Ransomware in 2026: Backup Strategies That Actually Work
2 April 2026 · 6 min read
Backups are now the first target
Modern ransomware operators spend days or weeks inside a network before encrypting anything. Their first objective is finding and destroying your backups — because a business that can restore won't pay. If your backup server is joined to the same domain, reachable from the same network, and protected by the same credentials, it will be encrypted alongside everything else.
The 3-2-1-1-0 rule
The modern standard: keep 3 copies of your data, on 2 different media types, with 1 copy off-site, 1 copy immutable or offline, and 0 errors verified by automated restore testing. The two additions that matter most are immutability — storage that physically cannot be altered or deleted during a retention window — and verified restores.
Untested backups are not backups
More than half the recovery failures we see come not from missing backups but from backups that were silently failing for months, or restore processes that take days when the business assumed hours. A disaster recovery plan needs measured RTO and RPO numbers, and a drill calendar to prove them.
What we recommend
Immutable cloud backup for critical systems, isolated from production credentials; quarterly restore drills with documented timings; and an incident response runbook that doesn't assume your file server, email or documentation will be available when you need them. Recovery readiness is a discipline, not a product.
