In sintesi

Disaster recovery (DR) planning ensures business continuity. You define RPO (how much data loss is acceptable?) and RTO (how long can systems be down?), then build infrastructure and processes to meet those targets. Salary: junior DR analysts $65-95k USD; senior architects $120-180k. Learning curve: 4-6 months for operational skills, 2+ years for architecture. Adjacent to cybersecurity, operations, and cloud infrastructure.

Cos'è Disaster Recovery Planning

Disaster recovery is the process of preparing for and recovering from catastrophic failures: natural disasters, cyberattacks, ransomware, data center outages, human error. A DR plan specifies how to restore critical systems and data with minimal downtime and data loss. Core components: RPO/RTO targets, backup/replication infrastructure, failover procedures, runbooks (step-by-step recovery guides), communication plans, and regular testing.

❓ Domande frequenti

What's the difference between RTO and RPO?
RTO = Recovery Time Objective (how long systems can be down). RPO = Recovery Point Objective (how much data loss is acceptable). Example: RTO = 4 hours, RPO = 1 hour means you'll be down max 4 hours and lose at most 1 hour of data.
How do I design a DR plan?
1) Map critical systems. 2) Define RTO/RPO for each. 3) Calculate cost of downtime. 4) Design recovery strategy (backup, replication, failover, etc.). 5) Build infrastructure. 6) Test regularly. 7) Document and train.
What's the difference between backup and replication?
Backup = snapshot of data saved to disk/cloud. Replication = continuous syncing of data to remote location. Backup is cheaper and simpler. Replication meets stricter RPOs but costs more.
How often should I test my DR plan?
Annually minimum. Quarterly is better. Testing reveals issues: outdated documentation, forgotten passwords, missing dependencies. A DR plan that hasn't been tested will fail when you need it.
What should a runbook include?
Step-by-step instructions for recovery. Concrete steps (not vague), with specific commands, IP addresses, and passwords (in a vault). Include escalation contacts, communication templates, and a timeline. A runbook written during a crisis = chaos.
