3-2-1 Backups

Three copies, two media, one off-site — the recovery plan that turns ransomware into an inconvenience.

Core Principles & Analysis

• The 3-2-1 rule: three copies of data, on two different media, one kept off-site.
• Ransomware crews hunt and encrypt online backups first — offline or immutable copies are the counter.
• A backup untested by a restore drill is a hope, not a plan.
