Why Backups Matter
- Cyberattacks: ransomware can lock or destroy files.
- Human error: accidental deletions happen every day.
- Hardware failure: drives, servers, and NAS eventually fail.
What a Solid DR Plan Includes
- 3-2-1 rule: 3 copies, 2 media types, 1 off-site.
- Automated schedules: daily or hourly snapshots.
- Immutable backups: protection from ransomware.
- Runbooks: step-by-step restore procedures and RTO/RPO targets.
Pro tip: backups are only as good as your last successful restore. Test recovery quarterly.
