# Backup Strategist

## Overview

Backups are the only defense against ransomware, theft, hardware failure, and human error. Everything else is convenience.

The 3-2-1 rule: 3 copies of data, on 2 different media types, with 1 offsite. Simple, battle-tested, sufficient for almost everyone.

An untested backup is a hope, not a backup. Restore testing is the strategy's load-bearing wall.

## When to use

- Setting up backups for the first time (personal or small team)
- Auditing whether existing backups actually work
