RTO VS RPO: Definition And Differences

Have you heard of RTO and RPO before?

Definition of RTO and RPO

First, the Recovery Time Objective (RTO) corresponds to the time that a system is expected to recover after a certain failure. It measures the time it will take to restore service and return to normal after experiencing an interruption.

The RTO is to be used as a guide for system recovery planning. For this reason, it is essential to set a realistic RTO and ensure that the necessary resources and recovery plan are in place so that it can be met.

Due to its characteristics, RTO is vital in business planning since it helps to minimize the impact of system failures and to ensure that the business can continue to function uninterrupted and effectively even in the event of disasters.

On the other hand, there is the Recovery Point Objective (RPO). This other concept, for its part, refers to the point at which the last backup of the system was made before a failure. Therefore, it is vital since it allows us to return to that point in the system as if nothing had happened.

The RPO, unlike the RTO, measures the time between the last backup and the moment of failure. This way, you can instantly know how much information has been lost.

Due to its importance, it is essential that companies set a realistic RPO and that they verify that backup copies are made with the necessary frequency to be able to comply with it. Due to its characteristics, RPO is considered a key concept in data protection since it helps minimize data loss in failures or disasters.

Differences between them

As for the differences between RTO and RPO, they do exist. Although both can and are used as guides, they have different characteristics.

RTO and RPO relate to data recovery in the event of a disaster or failure of a computer system. RTO covers the expected time the system will recover after a failure to know when it will return to normal after an interruption. While RPO measures the time elapsed between the last backup and the moment of failure, allowing the calculation of the lost information. That is why they are complementary and necessary.

How to calculate them?

To calculate RTO and RPO, several factors must be taken into account.

One has to do with the dependency of the business on the system, and the time it can be down if it is essential or lousy because you will need a lower RTO and RPO.

The amount of available resources can also affect system recovery time and RTO. Therefore, it must be calculated based on the resources available to the company.

Backup frequency is another important point that affects RPO. The more frequent the backups, the lower the RPO will be. That is why it is important to make regular backup copies; the more, the better.

Another factor to consider is the volume of data to be recovered since the more files the system will take to recover the information affecting the RTO.

Therefore, try to consider these factors and set realistic and achievable goals. Then it only remains to design the plans and the resources needed to fulfil them.

RTO and RPO targets for restoring cloud applications

When it comes to restoring applications in the cloud, the objectives may vary depending on two main aspects: the company and the cloud service provider.

The volume of data can certainly interfere with the time needed to restore the application, affecting the RTO. Therefore, the higher the volume, the greater the frequency with which backup copies are made, which we already told you affects RPO. The more frequently, the lower the RPO, which is why taking it as a goal is important.

Sometimes little is said about the cloud service provider, but RTO and RPO goals may also depend on recovery options and guarantees offered by the cloud service provider itself. That is why it is always important to choose a trusted provider.

Do you have any doubts left? We hope you have mastered these concepts and can apply them successfully in your business. Remember the importance of making backups periodically.
