Challenges for Ransomware-proof Backups

Ransomware is one of the biggest IT threats for companies, hospitals, and public institutions. The attacks are increasingly targeting an organization's last line of defense – the backup.


The latest cases show that advanced ransomware is able to work its way through to the backup in order to compromise or delete the data. In case of an attack, data is encrypted and backup copies are made unusable. The consequences for organizations include data loss, business process disruption, loss of revenue, and ransom demands. Today, it is essential to implement an immutable backup storage which reliably protects your data against ransomware attacks.

Growing data volumes for backups & lack of scalability
Threat of malware, data loss & data integrity violations
Optimization of recovery time and recovery point objectives (RTO & RPO)
High costs & lock-ins for traditional backup targets

Ransomware-proof backup storage

With a backup, you are protected against data loss and ransomware – right? Unfortunately, cybercriminals also know that backups are the last line of defense... and they strike exactly there. Protect your backups with iCAS FS and gain additional efficiency, simplicity and flexibility in data storage.

Backup Guide: How to protect your backups from professional ransomware

Ransomware has become one of the most lucrative criminal businesses. As the attacks are becoming increasingly professional, it is essential to implement an immutable backup storage which protects your data against attacks. 


This backup guide shows you: why ransomware is the #1 threat for companies, hospitals, and public institutions worldwide; what challenges the attacks pose; and how you can reliably protect your backups against cyber-attacks.

How to build a ransomware-proof backup target

Data immutability

Data immutability ensures that data cannot be modified or deleted within a specific retention period. Thus, encryption by ransomware attacks is reliably prevented and a clean copy of your data can be restored.


One method to ensure this is the WORM principle (Write Once Read Many). WORM is a data protection method in which data is written immutably to a storage medium. The files cannot be changed or deleted afterwards by the users. However, they can be read as often as required.


Ransomware can no longer encrypt your data.

Minimized "attack surface"

Employees can inadvertently become the entrance gate for ransomware. Not without reason are phishing e-mails still one of the most frequently used methods of infecting endpoints with ransomware.


The attack surface can be minimized by using external service providers who are subject to strict monitoring. Backups are administered by an external provider and only this provider has access to your backup system. Thus, errors by administrators or IT managers in the company can be avoided and the danger of social engineering can be minimized.


As the IT attack surface is minimized, it is impossible for ransomware to impact the integrity and availability of the system.


A single backup copy is not sufficient.


If there are multiple copies in different locations, it is much less likely that all backup copies will be lost, corrupted, or encrypted by ransomware at the same time. It is important in this strategy that at least two storage targets are also physically separated from each other – to protect you in the event of a fire or natural disaster, for example.


A backup solution that can replicate over long distances (WAN copy) simplifies this task and additionally protects your backups from physical damage.
