There’s no particular approach to implementing the 3-2-1 backup rule. That’s why it’s considered a best practice to upload at least one file to an external offsite platform like the cloud.

The 3-2-1 backup strategy encourages you to back up your data in remote locations where teams for other cities or countries can create further copies. An office fire or other natural disaster, for example, can destroy the data in one fell swoop. There’s always some risk of hardware malfunction and damage to physical storage devices, so keeping all your backup devices in one place is not recommended.

In worst-case scenarios, if one backup hard drive fails, the other will have your data safe and sound. The two locations or devices can be external hard drives, UBSs, magnetic storage devices, network-attached storage (NAS) or others. This step is the “2” in the 3-2-1 methodology.

The set can have one primary production copy-production in this case referring to data that’s required for day-to-day business activities-and two copies. The “3” in the 3-2-1 backup rule tells us to save three copies of data in unique places, away from each other. So, breaking it down from the bottom, the 3-2-1 backup rule works as follows: 3. The data is stored on at least two different devices, and one data copy is kept on the offsite device for disaster recovery. The backup strategy requires you to have three copies of data-your production data and two backup copies. The method saves different copies of data on different levels, devices and locations.
