A database administrator is reviewing the disaster recovery plan for a critical e-commerce database. The plan outlines a process where, after a regional outage, a backup database is brought online in a different data center. This backup database is kept updated by restoring daily full backups and applying hourly transaction log backups. The total time estimated to fully restore and make the database available is 6 hours. What is the Recovery Time Objective (RTO) for this scenario?
- A1 hour
- BDaily
- C6 hours
- D24 hours
Show answer & explanationAnswer & explanation
Correct answer: C. 6 hours
The Recovery Time Objective (RTO) is the maximum acceptable downtime after a disaster. The scenario explicitly states that the total time estimated to fully restore and make the database available is 6 hours, which directly defines the RTO.
Why the other options are wrong
- A. This might relate to the RPO (hourly log backups) but not the RTO.
- B. This is a frequency, not a time objective for recovery.
- D. This might relate to the frequency of full backups, but not the RTO.
Recovery Time Objective (RTO)
The Recovery Time Objective (RTO) is the maximum acceptable duration of time that a computer system, application, or network can be down after a disaster or failure. It defines how quickly systems must be restored.
- Maximum acceptable downtime.
- Measures the speed of system restoration.
- A crucial metric in disaster recovery planning.
Memory trick: RTO: 'Time to Operate' again. RPO: 'Point of Data' lost.
