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.


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.
