Using immutable backups is one very effective way to combat ransomware. They provide unchangeable and dependable defenses against data loss brought on by ransomware assaults. Unlike traditional backup systems, immutable backups are made to withstand manipulation, guaranteeing that your vital information stays safe and available even should a breach occur.

This blog will examine why every business should consider including immutable backups in its cybersecurity plan.

What Are Immutable Backups and How Do They Work?

Once produced, immutable backups—copies of data—are not changeable or deletable. This function ensures that the data remains intact and safe, providing a consistent recovery source should a system fail, accidental deletions occur, or cybercrime strike. Using Write Once, Read Many (WORM) technology, these backups guarantee that once data is entered, it cannot be erased or modified.

The degree of security is where immutable backups differ from local backups. Traditional backups, while crucial, are prone to human mistakes or attack vulnerabilities. Often targeting backup systems, cybercriminals destroy or alter backup copies to block recovery following a ransomware assault. Conversely, immutable backups—which offer an unchangeable backup—are meant to be resilient to these hazards.

Even for administrators with enhanced rights, immutable backups are kept in settings that prevent data from being rewritten or erased. This extra layer of security guarantees that backup data stays safe, giving organizations a reliable source for disaster recovery free from manipulation concerns.

Reasons Why Immutable Backups Are Vital Against Ransomware

Immutable backups have proven to be the best approach to preventing ransomware attacks. You need them for several reasons, including:

• Immutable Backups Create an Unchangeable Data Snapshot 

One of the most potent features of immutable backups is their capacity to produce unchangeable data snapshots. A snapshot represents the exact state of your files or systems at the moment of capture. Immutable snapshots guarantee data integrity since they cannot be changed once produced.

Traditional backups are a big risk since they are flexible and can be changed either intentionally or unintentionally. A hacker or insider threat might access the backup files and alter or destroy them, compromising your recovery options. Conversely, immutable snapshots eliminate this risk since the storage system design forbids data change attempts.

These images are a reliable source of recovery, as their unchangeable character guarantees a precise record of your data at particular moments. Immutable snapshots help restore systems to their original, uncorrupted condition in case of a ransomware attack or system failure, guaranteeing minimum data loss and business interruption.

• Safeguarding Ransomware Attack Backups 

Targeting backup systems as vital recovery tools, ransomware assaults are progressively focusing on them. Attackers typically encrypt or destroy backup files when they compromise a network to stop recovery, compelling businesses to pay a ransom to regain access to their data. Nonetheless, immutable backups offer vital protection since they guarantee that backup data cannot be changed or deleted even in cases of network administrator access by attackers.

The main virtue of these technologies is their resistance to ransomware. Ransomware cannot encrypt or destroy the backup copies since the data is locked and safeguarded by methods including WORM and encryption. Organizations may relax even if the primary data is hacked, knowing their unchangeable backups remain unharmed and ready for swift restoration.

This function is crucial to stopping the cycle of paying ransom or coping with a prolonged outage. Without turning to paying attackers, immutable backups offer a dependable approach to recovering from ransomware events.

• Enhance Business Continuity 

Business continuity in the case of ransomware attacks or other disasters depends on timely and effective recovery capability. Ensuring that your company may recover without significant data loss or downtime depends mostly on immutable backups. Unchangeable copies of your data allow businesses to quickly resume activities by means of immutable backups, providing a consistent recovery point.

Recovering data in damaged traditional backup systems may take days, weeks, or even months. With immutable backups, however, companies can restore critical systems in hours, lowering downtime and lessening the effect on business operations. Using immutable backups has helped many businesses significantly increase continuity following attacks and claim far faster recovery times.

With immutable backups, for example, a financial services organization can rapidly restore transaction records in the case of an attack, guaranteeing no disturbance of consumer services or regulatory compliance. To ensure continuous treatment, healthcare professionals can also maintain constant access to vital health data and patient information.

Even with the most disruptive cyber threats, businesses may lower their risk of downtime, hasten their recovery, and preserve business continuity by including immutable backups in their disaster recovery strategies.

• Ensuring Regulatory Compliance 

In fields like healthcare, financial services, and legal advice, operational efficiency and regulatory compliance depend on maintaining data integrity. Many laws, including HIPAA for healthcare or GDPR for data protection, demand companies retain and protect data to prevent undesired access or alteration.

Immutable backups are excellent tools for satisfying these compliance criteria. They guarantee that data is kept in its natural, authentic condition, offering a reliable record for legal and audit needs since they cannot be changed or deleted. For instance, immutable backups help healthcare firms meet regulatory data retention requirements by preserving patient records.

For regulatory audits, unchangeable backups give a clear, tamper-proof data storage record, helping organizations demonstrate industry compliance and avoid hefty penalties or legal action.

• Associated Cost-Efficiency 

Although initial setup costs may involve immutable backups, the cost savings greatly exceed the expenditure over time. Traditional backup systems may require extensive resources to run and maintain. In the case of a ransomware attack, the financial load of paying a ransom or restoring lost data might be exorbitant.

