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.

Ransomware VBK Recoveries on Tape - Server & NAS Systems

Jun 29, 2020, 09:51 AM
Title : Ransomware VBK Recoveries on Tape - Server & NAS Systems
Client :
One weekend in April 2020, a hacker/malware attack using a Prolock Ransomware Trojan hit an international pharmaceutical company. The attack reformatted a 90TB VEEAM staging volume with more than 160 virtual machines using a Windows filesystem. 
The attacked volume was originally also used to back up data to LTO8 tapes at regular intervals. Most of these backup tapes were also in the tape library at the time of the incident and were quickly formatted by the attackers. However, the customer was able to save an original unformatted tape with a fairly old backup date, which was then completely restored to the now empty Windows volume with a total of 6 TB. Only then was Ontrack commissioned to examine data recovery options. The HP server DL380 with the 55 3TB hard disks were transported to Ontrack in Böblingen Germany.
During the diagnosis, a large number of the searched VEEAM vbk files were successfully found on the Windows volume with Ontrack Tools and 27 records were extracted according to a priority list. The restore of the LTO8 tape partially overwrote some of the data sets and damaged the backup files. 

A large part of the data could still be repaired and extracted in several steps.

Later on, 19 significantly older LTO8 quick formatted tape backups were successfully recovered too.The attack also affected numerous European sub offices of the customer. Here were predominantly QNAP NAS systems in use which had stored virtual VMs under VMware, including backup VMs that were partially deleted or internally reformatted with another file system. Ontrack was also able to successfully restore complete backup data in 90% of the seven cases ordered.
