Attackers often spend days or weeks inside a network before triggering an attack, specifically targeting recovery points to maximize leverage. If backup storage sits on the same network or uses the same admin credentials as production, it’s already a target.<\/p>\n

The answer is immutable backup storage: a layer where data, once written, can’t be modified or deleted \u2014 not by ransomware, not by a compromised admin, not by anyone \u2014 until a set retention period expires. But not all immutability is equal. Policy-based immutability can be reconfigured by an admin with the right credentials. True immutability is enforced at the hardware and OS level, so even a fully compromised environment can’t touch backup data.<\/p>\n

This guide covers seven on-premises immutable backup solutions and what each delivers when your threat model includes a fully compromised admin account.<\/p>\n

Four dimensions matter most:<\/b><\/p>\n