Conversely, immutable backups provide a reasonably priced defense against ransomware infections. By keeping attackers from changing or deleting backup files, organizations can avoid the need for costly ransomware payments. Businesses can also avoid the high expenses of lost productivity, data recovery initiatives, and extended downtime.

Many companies implementing immutable backup systems see notable reductions in operational downtime and recovery expenses. Organizations can rely on immutable backups to rapidly restore data instead of expensive data recovery tools, lowering the need for outside intervention.

When it comes to backup performance, every little detail counts. Unfortunately, some companies tend to oversimplify the discussion, focusing only on a handful of key factors. The reality is much more complex, and ignoring the finer points can put data protection at risk.

In a previous article (“Efficient Backup: Ready for the Black Scenario“), we explored backup methods, the importance of RTO and RPO, and the differences between data storage and backup. But that was just the tip of the iceberg. Now, let’s dive deeper and examine how storage media, network throughput, and data reduction mechanisms impact backup performance. What should you consider when choosing the best solutions for your business?

Storage Media: A Tough Choice

Not long ago, using SSDs in NAS systems (often used for backups) seemed unnecessary. Today, almost every NAS device supports them. One of the loudest voices advocating for ditching traditional hard drives is VAST Data, a U.S.-based company specializing in large-scale data management. Their solution relies entirely on flash storage, offering archive-level data retention at a cost comparable to HDDs. With proprietary technology that extends SSD lifespan to up to 10 years, their systems reduce the need for multiple devices to store and protect data. Perhaps in the future, businesses won’t have to choose between HDDs and SSDs – but for now, that decision still matters.

Flash storage significantly boosts backup performance. For example, a standard SATA SSD can be twice as fast as a mechanical SATA hard drive, while NVMe SSDs can outperform HDDs by a staggering 35 times. That’s a game-changer. Yet, many businesses still favor HDDs due to their lower cost. At the start of 2024, a 1TB NVMe PCIe 5 SSD cost around $150 – the same price as an 8TB HDD.

With the growing demand for storage-driven by explosive data growth and backup best practices (3-2-1, 4-3-2, 3-2-1-1-0) – choosing the right media is critical. Many experts argue that hard drives remain more reliable and predictable, while SSDs, despite improvements, can still experience unexpected failures.

But HDDs and SSDs aren’t the only options. Tape storage remains in play, offering a much cheaper alternative to HDDs for long-term archival. However, HDDs are far superior for short-term storage and incremental backups. Speed is also a factor – HDDs provide faster data access compared to tape, where retrieving data can take minutes due to loading and rewinding times. Restoring a large file system from 30 tapes could add up to two hours of delay, whereas HDDs work instantly.

Network Throughput: The Silent Bottleneck

Backup performance isn’t just about storage; network speed plays a huge role, too. If backups run multiple times a day, high bandwidth is essential. But if backups occur less frequently – say, once a week or only after hours – the network load is lower. To pinpoint bottlenecks, companies should analyze their network’s data transfer speed. A simple formula can help:

Backup Data Size / Backup Window (time allocated for backup without disrupting operations)

For instance, backing up 5TB of data within a six-hour window requires a network capable of transferring 853GB per hour (5,120GB / 6 hours). On a Fast Ethernet (100Base-T) network, transferring 250GB takes about an hour, whereas a Gigabit Ethernet (1000Base-T) network is ten times faster. In this case, Fast Ethernet won’t cut it.

To improve network performance, businesses can:

• Extend the backup window
• Use dedicated high-speed networks
• Upgrade to Gigabit Ethernet
• Optimize data through compression and deduplication

Slimming Down Data: Deduplication & Compression

With data storage costs on the rise, companies are turning to compression and deduplication to reduce backup sizes.

Compression comes in two types:

• Lossy: Removes unnecessary data (e.g., reducing image quality slightly)
• Lossless: Keeps all data intact, essential for text files, executables, and spreadsheets

For example, a 50MB file with a 2:1 compression ratio shrinks to 25MB. However, compression can reduce network throughput while processing data. While a small quality loss in compressed images may go unnoticed, it matters for high-resolution projects.

Deduplication, on the other hand, prevents redundant data from being stored multiple times. It scans, divides data into blocks, and saves only unique ones.

A key metric here is the deduplication factor, which is often misunderstood. If a solution advertises a 10:1 deduplication factor, it doesn’t mean twice the reduction compared to 20:1. Instead, the percentage of data saved follows this formula:

% Data Reduction = 1 – (1/DD) x 100%

• 10:1 Deduplication: 90% data reduction
• 20:1 Deduplication: 95% data reduction

The difference between a 10:1 and 20:1 factor is only 5%, not double the savings as some assume.

Performance Optimization: It’s All About Balance

Reducing backup sizes is a smart move, but it must align with broader data protection strategies. Think of it like fuel efficiency in a car: a vehicle might have great mileage, but if the driver has bad habits – like underinflated tires or carrying unnecessary weight – it will still waste fuel.

The same principle applies to backup performance. Every component – from media type and network speed to compression and deduplication – affects the overall efficiency. The key is balancing cost, speed, and reliability to ensure optimal data protection.

By understanding these details, businesses can make smarter backup decisions—without sacrificing performance or security.
