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.
Free Evaluation – We analyze host logs, storage layout, and virtual disk integrity, then quote a fixed recovery cost
Bit-Level Imaging & RAID Reconstruction – We clone each underlying drive/LUN, rebuild arrays, and extract raw virtual-disk files
VM & File Verification – We repair VMDK/VHD metadata, mount the guest OS, and verify application data before delivery
