3-2-1-1-0ģ-2-1-1-0 is built on the same foundation as the 3-2-1 rule however it goes a step further by stipulating an additional “Air Gapped” or offline backup and adding a check process to ensure all backups have zero errors. Over the years there have been multiple variations of the 3-2-1 rule such as 3-2-1-1-0 and 4-3-2 however these have their own range of issues including costs and time to manage the infrastructure that goes with these strategies. However over the years where threats have become more aggressive and reliance on IT grows this rule is no longer enough. The idea of 3-2-1 backup rule is to protect against a single disaster such as a fire or flood in the office, in this situation you would be able to recover from your offsite backup. One of the key parts of a managed service is to prepare for downtime or a disaster event. As businesses develop, most will partner with an MSP or Managed Service Provider to ensure that their IT infrastructure runs smoothly.

But today, the gold standard is evolving. The 3-2-1 rule still has value, especially for businesses who aren’t backing up at all. Most businesses now create and deploy a BCDR or Business Continuity & Disaster Recovery Plan which not only ensures reliable backups of data but also focuses on time of recovery. However as variations of this rule have developed and businesses try to ensure a more resilient data model, the rule has become just 1 part of an overall protection plan. Backup Vs Business Continuity & Disaster Recovery (BCDR) photographer Peter Krogh in the early 2000’s and has gone on to stand the test of time and is still relevant today. The 3-2-1 backup rule states that you should have 3 copies of your data, 2 different backup formats, and 1 backup stored offsite.
