Understanding and Defining Recovery Point Objective (RPO) in DR planning

Understanding recovery point objective (RPO) in DR planning

What does RPO stand for?

Recovery Point Objective (RPO) is the maximum amount of data your business can afford to lose due to an unexpected event like a system failure or disaster. It is measured in time — specifically, the interval between your last successful data backup and the disruptive event.

In simpler terms, RPO defines:

  • The maximum amount of data your organization is willing to lose. For instance, if losing more than 1 hour of data affects your business, your RPO should reflect that.
  • How often to schedule your backups to minimize data loss.
  • The time it takes to resume operations after a disruption.

It is crucial to have a comprehensive business continuity plan (BCP) in place to ensure your recovery strategies and technology are effective if a catastrophe occurs. A well-developed BCP will establish clear guidelines for the maximum allowable Recovery Time Objective (RTO) and help minimize data loss during disruptions.

Here’s an example of RPO

Let’s say your business experiences a disaster, and the last backup was 8 hours ago. If your RPO is 10 hours, your backup falls within the acceptable limit. However, if your previous backup was 12 hours ago, this would exceed your data resilience threshold and impact operations.

What is the difference between RPO and RTO?

RPO focuses on how much data a business can afford to lose. RTO determines how quickly systems operation systems need to be restored after a disruption and establishes the maximum acceptable downtime before your business becomes less efficient and starts to lose revenue.

Why is recovery point objective important in disaster recovery?

A sound RPO helps maintain maintain the integrity of your disaster recovery plan in the following ways:

  • Enhancing the effectiveness of the BCP by ensuring that data continuity strategies align with organizational needs.
  • Protecting essential applications and systems that the business requires to operate.
  • Assisting in determining your Service-Level Agreement (SLA) during disruption, ensuring customers and partners are supported.

How do you calculate recovery point objective?

Follow these steps to calculate your business’s optimal RPO.

Identify data loss tolerance

Decide how much data your business can afford to lose without severe disruptions to daily operations. For example, can you tolerate losing an hour’s worth of transactions, or is every second critical?

Assess the cost of downtime

Calculate how an unplanned system downtime would affect your business’s operations and finances. Consider factors like how much income you lose per hour of downtime, effects on productivity, and potential loss of trust from your clients.

Prioritize with a tier system

Create a comprehensive list of all systems and applications critical to your business and organize them into tiers based on their importance and acceptable data loss thresholds. For instance:

  • Tier 1/Gold (0–1 hour): This tier includes mission-critical business operations that cannot afford to lose more than an hour of data, such as banking transactions, CRM systems, patient records, etc.
  • Tier 2/Silver (1–4 hours): This tier represents semi-critical business units that can afford data loss of up to 4 hours, such as file servers and customer chat logs.
  • Tier 3/Bronze (4–12 hours): This tier includes businesses that cannot afford to lose more than 12 hours’ worth of data, such as sales and marketing data.
  • Tier 4/Copper (13–24 hours): Businesses that deal with semi-critical information requiring an RPO of at least 24 hours fall under this tier. Examples include human resource data (HR) and purchase departments.
