What does RPO stand for?
RPO stands for Recovery Point Objective. The maximum acceptable data loss, measured in time. An RPO of 4 hours means backups must run at least every 4 hours.
RPO is the point in time to which data must be restored after an outage. In practice it states how much recent data the business can afford to lose, measured in time. It drives how often you back up or replicate: an RPO of four hours means a copy at least every four hours. The smaller the RPO, the more the protection costs.
RPO in practice: an example
An order system has an RPO of 15 minutes. Nightly backups cannot meet it, because a failure at 17:00 would lose a full day of orders. The team adds transaction-log shipping every 10 minutes, so the worst case is 10 minutes of lost orders, inside the objective.
What RPO is confused with
RPO vs RTO: what is the difference?
RPO looks backwards from the failure: how much data is lost. RTO looks forwards: how long until the service is running again. What RTO stands for
Which exams cover RPO?
RPO is on the official CompTIA acronym list for two of the four exams covered here.
- Security+ SY0-801: 3.4 (Security Architecture).
- Network+ N10-009: 3.0 (Network Operations).
Each number is a CompTIA exam objective and the name in brackets is its domain. The exam puts the term in a scenario; it does not ask you to recite the expansion.
Check yourself: two practice questions
Written by CertSprint for this page. They are not taken from any exam.
1. A database is backed up once a day at midnight. It fails at 18:00. How much data is lost in the worst case, and which objective does that measure against?
- 18 hours, RPO
- 18 hours, RTO
- 6 hours, RPO
- 24 hours, MTBF
Show the answer
A. 18 hours, RPO. Everything since the last backup is lost: 18 hours. Data loss measured in time is compared with the RPO.
2. The business states it can lose at most one hour of transactions. Which design meets that?
- Weekly full backups
- Replication or log backups at least every hour
- A faster CPU
- A longer password policy
Show the answer
B. Replication or log backups at least every hour. The copy interval must not exceed the RPO. Weekly backups could lose up to a week.
