World Backup Day at 15: Why “having backups” still isn’t enough

Modern data lives everywhere, threats are routine, and untested backups create false confidence

Key takeaways

• Backups fail most often at restore time. If you haven’t tested restores, you don’t actually know whether your business can recover.
• Critical data now lives beyond traditional backup scope. Multiple complex environments can all hold data that determines whether systems — or entire operations — come back online.
• Backup proximity creates real risk. Backups that live too close to production systems are exposed to the same ransomware, insider threats, and configuration failures they’re supposed to protect against.

Fifteen years ago, a Redditor proposed a “Back-Up Day” to a community full of tech enthusiasts. The idea was simple: set aside one day a year to remind everyone to back up their data. The first World Backup Day was March 31, 2011, and it was a big Reddit-based event. We all liked it so much that we’ve been marking the day ever since.

A lot has changed since 2011. In the backup space, the technology has matured — better software, purpose-built appliances and more storage options. The bigger shift is in how data gets lost. Digital files have always been subject to human error and hardware failures. That hasn’t changed, though you now have higher risk associated with cloud configurations and web application security. It’s the modern threat actor that has really changed the landscape. Ransomware groups, malicious insiders and supply chain compromises are now routine risks to business data. The data itself has moved to places beyond the reach of traditional backup.

The data itself has also changed. Your critical business information isn’t just sitting on a server in the back room. It could be in a SaaS environment like Microsoft 365, an identity infrastructure like Entra ID or in a shop floor legacy device that is critical to production. Lose the wrong piece of data in these environments, and you could lose access to an entire system — or the ability to recover one.

Here's the uncomfortable truth that keeps showing up in the research: most companies don't regularly test their backup restore processes — and a backup you've never restored is a hope, not a plan. Even if you have an automated backup that completes successfully each day, you still don’t know if you have a backup that can restore the business to the state it needs to operate.

World Backup Day is a good reminder to get back to the basics on backup. Start with a few basic (but important) questions:

Are you backing up everything that matters? That includes SaaS application data, cloud-based identity configurations like Entra ID, operational technology (OT) and other industrial controller settings, and anything else required for business continuity.

Are your backups protected? If your backup lives in the same environment as your production data, a single incident could take both out. Is it possible for an attacker or a failure to move laterally between the two?

Have you tested a restore? CIS Control 11 recommends testing quarterly at minimum. See our post on Reddit for a quick review of this and the five Safeguards that can help you eliminate gaps in your backup system.

World Backup Day is a good time to take an honest look at what you’re protecting and what you might be missing. Backups that haven't been tested, live too close to the systems they protect or don't cover critical cloud and identity data can create a false sense of security. When something goes wrong, that gap is exposed very quickly.
