Because virtualized systems comprise a unique marriage of software and hardware components, the successful data recovery of inaccessible or lost data requires superior knowledge of hypervisors, host machines, storage devices, RAID arrays, file structures, applications, and more.

Ontrack's global team 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.Ontrack Data Recovery experts can help with following

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

Man Recovering Virtualized System Data

Virtualized 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.

Our data recovery process.

Contact our specialists for a free consultation immediately if you’ve experienced data loss on the virtualized 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.

In lab services

Our industry leading tools guarantee the complete removal of data from all types of storage media. Once you send your media to us, we provide an erasure certificate for your records and can also dispose of your media in an environmentally friendly manner.

  

Remote Data Recovery

Remote Data Recovery 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.

Onsite Services

If your data is too sensitive to leave your location, or you want to outsource the service, we can help. We provide secure data destruction on site for any type of device. We can also dispose of the media for you and provide an erasure report for audit and compliance.

Virtual System Case Studies

Ontrack Provides Database and Backup Restores After a Flood.

Feb 20, 2020, 16:20 PM
Title : Ontrack Provides Database and Backup Restores After a Flood.
Client :
Dell Equallogic™, Storage Area Network, VMware ESX base and RAID 10 backup server.

A flash flood in Baden-Wurttemberg, Germany in Spring 2016 permeated the walls of a server room in a hobby and art supplies store, severely affecting the IT system.

Vast amounts of water flooded into the server room affecting two Dell devices: an EqualLogic SAN with 96 hard drives and a RAID 10 backup server with 12 hard drives.

The storage capacity of the SAN hard drives was between 300 and 700 gigabytes and the backup server contained 24 terabytes of data. About 30 terabytes of data were lost when the SAN volume and the iSCSI connections for the SAN in a VMware ESX Server were damaged. Due to the importance of the data and that most of it contained critical customer information, an emergency recovery was arranged with Ontrack. Several SAN virtualized LUNs running in a VMware environment were prioritized as critical information, with one of them storing a particularly important Oracle database that needed to be recovered as soon as possible. The client also needed to recover two additional LUNs with important data, as well as all the data on the backup server.
After working with the client to assess the data loss and prioritize the data that needed recovering, it was determined that the hard drives in both systems needed to be processed simultaneously. All the hard drives were picked up by Ontrack and delivered to the data recovery lab in Boblingen, Germany.

Upon arrival, the hard drives were initially processed in a cleanroom environment to safely remove dirt and inspect the full extent of the damage. The data on each hard drive and its server location were also documented at this time.

Fortunately, the drives in the SAN had no mechanical problems and could be read properly. However, some of the drives from the backup server were faulty and these had to be processed further in the cleanroom in order to extract copies of the data.

The SAN data recovery was very complex, as the water damage interrupted the connection to the VMware ESX Server and the power supply while in operation. This meant that the mapping links to the EqualLogic SAN and the LUNs in the VMFS datastores (as well as the Oracle database and other files) were heavily corrupted.

To perform the recovery, Ontrack’s proprietary data recovery software tools were required to reconstruct the system and the file structures in order to get to the actual files. However, reassembling the Dell backup server was relatively easy since it hardly experienced any data corruption.
The engineers from Ontrack’s Boblingen data recovery lab succeeded in reconstructing the main points of both affected devices so that the data could be accessed again, including the critical Oracle database and the full backup.

Overall, the customer was very satisfied with the work of the recovery experts from Ontrack. The recovery efforts were also mediated by the Dell Support Team so the data could be restored into a new storage system, as the information required was urgent and needed as soon as the recovery was complete.
