What Ransomware Actually Does to Your Backups (And How to Stop It)
Short answer: Modern ransomware targets backups first, because working backups remove any reason to pay. Protect them with the 3-2-1 rule (three copies, two storage types, one off-site), keep one copy disconnected from your main network with separate credentials, and use immutable storage that cannot be altered or deleted. Do not pay a ransom before exploring every other option.
Ransomware doesn’t just lock up your computers anymore. Modern attacks are built to find and destroy your backups first, specifically because backups are what would let you recover without paying. If your backup strategy was built assuming ransomware would never touch it, it’s time to rethink that assumption.
Why Ransomware Targets Backups First
Attackers know that a business with working backups has no reason to pay a ransom. That’s exactly why modern ransomware actively searches for backup files and connected backup drives, and encrypts or deletes them before locking the rest of your systems. A backup sitting on the same network, or accessible with the same credentials as everything else, is often the first thing to go.
The scariest calls I get are not about ransomware locking up a computer. They are the ones where the backup that was supposed to save them turns out to be encrypted too.

What Makes a Backup Actually Ransomware-Resistant
Ransomware-resistant backups aren’t about a single tool, they’re about how the whole system is structured: keeping at least one copy disconnected from your main network, using separate credentials so a compromised login can’t reach the backup, and using immutable storage that can’t be altered or deleted even by an attacker with admin access.
What to Do If Ransomware Already Hit Your Backups
If your backups are already encrypted or missing, don’t pay the ransom before exploring every other option, decryption isn’t guaranteed even after payment. Isolate affected systems immediately, and get an experienced team involved to assess what, if anything, is actually recoverable before making any other decisions.
How The Computer Guyz Approaches This
We design backup systems assuming an attacker might eventually get in, not just planning for hardware failure. Our data backup and recovery includes offsite, access-separated backup copies specifically built to survive a ransomware event.

Frequently Asked Questions
Can ransomware actually reach and destroy backup files?
Yes, modern ransomware actively searches for connected backup drives and network storage and will encrypt or delete them along with everything else if they are reachable.
What does the 3-2-1 backup rule mean?
It means keeping three copies of your data, on two different types of storage, with at least one copy kept offsite or disconnected from your main network.
Should I pay a ransom if my backups are already affected?
Paying does not guarantee your data will actually be restored, and it should generally be a last resort explored only after confirming there is no recoverable backup.
What makes a backup immutable?
An immutable backup cannot be changed, encrypted, or deleted once it is written, even by someone with administrator access, which protects it from ransomware that targets backup files directly.
How is a ransomware-resistant backup different from a regular backup?
A regular backup focuses on recovering from accidental loss or hardware failure. A ransomware-resistant backup is specifically structured so an attacker inside your network cannot reach or destroy it.
