs others can’t.

why virtual machines lose data - even in redundant environments.

Snapshots, thin provisioning, and shared storage add resilience - but they also introduce new failure points. When a datastore corrupts or a VM gets deleted, our engineers use low-level imaging and RAID reconstruction to rebuild your virtual disks and restore critical workloads.

supported hypervisors & recovery scenarios.

we recover data from:

  • VMware ESXi / vSphere, vSAN, VVols (VMDK)

  • Microsoft Hyper-V (VHD, VHDX, AVHDX)

  • Citrix Xen / XenServer (XVA, VHD)

  • Linux KVM / QEMU (QCOW2, RAW)

  • Oracle VM / VirtualBox, Red Hat Virtualization, Fusion & Workstation

  • Deleted, corrupt, or overwritten VMs, snapshots, and datastores

typical vm issues we resolve.

  • Failed disks or damaged RAID / SAN arrays

  • Deleted LUNs, volumes, or datastores

  • Accidental VM deletion or snapshot removal

  • Formatted or overwritten hosts / volumes (VMFS, NTFS, XFS, ZFS, ReFS)

  • Corrupt virtual disks – VMDK, VHD, VHDX, QCOW2, RAW

  • Corrupt guest file systems – NTFS, EXT4, XFS, Btrfs, APFS

  • Hypervisor upgrade or patch failures

  • Malware or ransomware inside guest OS

  • System-table corruption – metadata blocks, bitmap errors

signs of a failing virtual machine or datastore.

  • Frequent VM crashes, BSOD, kernel panics

  • VM stuck in a reboot loop or fails to boot at all

  • “Inaccessible” datastore or unknown partition type

  • Missing snapshots or snapshot chain errors

  • Slow or frozen IO operations, high latency warnings

  • Failed backups or invalid checkpoint messages

  • Hypervisor logs showing read/write or parity errors

what should you do?

  • Power off or suspend the affected VM to prevent further writes

  • Do not delete, clone, or “consolidate” snapshots until assessed

  • Document current RAID configuration, drive order, and storage layout

  • Export host, vCenter, or Hyper-V logs for evaluation

  • Contact us before re-initializing or rebuilding any arrays - each write can overwrite recoverable data

our 3-step recovery process.

  1. Free Evaluation – We analyze host logs, storage layout, and virtual disk integrity, then quote a fixed recovery cost

  2. Bit-Level Imaging & RAID Reconstruction – We clone each underlying drive/LUN, rebuild arrays, and extract raw virtual-disk files

  3. VM & File Verification – We repair VMDK/VHD metadata, mount the guest OS, and verify application data before delivery
