Data loss from servers, hypervisors, and virtual machines can be daunting. With over 30 years of data recovery experience, Ontrack Hong Kong has recovered data from virtualised systems for thousands of enterprise customers worldwide.

Although virtualisation adds complexity to the data recovery process, Ontrack Hong Kong can help.

As virtualised systems require both software and hardware components, the successful data recovery of inaccessible or lost data requires advanced knowledge of hypervisors, host machines, storage devices, RAID arrays, file structures, applications, and more.

Ontrack Hong Kong has years of experience and training, a host of proprietary tools, and specialized knowledge gained through unique working relationships with virtual machine software vendors and hardware OEMs that recommend our services. We  can help with following;

  • VMware ESX and vSAN (VMDK files)
  • Microsoft Hyper-V (VHD, VHDX, and AVHDX files)
  • Citrix Xen
  • Oracle VM
  • KVM

Virtualised system data recovery recommendations.

For best results, Ontrack 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.

Data recovery options

Contact our specialists for a consultation if you’ve experienced data loss on the virtualised system.

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.

 

Cleanroom

Our advanced cleanroom facilities increase the amount of data which can be recovered from damaged media. We perform any data recovery where the media needs to be uncased in our secure cleanroom environment to avoid further contamination and recover the maximum amount of data possible.

 

Remote Data Recovery

Remote Data Recovery (RDR) is the best option for cloud recovery due to the speed of the recovery process. It is the fastest was to access and recover your data. This cloud recovery is completed via a secure internet connection using proprietary tools. This method is not only quick, but cost-effective as well.
