A data disaster can happen at any time. Do you think your business can survive losing a day, a week, or even a month's worth of data?
When it comes to data backup and disaster recovery, determining your recovery point objective (RPO) is critical. RPO is the metric you set for the amount of data your business can afford to lose in a data disaster.
Your RPO helps decide how often you need to back up your data systems and the necessary infrastructure to sustain your backup plan. In most cases, a disaster recovery as a service (DRaaS) solution from a managed service provider can help you meet your recovery point objective goals.
RPO is a crucial business metric that every organization should track. When combined with a recovery time objective (RTO), RPO provides a prioritized list of all systems, applications, and data to protect.
Recovery point objective (RPO) is the maximum amount of data loss permissible for a specific application system or IT function to recover without experiencing business failure. RPOs go back to a time when your data was in good condition, usually from a recent save or backup.
A business’ loss tolerance, or how much data it can lose without suffering severe damage, is connected to RPO and outlined in its business continuity strategy. As RPO refers to the last period when the company's data was preserved in a viable state, it also specifies processes for disaster recovery planning, including the appropriate backup interval. For instance, RPOs with a duration of 60 minutes need a continuous backup every 60 minutes.
RPO is typically combined with recovery time objective (RTO), or the estimated time it takes for a company's activities to resume regular operations following a data disaster. These measurements support company’s plan for disaster recovery, mainly to stay operational during and after a crisis. Disaster recovery solutions that use RTO and RPO often guarantee that vital information is properly copied, preserved, and quickly accessible when needed.
You can define different RPO for different parts of your business. For example, platforms such as email servers, ERP systems, CRM tools, and HRMS can have various RPO and RTO values.
A single unplanned outage can be catastrophic for your business. The risk of data loss has significant repercussions for businesses. As business operations are crucial to any organization's existence, many have strict standards to maintain optimal security for valuable data assets.
A recovery point objective is crucial because it can massively impact how an organization operates and costs money. For example, if you set an RPO of 6 hours across your systems and encounter a crippling digital event, you will most likely lose 6 hours of data since the last, most recent point from which you can recover stored data is 6 hours ago.
RPO establishes:
What is Zero RPO? Zero RPO denotes unacceptable data loss. Data designated as Zero RPO is data your organization cannot lose even for a second without grave repercussions. Maintaining Zero RPO requires continuous data protection and replication to ensure data is never lost. Digital medical data at a hospital or financial transactions at a bank are two examples of potential Zero RPO data.
Electronic information and software propel business development. Adopting a disaster recovery strategy protects companies from data loss and its damaging effects. RPOs and RTOs are critical components of a superior data protection and disaster recovery plan.
Adopting and executing appropriate RPOs benefit data protection and disaster recovery strategies and other business processes in a variety of ways:
RPOs specify the amount of time that can elapse before data loss’ magnitude exceeds the permissible limit under a business continuity plan (BCP). Loss tolerance varies by business process and workload, influencing the associated RPO for that workload.
High-priority applications often have stricter RPOs that require more frequent backups. In such cases, the IT team needs to prepare backup solutions to meet certain RPOs, such as a mix of snapshots and replication (also known as near-continuous data protection (CDP)).
When RPO is near zero, IT merges failover services with continuous replication or a continuous data protection system to achieve almost 100% application and data availability.
Setting an appropriate data backup frequency ensures continuous backup within the loss tolerance limit. System administrators can automatically define an RPO as a policy option within backup or storage software and cloud services.
RPOs are often chosen depending on data update frequency. This guarantees that, in the event of a service disruption, all resumed operations have the most recent version of the data. For example, regularly changing files requires a short (no more than a few minutes) RPO. This implies that companies can resume operations with minimal data loss after a disruption.
Once established, RPOs should become the pillars of your business continuity strategy, acting as targets for the operations they define. Your program should outline different RPOsfor different business units. A mission-critical data activity, such as financial transactions, requires a shorter RPO than less regularly updated files, such as employee information.
The following are some sample tiers you should consider when determining the appropriate RPOs for your organizational units:
While RTO and RPO are linked in many ways, RPOs relate specifically to the retained data. There’s an RPO for everything, whether it's a client database, financial transactions, or a list of staff birthdays. Businesses with effective disaster recovery (DR) plans incorporate RPOs in their approach and planning.
Here’s an example of recovery point objectives in action.
A big global e-commerce website with several servers for various tasks develops recovery point targets depending on a server’s unique usage and the data it maintains. As it operates globally and sells 24 hours a day, key parts of its data management system require continuous replication rather than daily or weekly backups. Executives can highlight the following recovery point objectives:
If a massive data incident happens, the e-commerce company's critical information, such as evidence of things sold, reverts to the most up-to-date information since it’s recorded every 60 seconds.
