backup-strategy

Set up a backup system that actually protects your photos, files, and devices — built on the 3-2-1 rule and, crucially, tested so it works when you need it. Use when asked how to back up my data, set up backups, protect my photos/files, or what's a good backup strategy. Produces a 3-2-1 plan tailored to your devices and data, specific what-to-back-up priorities, an automation setup so it happens without you, a restore-test step, and protection against the failure that ruins backups (ransomware/sync-deletes reaching the backup).

# Backup Strategy

Everyone means to back up until the drive dies or the phone is lost. This builds a real system on the 3-2-1 rule — three copies, two media, one off-site — sized to your actual data and devices, automated so it happens on its own, and (the step everyone skips) *tested* by doing a restore, because an untested backup is just a hope.

## What This Skill Produces

- **A 3-2-1 plan** — three copies, on two types of media, with one off-site/cloud, mapped to your devices
- **Priorities** — what to back up first (irreplaceable photos/documents) vs. what's re-downloadable
- **Automation** — how to make backups run automatically so they don't depend on remembering
- **A restore test** — actually recovering a file to prove the backup works
- **Resilience** — protecting backups from ransomware/accidental-deletion and sync tools propagating a deletion to every copy (versioning, offline copy)
