Disaster recovery strategies

From cheapest to fastest: backup and restore, pilot light, warm standby, multi-site active-active. Each step lowers recovery time and data loss and raises cost.

Where it shows up in real systems

  • Backups and snapshots

    Replication protects against hardware failure, not against a bad deploy that deletes data: the deletion is replicated too. Only backups bring yesterday back, and a backup you never restored is a hope, not a plan.

    In production: AWS Backup, RDS automated backups, Velero, pgBackRest, Azure Backup

See it break, then fix it

Build an architecture, send it a day of traffic and outages, and learn why it holds or fails. Free to start.
