In modern business operations, system availability and business continuity are critical. Any IT failure, data center crash or catastrophic event can affect business operations and even lead to serious financial losses. As a result, organizations need to have a clear Disaster Recovery (DR) plan in place, with the Recovery Time Objective (RTO) being a key metric that determines how quickly the business needs to be restored after an outage in order to avoid serious impact.

What is RTO (Recovery Time Objective)?

The Recovery Time Objective (RTO) refers to the amount of time an IT system, application, or business process must be restored after a disaster or failure to keep the business running without causing serious damage or impacting the customer experience.

Simply put, RTO objective addresses the question:

“How long must the business be restored?”

Different organizations and business systems have different RTO objective requirements. For example:

Bank transaction system: RTO may be only a few seconds to a few minutes, as a prolonged downtime can affect the safety of customer funds.

E-commerce platforms: recovery time objective may be 1-2 hours, otherwise a large number of orders may be missed and customer trust lost.

Internal office systems: RTO may allow 4-8 hours, as a short outage will not directly affect the core business.

Why is RTO important?

Developing a sound RTO is crucial for businesses and it can help:

Reduce losses from business interruptions: prolonged downtime can lead to lost customers, reduced orders, and even affect the reputation of the business.

Optimize disaster recovery scenarios: A properly set RTO allows businesses to invest in the right IT infrastructure without overspending.

Ensure compliance: Certain industries (e.g., financial, healthcare) have strict RTO regulations and organizations must adhere to compliance requirements.

Enhance customer satisfaction: The ability for organizations to recover systems quickly will reduce customer complaints and improve user experience.

Disaster recovery strategies under the influence of RTO

Different RTO objectives require different disaster recovery strategies. The following are typical recovery scenarios with applicable RTO timeframes:

RTO Time

Disaster Recovery Program

Applicable Business

Seconds - minutes

High Availability Architecture (HA), real-time hot standby, automatic failover

Banks, stock exchanges, medical systems

1 - 4 hours

Incremental backup + fast recovery, cloud disaster recovery solution

E-commerce, large enterprise IT systems

4 - 12 hours

Regular backup, manual recovery, cloud storage + remote recovery

On-premises applications, file storage

More than 12 hours

Traditional backup (tape/cloud archive), off-site disaster recovery

Non-critical data, historical archived data

RTO and RPO difference

In disaster recovery planning, in addition to RTO, there is another key metric called Recovery Point Objective (RPO), which defines the maximum amount of data an organization can afford to lose after a disaster.

Both RTO and RPO are measured using time. For RTO time, it is the time from disaster to service recovery, which also includes data recovery time. For RPO time, it is the time between the disaster and the last backup of the data.

Although both RTO and RPO use time as a metric, they are used for different purposes:

RTO focuses on the availability of an application or system, and while it includes the time for data recovery, it is more descriptive of the time limit for application downtime.

RPO is concerned with data integrity and describes the maximum data loss limits that can be tolerated. For example, the unavailability of a business system service can result in financial losses, but if the loss is of customer transaction data, the resulting losses can be even more catastrophic.

When developing a disaster recovery plan for your organization, you need to consider both RTO and RPO objectives. However, there are differences in the costs of RTO and RPO objectives. The cost of maintaining a demanding RTO goal can be higher than an RPO goal because RTO involves the entire business infrastructure, not just the data.

To achieve an RPO goal, all that is required is to perform data backups at the correct intervals, which can be easily automated, so an automated RPO strategy is easy to implement. On the other hand, a fully automated RTO policy is more complex to implement because RTO involves restoring all IT operations.

Both recovery time and recovery point objective are important when developing a disaster recovery plan. Business scenarios vary from enterprise to enterprise, which requires choosing the right RTO and RPO objectives based on the actual situation in order to maximize the economic benefits.

How to set a reasonable RTO?

Setting RTO requires comprehensive consideration of business requirements, technical realization and cost, and the main steps are as follows:

① Business Impact Analysis (BIA)

Identify key business systems and assess the impact of their downtime on the enterprise.

For example, the RTO for an order system may take one hour, while the RTO for an internal time and attendance system may be 24 hours.

② Assess IT Infrastructure

Ensure that existing backup and recovery capabilities can meet the RTO requirements.

For example, if the RTO is set at 10 minutes and the backup recovery takes 1 hour, an upgrade program is required.

③ Calculate cost and feasibility

High-availability solutions (e.g., dual live data centers) are costly and suitable for critical operations.

Regular backup + fast recovery solution can be used for general business to reduce cost.

④ Regular testing and optimization

Ensure that RTO objectives can be achieved in a real environment through regular disaster recovery drills (DR Drill).

Adjust the strategy based on the test results, e.g., optimize the backup recovery speed and improve the failover process.
