Data Recovery for Corrupted or Infected Backup Systems

The increase in ransomware cases targeting backup files means that organizations that suffer a malware attack can no longer rely on backups to restore important data from critical systems.

We have developed specialized software that allows us to restore critical data files from ransomware-infected backup systems that would otherwise be permanently irretrievable. We’ve had multiple successful recoveries of malware-infected data even when the customer believed they were out of options.


Ransomware

How Can Backup Systems Be Damaged by Malware?

Backing up your data is one of the best ways to protect your devices against data loss. But backup systems can also be infected. In fact, viruses and malware are a common cause of data loss in backup systems.

Viruses can cause a significant amount of damage to your devices, including backup devices, deleting or corrupting large amounts of data. Some malware, for example, is designed to delete or modify data simply to cause destruction, while ransomware encrypts data, making it inaccessible.

The good news is your data isn’t necessarily lost forever. If your data backup system has been damaged by malware, our data recovery experts can help you get your data back using our specialised software designed to restore critical data files from infected backup systems.


How Does Ontrack Recover Data from Infected Backups?

Restoring data from a corrupted backup can be extremely complex as backup data loss may occur at many different levels. For example, Ontrack had a customer that was a victim of a cyberattack on their 64 disk 110TB NAS. The data recovery challenge comprised 4 different RAID LUN configurations, many storage tiers including VMware Datastore, several corrupted 20TB+ VMs, and damaged backups. Ontrack was able to successfully recover the customer’s data relying on the vast amount of experience of our global team of data recovery experts combined with our patented technology. Our teams perform data recovery at all levels with engineers checking for errors at each level and working their way up.

Damaged Backup Recovery Case Studies

Merge files of damaged backup with corresponding virtual files

Feb 24, 2023

The Client

A manufacturing company

Challenge

An international manufacturing company and supplier for airport transportation was hit by a cyberattack. Following their IT guidelines, the company was AIR GAPPING their tape backups on a regular basis. Unfortunately, the restoration of the virtual backup from tape failed and they quickly detected that some tapes were missing. The tapes were found left in the tape library being quick formatted. Originally these tapes belonged to different virtual backup sets. The LTO6 set consisted of 13 tapes and two tapes were missing. In fact, the company was missing three months’ worth of data!

Solution

The Ontrack team was able to join the client’s team for a consultation and scoped out the loss of data, including identifying which tapes needed to be worked on. Based on the scope, Ontrack determined a project plan, expected timing, and expected costs for the recovery. 

All tapes from the tape library and the AIR GAPPED tapes were sent to Ontrack. Additionally, the customer provided all fully intact incremental virtual files separately on external USB drives.

Twenty-four tapes had to be unformatted in several steps. In a subsequent step, two missing tapes had to be identified and the exact order and offsets within a set of 13 tapes had to be determined. As a result, the required 25TB virtual file could be merged.

 

An enormous challenge was still ahead since the virtual backup contained 19 flat files, two of them partly damaged. As expected, the missing data caused native virtual extractor to produce integrity and decompression error messages. Using Ontrack’s proprietary tools, the engineers extracted the virtual files. But, that still left the problem of the 68 incremental virtual files to update to the latest version. Ontrack’s just-in-time software development team provided the necessary tools to complete the merge of the damaged files with the corresponding virtual files to create the most recent irtual files with a total 34TB of data. 

As a final step, the other virtual files were analyzed and only some had to be repaired.

Result

When the client initially introduced the issue, there was little hope for a full recovery, or any recovery, given the complex nature of this specific data recovery task. However, our engineers’ diligence resulted in the creation an unprecedented data recovery solution for all damaged virtual backups, now solely available through Ontrack.

 

The customer was able to fire up most of the VMs with nearly all current data available!