Slightly less critical information, such as a customer product review published shortly before the data loss, wouldn't be on the site after the restoration. Still, those from the previous day will remain because IT set the RPO to 24 hours.
The recovery point objective is closely linked to the recovery time objective. It’s the maximum amount of time that business computing resources and applications can remain inoperative following a malfunction or disaster. These metrics can help guide selecting suitable data backup strategies. They also provide a base for discovering and evaluating viable solutions that will allow a company to resume business operations within a timeframe close to RPO and RTO.

The two techniques enable business continuity planning (BCP) and a DR plan. Although interrelated, understanding the difference between RTO and RPO helps a company’s bottom line.
RPO governs loss tolerance and the amount of data a business can afford to lose. It's a planning goal that specifies how frequently IT teams should back up data to enable recovery.
A company supports RPOs by implementing a DR strategy that backs up data at appropriate intervals, ensuring that data loss never exceeds the business's predefined loss tolerance.
RTO comes into the equation following a “loss event”. It assists a company in assessing how soon it can recover from a data loss due to a malfunction, natural disaster, or misconduct. RTO further explains, "How long should it take to restore normal operations after a business process disruption?". RPO and RTO work together, with RPO ensuring a company has the proper data backup procedures and RTO guaranteeing that backups recover quickly.
RPOs and RTOs vary by application and data importance. Near-zero RPO and RTO are incredibly expensive since the only way to avoid zero data loss and 100% uptime is continuous data replication in virtual failover environments.
Due to the cost of attaining a near-zero RPO and selecting the right data and systems, the cost of achieving adequate RPO and RTO depends on the purpose, risk, and expenses. RTO focuses on systems and applications, meaning it mainly computes time constraints on service downtime rather than data recovery.
This is another way of understanding the RTO vs. RPO debate: RPO concerns how much data a business loses following a failure. RTO addresses poor user experience and unhappy consumers, whereas RPO addresses catastrophic situations like losing hundreds of thousands of dollars in client transactions.
There are several factors to consider when developing an RPO strategy, including:
How you want recovery to function dictates the frequency with which you back up key data, apps, and systems. There are two key disaster recovery objectives when planning a DR strategy: RTO and RPO. Consider the following five steps when calculating recovery point objectives for your company or industry.
You can control the periodicity of updating files by setting an RPO goal. This makes your most recent data accessible. For example, you have digital copies and operations that update every 30 minutes. Establishing an RPO for every 30-40 minutes ensures you consistently access the most up-to-date data with little information loss.
In contrast, if your business defined an RPO for a weekly backup save every Saturday night, a technical failure that occurs on Saturday afternoon would result in the loss of a whole week's worth of data since the system backup had not yet taken place that day. You can modify your RPO, so try regularly assessing your file update periods to see whether the RPO needs changing.
Recovery point objectives complement your business continuity plan goals. So carefully evaluate each aspect to define RPOs with different time allotments for every business segment, depending on the data they contain and how crucial they are if data loss occurs.
For example, a national bank's financial transactions and necessary data operations are critical and need significantly shorter RPO times than human resource documents with personnel records that are updated less regularly and can withstand a longer RPO time.
While each company's RPO requirements could be unique, you can use industry standards to guide you when establishing RPOs for organizational units at your business. Most business transactions fit within general industry RPO time parameters. However, depending on your company’s size or its objective, you can employ weekly data settings.
For example, a global air carrier with employees spread across hundreds of locations will most likely update its HR records frequently. In contrast, a single office insurance provider with 30 employees can choose to update personnel files once a week because they’re less prone to change than the airline's HR records.
Develop RPOs after examining all risks for each aspect of your data management and having them accepted by executives for IT or partner deployment. Document the process thoroughly and keep records to refer to and use as a benchmark for reviewing or adjusting an RPO.
Your recovery point objectives can evolve as your company develops or your business continuity strategies change. Consider introducing a systematic and frequent analysis and assessing how well your current RPO settings perform and whether they need to be adjusted.
Even though it comes last, this is a vital step. If you have a data loss event or system failure, an ad hoc evaluation and in-depth examination of how your RPO and RTO performed can provide valuable insights into your entire data management system.
Failover is switching between your primary and backup systems during an outage or scheduled system downtime. It’s essential to consider your company's RPOs when selecting a failover solution to avoid losing excessive data while moving to a backup server. For instance, a 10-minute RPO indicates that your failover solution must respond within that timeframe to ensure that you don't lose more than 10 minutes of data.
Failover methods can include:
Planning for disaster recovery can be difficult and time-consuming. If you don't have the right tools or experience, it's easy to miss things. But with a good IT team and regular training in place, you can avoid some of the mistakes that could cost your company dearly in lost revenue.
