Backups aren’t enough: the 3-2-1 rule and disaster recovery

Many businesses believe they have backups, until a crisis reveals the backup is corrupt or incomplete. An untested backup is just a feeling of security.

The 3-2-1 rule is simple but effective: keep at least 3 copies of your data, on 2 different media, with 1 copy off-site.

A disaster recovery plan defines not only the backup but how fast (RTO) and with what data loss (RPO) you can bring systems back up.

No plan is complete without regular recovery drills.
