Virtual Machine Data Recovery

Virtualization brings an extra layer of complexity to a host system and when data loss occurs within a virtual machine, it is critical to select a data recovery provider experienced in VMware recovery or other virtualized systems.

Ontrack is the only company to offer a comprehensive data recovery solution for Microsoft Hyper-V, Oracle VM VirtualBox and Citrix XenServer as well as VMware vSphere virtual systems.

Reasons for Data Loss in Virtual Disks

  • Re-formatted VMware ‘Datastore’ is the volume that stores all of the files associated with the virtual computer volumes.
  • Corrupted virtual disk files (VMDK or VHD).
  • Corrupt VMFS datastore volumes.
  • Deleted virtual disk files (VMDK or VHD).
  • Corrupted file systems.

Virtualised server systems have increased the complexity of data storage; however the abstract concepts of virtualised data storage are very similar to SAN, NAS, and iSCSI LUN models. If you are using Cloud services, your data is most likely stored on virtual disk files and systems by your cloud provider.

Important: If virtual disk files or data are part of a data loss event, it is important to stop using the host server datastore volume and assess the situation before deciding on the best course of action. One option would be to contact Ontrack and discuss the situation with a data recovery engineer.

Data loss failure nodes within the virtualised environment happen in the storage level, the host server’s file system level, or within the virtual disk file itself. In some cases, all of these failures happen at once.

Data Loss on VMware, Hyper-V, Citrix Zen and other Hypervisors

Following a data loss, the risk of continuing to use a virtual host sever datastore volume is that virtual disk file data may be overwritten. Many administrators of virtual computer systems use “thin-provisioning” or other data reduction technologies. This technology grows the virtual disk files on an as-needed basis.

When a data loss happens on a virtual host server, other virtual disk files may grow and overwrite the original data that was lost.

Ontrack was the first data recovery provider to develop solutions for virtualised environments. With 100 data recovery engineers worldwide in over 20 office locations, Ontrack Data Recovery services are trusted by thousands of organisations and users.

The patented Remote Data Recovery service from Ontrack Data Recovery is the most secure and fastest way to search and restore the original data on a host server’s datastore volume. Ontrack engineers understand how data within virtual disk files and datastore volumes is written and what to do to restore critical data that is no longer accessible. Strong relationships with OEMs, such as VMware and Microsoft help our Research and Development team to develop pioneering solutions for complex virtual environments.
