The 4 Most Expensive Backup Assumptions Businesses Make
Ransomware attackers don’t go after your files first. They go after your backups. Veeam’s 2025 Ransomware Trends Report found that 89% of organizations hit by ransomware had their backup repositories specifically targeted, and attackers modified or deleted an average of 34% of those repositories during the attack.
That’s the problem with backup assumptions. They hold up fine until someone tests them on purpose, whether that someone is you or an attacker.
Here are four assumptions that cost businesses the most when they turn out to be wrong.
Assumption #1: “We’re backed up”
Having a backup that’s never been restored is like keeping a spare tire you’ve never actually pulled out of the trunk. You assume it’s inflated. You assume it fits. You find out otherwise on the side of the road.
Most business owners have seen the green checkmarks and the completion emails. Far fewer can say when they last tested an actual restore, how long it took, or whether every critical file and application made it into that backup at all.
A backup only proves its value the moment it restores something. Until then, it’s a theory.
Assumption #2: “We’d know if something was wrong”
Monitoring tools are excellent at detecting problems. Detection isn’t the same thing as protection, and conflating the two is where a lot of businesses get caught.
A weather alert tells you a storm is coming. It doesn’t board up your windows. The alert only has value if someone acts on it fast, with a plan already in place. A dashboard that flags an issue at 2 a.m. only helps if someone’s watching it and knows exactly what to do next.
Assumption #3: “Our team knows what to do”
Every team looks prepared until the outage hits on a Friday afternoon and nobody can agree on who’s in charge.
Veeam’s research found something telling here: 69% of ransomware victims believed they were well prepared before an attack. After the attack, that confidence dropped by more than 20 points. And while 98% of organizations had some kind of ransomware playbook, fewer than half of those plans actually included backup verification steps or a defined chain of command.
A plan that exists on paper but has never been walked through in practice isn’t much different from no plan at all.
Assumption #4: “It won’t happen to us”
Threat intelligence firm Cyble found that U.S. ransomware incidents jumped 149% year over year in just the first five weeks of 2025 compared to the same period the year before. Mid-sized companies, the 11-to-1,000-employee range where most Houston and DFW businesses fall, made up 64% of victims, largely because their defenses tend to be less mature than a large enterprise’s.
Most disruptions aren’t the dramatic kind. An employee clicks a bad link, a drive fails, the power goes out mid-backup. The question isn’t whether something unexpected happens. It’s whether the backup you’re counting on actually holds up when it does.
Test the assumption before it costs you
The businesses that recover fastest aren’t the ones lucky enough to avoid an incident. They’re the ones who tested their assumptions in advance, with a real restore, not a checkmark.
