Backup Strategy

SkillFiles & storage

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).

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)

Required Inputs

Ask for these if not provided:

  • Devices & OS — computers, phones, and what platform each is
  • What matters most — photos, documents, work files, and roughly how much data
  • Current backups — what (if anything) exists now, and whether it's tested
  • Budget & comfort — external drives, cloud services, willingness to pay/automate
  • Threats of concern — device loss/theft, hardware failure, ransomware, accidental deletion

Framework: 3-2-1, Automated, Tested

  1. Apply 3-2-1. Three copies, two different media (e.g. local drive + cloud), one off-site — so no single event (fire, theft, ransomware) takes everything.
  2. Prioritize the irreplaceable. Photos, personal documents, and unique work first; apps and media you can re-download come later.
  3. Automate it. Scheduled/continuous backup beats manual — the ones you have to remember are the ones that lapse.
  4. Protect the backups themselves. Keep at least one copy offline or versioned, so ransomware or a bad sync-delete can't wipe every copy at once.
  5. Test the restore. Recover a real file (and ideally a full-system test once). An untested backup fails exactly when it matters.

Output Format

Backup plan: [devices] · [key data] · [budget]

3-2-1 for you

  • Copy 1 (primary): [device].
  • Copy 2 (local): [external drive / NAS] — automated [how].
  • Copy 3 (off-site): [cloud/off-site] — automated [how].

Back up first: [photos, documents, unique work]. Later: [re-downloadable]. Automate: [schedule/tool per device]. Protect backups: [versioning + one offline copy] against ransomware/sync-deletes. Test: restore [a file] now; full-restore test [once].

Quality Checks

  • Plan follows 3-2-1 (three copies, two media, one off-site)
  • Prioritizes irreplaceable data first
  • Backups are automated, not manual/remembered
  • Includes a restore test, not just a backup
  • Protects backups from ransomware/sync-delete (offline/versioned copy)
  • Tailored to the person's devices and budget

Anti-Patterns

  • A single copy on one drive — no redundancy.
  • Manual backups that quietly lapse.
  • Never testing a restore — discovering it's broken during a crisis.
  • All copies online/connected so ransomware or a sync-delete hits them all.
  • Backing up everything equally and burying the irreplaceable stuff.

Example Trigger Phrases

  • "How should I back up my photos and files properly?"
  • "Set me up a backup system for my laptop and phone."
  • "I don't want to lose my photos if my phone dies — what do I do?"
  • "Is my current backup actually safe from ransomware?"
  • "What's the 3-2-1 backup rule and how do I set it up?"
