Best Disaster Recovery Solutions for 2022

Disaster recovery (DR) and business continuity have been an essential aspect of enterprise IT for decades. Whether it’s earthquakes, floods, or power outages, DR is there to ensure operations can continue.

But more recently, a lot more has been put on the DR plate. Ransomware has now emerged as one of the key reasons to have a DR plan and DR technology in place. A massive disruption like Colonial Pipeline experienced can be enough to put a company out of business.

“Vendors have traditionally been focused on protecting data from power failures, system failures, and natural disasters and have tended to concentrate on some perimeter-level network defenses,” said Siamak Nazari, CEO and cofounder of Nebulon. “With a cyberattack, it’s more than just data that needs protecting—at risk is really the entire physical infrastructure from applications and operating systems down to low-level firmware and BIOS.

“Organizations require even more sophisticated protection, response, and recovery solutions than what was available even two years ago.”

What is Disaster Recovery?

DR consists of several facets. There are hardware elements such as having a redundant data center, where the enterprise can fail over during an event. In some cases, it consists of the same equipment in several locations, each replicating data to another similar unit. But it also requires software to orchestrate data movement, backup and restore technology to ensure a current copy of data is available, and the ability to recover systems and data rapidly.

In this era of the cloud, the big cloud providers take care of the underlying infrastructure. All that is needed is a connection to the cloud. However it is done, the concept remains the same—to bring systems back up in as speedy a manner as possible with as little data loss as possible.

Disaster Recovery and Ransomware

In the event of ransomware, the enterprise needs to have access to an uncorrupted copy of its data, so it can refuse to submit to cyber criminals’ demands.

 “The current cyber landscape requires organizations to be as equipped as possible for ransomware attacks and other disaster events and must take measures to ensure their data can remain resilient,” said Andrew Silva, technical marketing manager at Zerto, a Hewlett Packard Enterprise (HPE) company.

A resilient approach, Silva added, requires a shift in the way IT thinks about ransomware—from exclusive focus on preventing attacks to being prepared for the eventuality of an attack. It must also encompass a recovery solution that guarantees access to data, without gaps or data loss, in the event of attack, so operations are back up and running without delays.

For example, snapshots have been used to improve recovery point objectives (RPOs) and recovery time objectives (RTOs). But this approach works like a still camera, taking a picture of an environment at a specific time. This type of backup and DR technology offers RPOs measured in hours.

Instead, Silva recommends continuous data protection (CDP) as the best way to achieve real-time recovery from ransomware. That said, many vendors continue to utilize snapshots as one element of comprehensive DR and ransomware protection.

“The explosive growth in ransomware that threatens virtually every company in every industry has heightened the importance of cyber resiliency as a key component of disaster recovery planning,” said Sonya Duffin, a ransomware and data protection expert at Veritas Technologies. “… The goal of ransomware is to bring operations to a standstill, much like a traditional disaster would.

“Making matters worse, ransomware as a service has developed into a lucrative business model, and attackers are relentless in developing creative ways to infiltrate IT environments to capture data and hold it hostage.”

DR trending toward increased data protection and resiliency

As a result, the disaster recovery market is changing to place an increased focus on data protection and resiliency that ensures an organization can get back up and running quickly following a ransomware attack and to do so without having to pay the ransom.

This means today’s disaster recovery solutions must fit into an organization-wide zero-trust strategy and include features like immutable and indelible storage with an internally managed compliance clock to keep backups safe, complete visibility of entire data environments, AI-driven anomaly detection to optimize for the fastest recovery possible and broad backup and recovery options across multicloud environments.

In many ways, DR is playing catch up with the rise in effectiveness of cyber criminals. The global cost of ransomware has risen from $325 million to $20 billion from 2016 to 2021, and on average, only 65% of encrypted data was restored after a ransom was paid. This means organizations need to rethink their DR strategy for ransomware use cases since traditional data protection solutions and DR plans may not work.

“Cyber recovery is a different use case that requires a modern data protection solution; new DR plans and procedures; and multifaceted response team which could include IT, DR, security, legal, a third-party cyber insurance company, and other third-party service providers,” said Darpan Thaker, senior director of product management at Sungard Availability Services. “Organizations need to ensure that all these parties work as a cohesive team in order to fulfill their roles and responsibilities, which also increases the overall complexity of ransomware recovery.”

DR as a Service

Another change in DR, of late, is that it is evolving into an on-demand service. Many vendors now offer disaster recovery as a service (DRaaS), which is a good way to integrate disaster recovery with advanced security and data protection solutions.

Local backups are usually enough to recover IT systems from server failure and other common problems. But a site-wide disaster could destroy those backups and result in major downtime and data loss for a business. DRaaS solutions can help ensure complete and reliable business continuity.

Nebulon’s TimeJump and ImmutableBoot solutions work together to apply a snapshot philosophy in a broader context. TimeJump recovers critical application data as well as the infected operating systems on which that data runs, offering physical infrastructure recovery in under four minutes. ImmutableBoot is a reboot-to-recover solution that enables companies to revert back to a frozen snapshot of a known, good version of the operating system with a server reboot.

Key Differentiators

  • TimeJump and ImmutableBoot allow organizations to recover application data and the OS for thousands of servers dispersed across the globe in four minutes.
  • The solution contains a separate fault domain, which prevents ransomware-encrypted servers from infecting the data protection solution.
  • Users can freeze an immutable known, good server image with desired configurations that can be applied across a large server estate.
  • Nebulon automatically enforces centralized and consistent patch and configuration management—no reliance on device-by-device management.
  • The solutions are designed to reduce threat vectors in (deep) infrastructure.
