What Is 3-2-1 Backup Strategy?

The 3-2-1 backup strategy is one of the best-known methods to copy data backups, which is commended by information security professionals, as well as government authorities. The rule is: create at least three copies of your data, and store two backup copies on different storage media, keep one of them offsite. To clarify, let’s take a look at each point of this rule.

3 - Create at least 3 copies of your data

In addition to the original copy, you should always have at least 2 backup copies of your data. More copies of your backup mean lower risk of losing everything.

2 - Store data on 2 different devices

Backing up to the same physical devices or same storage array is at risk of losing original data and backups at once. Therefore, you are recommended to store two backups on 2 different storage types like external HDDs/SSDs, USB flash drives, portable drives, SD cards, CD/DVD discs, etc.

1- Keep 1 copy of the data offsite

Storing data offsite means you have a clear and physical separation of your data, which can prevent you lose all data and backup versions in some situation like natural disasters. You can keep 1 copy of your data on cloud drive, NAS or network share.
