Backup Encryption: Why It Matters More This Year

---

If you read our earlier post on how AI changed cybersecurity and what Project Glasswing means for business, you already know the main shift: AI is accelerating both defense and attack cycles. Anthropic announced Project Glasswing on April 7, 2026 as a security initiative to help secure critical software for the AI era, which signals how seriously major technology firms now view AI-driven security pressure. That same pressure is one reason backup encryption matters more this year, not less.

A lot of businesses still think of backups as simple insurance. Copy the files, store them somewhere else, and move on. That mindset is outdated. In 2026, a backup is not just a recovery copy. It is also a sensitive data store, a ransomware target, and a potential liability if it falls into the wrong hands. CISA is explicit on this point: organizations should maintain offline, encrypted backups of critical data and test them regularly.

So why does backup encryption matter more this year?

1. AI has changed the speed of cyber risk

Project Glasswing matters here because it is not just another press release. It is public evidence that frontline security teams expect AI-capable systems to reshape software security and defensive practices right now. Anthropic described Project Glasswing as an effort to secure critical software for the AI era, and its related security material says the initiative is meant to help the industry prepare for the practices needed to stay ahead of cyberattackers.

That has a direct backup implication.

If attackers can move faster, scan wider, and identify weaknesses earlier, then any unencrypted backup becomes a softer target. In older threat models, a criminal might need to break into a live system and spend time hunting for useful data. In newer models, attackers can automate discovery, sort environments faster, and identify exposed copies, sync targets, credential paths, and storage misconfigurations with less friction. Project Glasswing does not say, “attackers now win.” But it does confirm that security has entered a higher-speed era. That makes plain, readable backup data a bigger business risk.

This is where some companies get the logic wrong. They assume redundancy alone solves the problem. It does not.

Redundancy helps you recover availability. Encryption helps protect confidentiality. You need both.

Three copies of your data in three places still fail the test if each copy is readable after theft. A redundant but unencrypted backup is still exposed data.

2. Ransomware groups do not just hit production anymore

This is the second major reason backup encryption matters more now. Modern ransomware actors do not only encrypt live systems. They increasingly look for accessible backups, try to delete them, and in many cases steal data before they trigger encryption. CISA’s ransomware guidance tells organizations to maintain offline, encrypted backups precisely because attackers target backup paths to block recovery. Joint ransomware advisories also continue to describe “double extortion” behavior, where criminals exfiltrate data and then encrypt systems.

That changes the business question from:

“Do we have a backup?”

to:

“Is that backup protected if someone reaches it?”

Those are not the same question.

A business can say yes to backups and still lose badly. Here is the weak version of a backup strategy:

• The backup is always online
• The backup uses the same credentials as production
• Nobody tests restores
• The backup data is unencrypted
• Nobody knows which devices or SaaS accounts are actually covered

That setup gives a false sense of safety. If attackers can reach the backup repository, steal readable data, or encrypt the backup set itself, then the business loses both recovery speed and data privacy at the same time.

Encryption narrows that blast radius. It does not replace isolation, offline copies, or testing. However, it ensures that stolen backup files are not immediately useful.

3. Compliance and breach exposure now hit harder

The third reason is simple and often ignored: backups usually contain your oldest, broadest, and most sensitive business data. That includes customer records, contracts, financial files, employee data, and archived communications. If those copies are not encrypted, the business may be dealing with more than just operational downtime. It may also face breach notification, legal exposure, insurance problems, and trust damage.

HHS guidance on breach notification focuses on breaches of unsecured protected information, while CISA’s small-business guidance tells organizations to encrypt data at rest and in transit and to always encrypt backups. NIST also notes that encryption is a critical line of defense because it can make data captured in a breach effectively unusable to the adversary.

That is the point too many SMBs miss.

An unencrypted backup is not just a technical weakness. It is a liability multiplier.

This matters more in 2026 because businesses keep more data, across more systems, for longer periods. Cloud apps, remote work, endpoint sprawl, and shared storage have all expanded the number of places where business data lives. NIST’s storage guidance notes that evolving storage architecture increases management complexity, which in turn increases the chance of configuration errors and related threats.

More copies plus more complexity equals more chances to expose something that should have been locked down.

Redundancy still matters, but it is not enough

Your instinct to tie this back to redundancy is correct. If you do not have redundant copies, you do not have resilience. NIST’s ransomware-related guidance still supports keeping multiple copies across different media with one copy off-site. CISA also continues to recommend offline copies, encryption, and restore testing.

But redundancy without encryption leaves a major hole.

Think of it this way:

• Redundancy keeps the business running after failure.
• Encryption keeps stolen backup data from turning into a second disaster.

You need redundancy for continuity. You need encryption for containment.

A knowledgeable skeptic would say, “If the backup system itself is compromised, encryption will not save you.” That is partly true. If keys are poorly managed, access controls are weak, and the attacker gains everything, encryption alone will not rescue a bad design. That is exactly why backup encryption should never be sold as a magic fix. It must sit inside a broader recovery design that includes access separation, offline or immutable copies, monitored jobs, tested restores, and documented retention rules.

So the correct claim is not “encryption solves backup risk.”

The correct claim is: unencrypted backups are increasingly indefensible.

What Texas SMBs should do now

If your business wants a practical standard for 2026, use this checklist:

1. Encrypt backup data at rest and in transit.
2. Keep at least one backup copy offline or otherwise isolated.
3. Separate backup credentials from everyday admin access.
4. Test restores on a schedule, not just backup completion alerts.
5. Verify which servers, endpoints, SaaS platforms, and shared drives are actually included.
6. Document retention and recovery targets so leadership knows what “restored” really means.

That is the real takeaway this year. AI-driven security change, ransomware pressure, and rising data liability have all raised the cost of weak backup design. Backup encryption is no longer a nice extra. It is part of basic business-grade recovery.

If you want to know whether your backups are merely present or actually protected, SofTouch Systems can review your current setup and show you where encryption, isolation, and recovery readiness stand today.

Schedule a backup and recovery review with SofTouch Systems and find out whether your current backup system is secure, encrypted, and ready to restore when it counts.
