VMware data recovery recommendations.

VMware data recovery recommendations.

For best results, VMware recommends you follow these guidelines to protect you from further data loss. These recommendations can help preserve your chances for successful data recovery with Ontrack.

  • Never install data recovery software onto a volume if you require deleted data to be recovered. Installing software, creating, or copying files to the volume can permanently overwrite data in the free space of the volume and make it unrecoverable.
  • If critical data is inaccessible due to accidental deletion, device failure, or corruption, take the volume offline and unmount it immediately.
  • If you choose to attempt data recovery on your own, always work with a backup copy or image file of your data, volume, or VMDK file.
  • Re-initializing or reformatting a problematic volume will remove all data and complicate data recovery attempts.
  • Only rebuild a RAID array if all of its member drives have been completely imaged, or you have a fully functional and verified backup.
  • Never attempt to force a failed RAID member drive online unless you have all member drives imaged.

Our data recovery process.

Contact our specialists immediately if you’ve experienced a data loss to receive a free consultation.

Time can be critical, and the odds for successful data recovery are higher when no previous attempts have been performed. Decades of experience confirm that this is critical for saving your valuable data.


Our certified cleanroom facilities are used when the device components have suffered physical damage, mechanical or electronic failure, and can be shipped to our facilities. A cleanroom allows for the opening of sealed hard drives without exposing the device to environmental factors which could further damage the device.

Remote Data Recovery
Remote Data Recovery

Our patented Remote Data Recovery (RDR) service is the fastest way to recover data when the hardware is still functioning. RDR is often used when the equipment is too large to ship, or when security or compliance policies prevent an offsite recovery. The data recovery is performed remotely via a secure internet connection and is the perfect solution for systems that have suffered data loss such as corruption, accidental deletion, or other file-level issues.

On-site Recovery

If your system is not allowed to be shipped and security protocols do not allow for a remote data recovery, onsite service is the best option for your data recovery. Our technician will travel to your facility to perform the data recovery at your location.

Frequently Asked Questions

Our virtual machine is infected with ransomware. Can Ontrack help?

Ontrack has invested in the continued development of proprietary software to recover data from ransomware-infected storage systems, virtual machines, backup files, tapes, and other storage media.Ransomware incidents vary on the type of payload, and data recovery can be complex. Ontrack provides the best possible solutions for data recovery success.

How does Ontrack recover data from virtual machines stored in Veeam backups?

Our engineers, with 35 years of research, experience, and development in data recovery, have the knowledge and tools to recover your data. Ontrack experts can recover data from Veeam and virtual machines backed up with it, such as from VMware and Hyper-V. All necessary steps are taken to ensure data integrity and recover the data as quickly as possible.

How do you recover data from a virtual environment?

Engineers image drives and read raw data on the disk, determine what the configuration should be and then virtually rebuild the array and gain access to the storage. To do so, Ontrack has developed tools such as those that emulate the RAID controller and rebuild what is missing. The company has also developed a wealth of additional tools to accomplish such things as to prevent further writing of data onto volumes, address the complexities of virtualized files systems and more.

What are the most common virtual machine data loss problems?

Common problems with virtual machines include:
  • Re-formatted 'Datastore'
  • Corrupted virtual disk files
  • Corrupt VMFS Datastore volumes
  • Deleted virtual disk files
  • Deleted snapshots
  • Corrupted file systems
  • Traditional RAID and hardware failures

What options do I have to recover data from a virtual environment?

The good news is that there are a great many ways to recover some and, in many cases, all of the lost virtual data. The first point of entry is at the storage level. It can be possible in some cases to directly recover data from physical drives by taking an image of the drives and reading whatever raw data might be available on the disk. The next option is to attempt to recover data from the logical volumes (LUNs) or RAID. If the RAID controller is available, it can be used to track down the many slices of data spread across virtual disks. By determining what the configuration should be, engineers can virtually rebuild the array and gain access to the storage. If the RAID controller is corrupted, it may be necessary to emulate the RAID controller and rebuild what is missing. The next level up, with each representing a higher degree of recovery difficulty, is the host file system level. In VMware this would be VMFS and in Hyper-V, NTFS or ReFS. In many cases, data isn't available directly at the storage level. But if the right tools are used, recovery experts can trace data from the basic storage data blocks, map it to the host level and recompile it. If that process doesn't provide an adequate recovery, additional tools can be employed to extend further into the guest file system level. By investigating the virtual file system, data recovery specialists can sometimes find data that would otherwise be lost. Finally, it is possible to reach into the guest file level and access data lurking in application files such as SQL, Exchange, SharePoint, Oracle, Office files, ZIP files and more.

Experiences that matter

Ontrack has extensive experience with all types of data loss scenarios. Our goal is to provide our customers with peace of mind in the event of data loss due to hardware failure, human error, natural disasters or cyberattacks.
