What does the 3-2-1 backup rule mean for businesses?

The 3-2-1 rule recommends keeping three copies of your data, including the original, across two different storage media, with one copy stored at a separate location. This reduces the risk of a device failure or a physical incident affecting every copy.

Build your backup plan around the amount of data loss you can tolerate (RPO) and the time you aim to restore operations (RTO). Protect your backups against deletion and attacks, and confirm they are usable through restore tests.
