Inexperienced attempts can not only fail but actively corrupt or overwrite the remaining recoverable data, making subsequent professional recovery more difficult, or even impossible.
Commercial software often fails to address the unique complexities of large, fragmented virtual disk files (like VMDK or VHDX) or hypervisor-level corruption (e.g., VMFS). We utilize proprietary tools and advanced technologies specifically designed to analyze, repair, and recover data from these damaged structures.
We provide customized solutions tailored to your company’s specific VM environment, maximizing the chances of successful, complete, and validated data restoration.

Our VM Recovery Process
everaging over 20 years of data recovery expertise, we deploy a streamlined, secure, and systematic process to ensure the successful restoration of your Virtual Machine backups.
How can virtual machine data be deleted?
- Ransomware: encryption of virtual machine files
- RAID storage system failure (card or disk failure)
- Virtual disk corruption or erasure (VMDK, VHD, VHDX, etc.)
- Fully formatted and partially overwritten virtual disks
- Deleted or damaged files inside a VM
Formatting and reinstallation, rewriting
File or partition table corruption on VMFS, ESX or ESXi server systems - LUNs/Volumes inaccessible, deleted or incorrectly sized
- Formatted or overwritten hosts, datastores, volumes and VMs
- Corrupt Datastores or host volumes (VMFS, NTFS, ReFS, XFS, etc)
- Corrupted guest file systems
- Deleted VMs or snapshots
- “Datastore reformatted,
- VMFS datastore volumes corrupted,
- Deleted snapshots,
- Corrupted file systems,
Our advices for recovering virtualized data
Stop using the system to stop all writes to the virtual disk concerned and then immediately make a copy of it on another secure storage device.
Never download new files or software into the virtual environment concerned, as this could result in data being permanently overwritten.
Always work with a backup copy or image file of your data, volume or virtual disk file to ensure that original data integrity remains absolutely intact.
Resetting or reformatting a problematic volume will delete all data and severely complicate any future recovery attempts, potentially making it impossible.

Data Recovery FAQs
Frequently asked questions
Get fast, accurate answers to common questions regarding ransomware and data recovery. Find essential information about ransomware attacks, effective decryption, and AS Data Recovery’s expert support. We guide you from prevention to full recovery, showing how to respond swiftly and strengthen your digital defense against future threats.
What kind of virtual machine issues can you recover data from?
We specialize in recovering data from a wide range of virtual machine problems, including corrupted or inaccessible VM disk files (VMDK, VHDX, VDI, etc.), failed snapshots, deleted virtual machines, host system failures, file system corruption within the guest OS, and even data encrypted or damaged by malware within the VM. We support environments like VMware, Hyper-V, VirtualBox, and more.
Can you recover an entire virtual machine, or just specific files from within it?
We offer both! Our capabilities extend from recovering an entire virtual machine to a bootable state, to extracting specific files, folders, or databases from within a corrupted or inaccessible VM disk. We tailor the recovery to your most urgent needs, whether it’s getting an application server back online or retrieving a single critical document.
What should I do immediately after discovering a virtual machine failure or data loss?
The most crucial first step is to stop all activity on the affected host and virtual disk immediately. Do not attempt to run repair utilities, create new snapshots, or write any new data to the storage. Make a bit-for-bit copy or image of the affected VM disk files or logical volume if possible, and then contact us as soon as possible. Working on copies prevents further damage and maximizes recovery success.
How long does virtual machine data recovery typically take?
The timeframe for VM recovery can vary significantly based on factors such as the extent of corruption, the size of the virtual disk, the type of virtual machine environment, and the specific data required. Once we receive your affected media or files, our initial diagnostic assessment will provide you with a clearer estimate of the expected recovery time and costs.
Is the data transfer secure?
Yes. Security is our priority. We exclusively use the SFTP protocol for all file transfers to ensure maximum security. We also perform an integrity check upon file arrival to confirm the recovered data is 100% identical to the original.

What Our Customers are saying?
Read the testimonials and discover how AS Data Recovery successfully helps businesses secure and recover their critical digital assets.
"When a ransomware attack completely locked down our main Hyper-V host, we thought we had lost two weeks of critical production data. The standard recovery tools failed to read the corrupted VHDX files. Your team’s specialized knowledge in virtual machine structure was the absolute difference-maker. Not only did you successfully repair and restore the virtual disks, but the recovered VMs booted up flawlessly. The speed and expertise in handling our complex virtual environment were outstanding."
A. Miller
"We experienced a critical corruption event on our main VMFS datastore, making several high-priority VMware ESXi machines inaccessible. The situation was extremely time-sensitive. Your VM recovery specialists were responsive, providing an immediate diagnosis. They didn't just extract files; they rebuilt the data structure needed to bring the VMs back online. Their ability to manage and restore complex VMDK files from a damaged datastore saved our entire workflow. We highly recommend their specialized services."
J. Khan
"We had a critical failure on our Proxmox cluster due to a hardware failure that corrupted the underlying storage volume, making all our KVM VMs unmountable. Since Proxmox isn't as widely supported as VMware, we were concerned. Your team quickly developed a tailored strategy, manually extracting and reconstructing the data from the fragmented virtual disk images. The recovery was complete, and we were able to migrate the restored data to a new host with zero data loss. It proved that specialized expertise and a custom approach are vital for complex virtualization environments."
