What is the 3-2-1 Backup Rule and its Different Variations?

The 3-2-1 Data Backup Strategy is a best practice for securing important data. It involves having three copies of the data, stored on two different types of media, with one copy stored off-site. To implement this rule, an informative article can be consulted that explains the 3-2-1 Backup Rule in detail.

In addition to the standard 3-2-1 rule, there are variations such as:
  • 4-3-2-1, which includes a fourth copy of data on a different type of media and a second off-site location.
  • 3-2-1-1-0, which includes regular testing of backups.
