The 3-2-1 Backup Methodology
What is It?
The 3-2-1 backup methodology is a widely accepted approach to ensure data protection and recovery in case of a disaster or data loss. It involves creating three copies of your data, storing them on two different types of storage media, and keeping one copy offsite.
Here’s a breakdown of each step:
1. Three copies of your data – Create three copies of your data to ensure redundancy. One is the original data, while the other two copies are backups. This means you have multiple copies of your data to rely on in case one copy becomes corrupted or lost.
2. Two different types of storage media – Store your data on two different types of storage media, such as an external hard drive and/or network attached storage (NAS) and a cloud-based storage solution. This ensures that if one storage medium fails, you still have a backup on another medium.
3. One copy offsite – Keep one copy of your data offsite, preferably in a different location from where your primary data is stored. This can be achieved by using cloud-based storage or physically transporting an external hard drive or other backup media to a different location.
Following the 3-2-1 backup methodology provides multiple layers of redundancy and protection for your data, ensuring that you can quickly recover your data in case of a disaster or data loss.
There are extensive options for both storage media and offsite locations solutions it depends on backup size which directly affects on-going costs and management of.
