3-2-1 BACKUP

Sep 24, 2021

Have you heard of the backup rule 3, 2, 1?

The concept of the rule came from the American photographer Peter Krogh about 20 years ago. The innovation was very important for the world of photography and remains timeless even today. During these 20 years, 3-2-1 has been a good tool for evaluating data risk exposure. It may have started in CD backups but has evolved into TB drives and cloud storage. As much of our lives and our livelihoods are stored in digital form, with threats of malicious code constantly increasing, it is important for everyone to have a framework for assessing vulnerabilities, says Krogh.

But what does it stand for then? It stands for the following:

There must be 3 copies of data
On 2 different media
With 1 copy off site

This is a rule worth living by, for everyone, companies as individuals!
