More mistakes(2)
Handle with care. Do not use as a verb (avoid saying 'to disaster recovery'). It is a noun phrase. Also, do not confuse with 'backup' — disaster recovery is the entire plan and process, not just data backup.
- ✕Our disaster recovery is just daily backups.✓Our disaster recovery plan includes daily backups, redundant servers, and tested failover procedures.
Disaster recovery is broader than backups alone. It encompasses strategy, infrastructure, procedures, and testing.
- ✕We will disaster recovery if something goes wrong.✓We will follow our disaster recovery procedures if something goes wrong.
Do not use disaster recovery as a verb. Instead, say 'follow the disaster recovery procedures' or 'activate the disaster recovery plan.'

Questions(8)
- What do RTO and RPO mean in disaster recovery?
- RTO (recovery time objective) is how fast systems must be back. RPO (recovery point objective) is how much data you can afford to lose, measured in time. “RPO of 15 minutes” means at most 15 minutes of data loss.
- What is the difference between backup and disaster recovery?
- A backup is a copy of data. Disaster recovery is the full plan to restore service: backups, standby systems, runbooks, and regular tests that prove it works.
- What does disaster recovery mean in IT?
- Disaster recovery is the plan and process for restoring systems and data after a major failure, such as a region outage, a cyberattack or accidental deletion, so the business can keep running.
- What is the difference between RTO and RPO?
- RTO is how long you can be down before it becomes unacceptable. RPO is how much data, measured in time, you can afford to lose. RTO of 1 hour and RPO of 5 minutes means you recover within an hour and lose at most 5 minutes of data.
- What is the difference between disaster recovery and backup?
- A backup is a copy of your data. Disaster recovery is the full plan to get systems running again: restoring data, rebuilding infrastructure, switching traffic and communicating. A backup is one part of DR.
- What is the difference between disaster recovery and high availability?
- High availability prevents downtime with redundancy, for example several servers behind a load balancer. Disaster recovery restores service after a failure that high availability could not absorb, such as losing a whole region.
- What is a DR drill?
- A DR drill is a planned test where the team practices the recovery plan, for example by failing over to a backup region. It shows whether the documented steps really work before a real disaster.
- How do I talk about disaster recovery in English at work?
- Useful phrases are invoke the DR plan, fail over to the secondary region, restore from backup and run a DR drill. With customers, say major outage instead of disaster.
