virtual machine data recovery
VMware, hyper-V, KVM & more
any hypervisor, any failure
Corrupted VMDK or VHDX? Deleted snapshots? Kotar recovers VMs others can’t.
why virtual machines lose data - even in redundant environments
Snapshots, thin provisioning, and shared storage add resilience - but also create new points of failure.
When a datastore corrupts or a VM gets deleted, our engineers use low-level imaging, RAID reconstruction, and hypervisor-specific tools to rebuild your virtual disks and restore 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, corrupted, 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 or snapshot deletion
Formatted or overwritten 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, or kernel panics
VM stuck in reboot loop or fails to boot
“Inaccessible” datastore or unknown partition type
Missing snapshots or chain errors
Slow or frozen I/O operations, high latency
Failed backups or invalid checkpoint messages
Hypervisor logs showing read/write or parity errors
what you should do
Power off or suspend the VM to stop further writes
Do not delete, clone, or “consolidate” snapshots before assessment
Document RAID configuration, drive order, and storage layout
Export vCenter, host, or Hyper-V logs for evaluation
Contact Kotar before re-initializing or rebuilding any arrays — each write may overwrite recoverable data
our 3-step recovery process
Free Evaluation – We analyze host logs, storage layout, and virtual disk integrity, then provide a fixed quote.
Bit-Level Imaging & RAID Reconstruction – We clone each underlying drive or 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.
