On-premises backup: How to balance security, flexibility, and resilience

Redstor posted in Legacy backup | 11 Mar 2025

Cloud. Is. Everywhere. No matter where you turn in today’s data landscape, all the talk seems to be about infinite scalability, global accessibility, and seamless updates. ‘There’s no hardware!’, they gush. ‘We only pay for what we need!’, they rave.

But for many, it’s like hearing endlessly about that amazing new TV show you simply must watch when all you have is books and radio. Countless businesses out there choose not to go down the cloud route for various reasons. Others don’t have a choice due to data residency and security mandates. Banks, healthcare firms, government agencies – we hear you.

Why on-premises infrastructure still matters

Far from heading for extinction, on-premises data storage is alive and well. Many organisations want full control over their data. Others with stable data demands or legacy dependencies are content to keep it that way.

But relying solely on your physical infrastructure without a robust backup strategy is a gamble that no business can afford to take. As the risk of cyber threats, operational disruptions, and ransomware attacks grows, companies that use on-prem hardware face potentially catastrophic dangers.

Fortunately, modern recovery solutions are designed to complement old-school data storage.

Moving beyond traditional backup

Traditional backup solutions are often time-consuming, resource-intensive, and high-maintenance. When your business is already on the back foot following a cyber incident, the last thing you need is further delay. Evolving IT environments call for a hybrid approach.

By combining on-premises hardware with cloud-based recovery, businesses get the best of both worlds. Organisations should ensure that their backup strategies support multiple operating systems, such as Windows, Linux, and macOS, while also integrating with virtual environments like Hyper-V and VMware.

Disaster recovery

Legacy backup solutions often focus purely on data protection without considering the broader implications of business continuity. A robust disaster recovery strategy should include the following:

  • Bare metal recovery: The ability to recover an entire system from scratch, including OS, applications, and configurations.
  • Physical-to-virtual recovery: Transitioning from physical machines to virtual environments during failures.
  • Cloud integration: Restoring systems directly to Azure or other cloud platforms to ensure operational continuity, even if on-premises infrastructure is compromised.

Ransomware resilience

As cyber threats have evolved, ransomware attacks now target backups themselves. If your backup becomes compromised, it’s as useless as not having it at all. The solution is immutable backups, which cannot be altered, encrypted, or deleted – even by the hackers who have infiltrated your system.

Furthermore, the best backup solutions not only store copies of data but also actively scan for anomalies. By taking a proactive approach, you can receive real-time alerts to detect cyber risks before they escalate.

How Redstor supports on-premises backup and recovery

Redstor’s modern backup solutions are designed to support businesses operating in on-premises, hybrid, and multi-cloud environments. We ensure total data protection, rapid recovery, and intelligent automation to help enterprises meet evolving data protection challenges.

Comprehensive OS and platform support

We support a wide range of operating systems, including multiple versions of Windows, macOS, and Linux (Ubuntu, Red Hat, CentOS, SUSE), as well as virtualisation platforms like Hyper-V and VMware. This extensive compatibility means businesses can protect, recover, and manage data across diverse IT environments.

Advanced recovery

Redstor enables organisations to recover their systems in any scenario, ensuring minimal downtime and maximum resilience. From bare metal and physical-to-virtual recovery to Azure-based restoration, we recover entire systems quickly and convert them into virtual machines for maximum flexibility.

Our granular file and system state recovery allow you to restore individual files or complete system configurations with ease, while InstantData™ technology provides immediate access to critical files during recovery.

Intelligent cyber resilience

With the rise of ransomware and other cyber threats, Redstor’s backup solution incorporates multi-layered security features, including:

  • Immutable backups: As discussed above, our backups ensure data cannot be altered, deleted, or encrypted.
  • Automated threat detection: We identify and mitigate ransomware risks before they impact recovery processes.
  • Zero Trust architecture: Redstor uses multi-factor authentication and encryption to slow hackers down once they breach your defences.

Conclusion

Whatever type of data storage model your business adopts, the key to cyber resilience is a multi-layered backup strategy that evolves in line with your needs. Companies that work with Redstor know that even in a worst-case scenario, their data is fully protected.

Legacy backup solutions have their place, but no business wants its legacy to be a cyberattack from which it couldn’t recover. Protect your reputation by getting in touch today.
