RTO and RPO in Recovery Objectives for IT Success
In: Data Backup & DR

Businesses are well aware that experiencing IT downtime can result in significant costs. Therefore, companies must carefully consider the implications of such downtime and prioritize the maintenance of uninterrupted business operations. In order to achieve this, it is crucial to implement a robust business continuity plan that allows for minimizing or completely avoiding downtime. This way, companies can ensure the resilience of their IT Infrastructure.

When discussing the topic of business downtime, it is common to hear about two important metrics: Recovery Time Objectives (RTO) and Recovery Point Objectives (RPO). It is imperative for every business to possess a comprehensive understanding of RTO and RPO in order to ensure a swift recovery from any potential disasters.

In the following discussion, we will explore how to measure RTO and RPO, the significance of these metrics within a backup business continuity plan, and the process of defining and achieving your business’s RTO and RPO goals.

What is the Recovery Time Objective (RTO)?

The Recovery Time Objective (RTO) is a crucial metric that enables you to calculate the speed at which a system or application must be restored after experiencing downtime, ensuring minimal impact on business operations. Essentially, RTO measures the amount of downtime that can be tolerated.

In the event of unexpected outages, it is possible for one or two systems to fail, resulting in downtime until the issue is resolved. This places you in a situation where you need to determine the timeframe within which the system must be restored to prevent any interruptions in business operations and make Optimize Workplace. This is where RTO comes into play.

Defining RTO involves understanding the tolerance for downtime for each system and application. It is likely that different applications will have varying RTOs. Once you have defined the RTO metric, you are fully equipped to plan for recovery, which includes implementing appropriate recovery strategies and technologies for a successful and swift restoration from downtime.

What is the Recovery Point Objective (RPO)?

The Recovery Point Objective (RPO) is a metric that defines the acceptable level of data loss a business can withstand while still maintaining uninterrupted business operations. To determine the RPO, it is necessary to evaluate the criticality of the data in question. This evaluation will determine whether all data needs to be recovered or if only specific portions are essential. Additionally, there may be less significant data that does not require restoration. Based on these considerations, you can establish the appropriate RPO for your system. The higher the criticality of the data, the lower the value of RPO should be. Determining RPO is an essential aspect of a backup plan as it guides the frequency at which data should be backed up based on its criticality.

Differences between RTO and RPO 

RTO and RPO are important elements associated with backup and disaster recovery plans. Both RTO and RPO are defined as well as measured in units of time. Although RTO and RPO may sound alike, there are some major differences:

Prompt alerts allow you to take proactive measures and minimize downtime by addressing potential problems before they escalate.

Document and communicate the Recovery Plan: 

Create a comprehensive recovery plan that includes step-by-step procedures for restoring systems and data. Ensure that the plan is well-documented, easily accessible, and regularly updated. Communicate the plan to all relevant stakeholders, including IT staff, management, and key personnel, to ensure a coordinated response during a disruption.

Continuous Improvement: 

Regularly review and update your recovery plan based on lessons learned from drills, real incidents, and changes in your business environment. Continuously assess and improve your RTO and RPO targets to align with evolving business needs and technology advancements.

By following these steps and incorporating RTO and RPO considerations into your business continuity and disaster recovery strategy, you can minimize business downtime and maintain operational resilience in the face of disruptions.

How To Achieve RTO And RPO With A Backup And Disaster Recovery Plan?

To achieve your RTO and RPO goals with a Backup and Disaster Recovery Plan, it is important to select a solution that aligns with these objectives. When evaluating backup and disaster recovery solutions, ensure that their Service Level Agreement (SLA) specifies the assured RPO and RTO. This ensures that the chosen solution meets your business recovery objectives.

Backup and Disaster Recovery Solutions offer various functionalities that contribute to achieving your RTO and RPO goals. Let’s explore some important functionalities to look at Why Backup and Recovery Should Be a Priority and how it will assist your business in achieving near-zero RTO and RPO.

Flexible Scheduling Policies

Modern backup and disaster recovery solutions provide flexible scheduling policies to define the RPO for your applications. These policies allow you to automate backups at regular intervals, such as every few minutes, hours, or once a day. This simplifies the implementation of RPO. Continuous data protection (CDP) ensures that any changes made to your system or application are instantly backed up or replicated. This addresses the risk of data loss between scheduled backups and allows you to achieve zero RPO. However, enabling CDP for critical workloads may impact performance and stability due to increased resource utilization. As a result, CDP is commonly used for file-level backups.

Near continuous data protection can be configured to achieve near-zero RPO by running backups at frequent intervals. This approach comes close to the effect of CDP and can be utilized for image-level backup/replication using snapshot-based technology or similar methods. Most backup and disaster recovery solutions on the market enable you to achieve near-zero RPO of less than 15 minutes for your critical systems.

Instant Recovery Capabilities

To meet near-zero RTO goals, it is essential to have instant recovery capabilities within your Backup and Disaster Recovery plan. One crucial capability is the ability to boot a backed-up machine instantly from the backup storage as a fully functional virtual machine, enabling seamless continuation of business operations. By starting a virtual machine in the virtual environment directly from the latest backup or a specific point in time, using encrypted and compressed backup data, you can have your critical system up and running within minutes. This ensures business continuity while achieving near-zero RTO. With this approach, downtime is minimized, allowing your Tier 1 mission-critical systems to continue operating without any disruptions. Subsequently, you can migrate the instantly booted virtual machine to production for a permanent recovery.

Granular Recovery

Granular recovery plays a significant role in a backup and disaster recovery plan. It provides the ability to restore only the necessary data. This functionality allows you to selectively restore specific files or application items directly from the backup. In the event of accidentally deleting a file, you can easily select and restore that particular file. Similarly, you can promptly restore individual emails or mailboxes without the need to recover the entire database or application. By leveraging granular recovery, you can achieve an RTO of a few minutes. This approach saves time and resources since restoring an entire machine is not required for recovering individual items.

Live Replication with Failover

Live replication allows you to create an exact duplicate of your production workloads at another location and frequently replicate any changes to the replica machine, achieving near-zero RPO.

In the event of an outage or corruption affecting your source machine, you can immediately initiate a failover operation that seamlessly transitions your production operations to the replica machine. This switch occurs without any downtime or disruption, enabling you to continue your business operations while meeting your near-zero RTO objectives. When both RTO and RPO are nearly zero, leveraging replication and failover functionalities ensures your production workloads are always available.

Offsite Copy for Disaster Recovery

Disasters are unpredictable, and even local backups can become inaccessible during a full-site failure, putting your business at risk of data loss.

To mitigate this risk, it is essential to have a disaster recovery plan that involves creating an additional copy of your backups and storing it in a remote location, such as a local data center or a public cloud. By having offsite backups, you can recover your systems in the event of a disaster and easily achieve your business recovery objectives.

Risks of Ignoring RTO and RPO Metrics
