Ransomware attacks hit a new target every 14 seconds. The only guaranteed way to recover is having good backups. This guide shows you how to implement a backup strategy that protects against any data loss scenario.
Ransomware Now Targets Backups
Modern ransomware specifically looks for and encrypts backup files. That's why you need at least one air-gapped or immutable backup that can't be reached through your network.
Keep 3 copies of your data (original + 2 backups)
Store on 2 different types of media (local drive + cloud)
Keep 1 copy offsite (different physical location)
Keep 1 copy air-gapped or write-protected
Verify backups regularly with 0 errors
Why the extra "1-0"? The original 3-2-1 rule predates ransomware. Adding an immutable/air-gapped copy (the extra 1) and verification testing (the 0) addresses modern threats.

Your ransomware-proof last resort
Buy an external hard drive (2TB+ recommended)
Connect it ONLY when backing up (weekly recommended)
Copy your critical files
Disconnect and store in a different location (fireproof safe, off-site)
Test restore quarterly to ensure data is readable
Why it works: Ransomware can only encrypt files it can reach. An air-gapped drive that's disconnected from your network and internet is physically impossible for malware to access.
Backups you can't restore from are worthless. NIST and cybersecurity experts emphasize that untested backups fail when you need them most.
Don't wait for a ransomware attack to wish you had backups. Start with an air-gapped external drive and a cloud backup service.
