What is the 3, 2, 1 – 1 Backup Strategy?

The backup solutions have been used for decades looking to have protected data, although they were not always reliable, for the same reason and with the experience that was given over the years, have come to define the best practices in this area and this has developed a strategy that is called “The Strategy 3, 2, 1 – 1”, which means that there are 3 maxims on the subject of the BackUps of the data:


  • You must have 3 copies of your data, the one that is in operation, plus two additional copies.


  • The 2 additional copies must be in two different media, disk, and cloud.


  • 1 of the 2 copies must be in an external site to the main site, a branch office or in the cloud, or in a vault, etc.

However, now due to Ransomware attacks and other types of hacks, an additional copy is increased, but in an immutable system, hence the extra “1” added to the strategy.

What is the goal of the 3, 2, 1 - 1 Strategy?

The goal of this backup rule is to ensure that if one backup fails, you have other backups to protect your data. Since, backups are essential for the continuity of business operations, and the 3, 2, 1 -1 backup rule offers many additional advantages, which are:


  • Distribute the location of backups.


  • No dependency on a single copy.


  • Increased data protection.

As technology advances, companies evolve, and it is increasingly important to have reliable backup solutions. The 3, 2, 1 – 1 strategy rule helps you know how to protect the data that is essential and ensures that you have a solid backup plan in place.

Why is it important to make backups?

Making a copy of the information and systems that the company manages and uses should be a priority in every business to ensure that, in the event of any problem with the data or interruption in the work processes, the copy can be restored and minimize the damage caused or the time lost.


A complete, differential and incremental backup is the best way to guarantee business continuity, and by applying a method such as the 3, 2, 1 -1 rule, you will always have a copy ready to be recovered, regardless of the type of incident (external or internal) that has occurred.


Therefore, this method must necessarily be accompanied by an internal policy of awareness and education in digital hygiene of all employees, transversally in all areas of the company, and the formation of leadership positions that can act quickly and make decisions in case of a cyberattack.


This whole process can be a positive response on the part of the organizations. If there is prior preparation, there is no reason to put at risk the integrity of employees and customers, nor the reputation of the organization, nor the obligation to pay a ransom of millions of dollars. A Modern Protection strategy proves to be an important competitive advantage in an increasingly adverse and challenging market, to take care of one of the most precious assets: data.
