In a ransomware attack, the difference between a catastrophe and a minor inconvenience often comes down to one thing: whether you have a working backup.
The 3-2-1 rule is a classic for a reason: 3 copies, on 2 different media, 1 off-site (offline or immutable).
Why the offline copy is critical
Modern ransomware deliberately seeks out and encrypts backups. If yours are connected and accessible, they fall along with everything else. An offline or immutable copy is untouchable.
3-2-1copies · media · off-site — the minimum for real resilience.
Backup best practices
- 3 copies of your data, 2 media types, 1 offline/immutable
- Regularly test your restores — not just your backups
- Encrypt your backups
- Automate, so you don't rely on human memory
How to protect yourself
A backup you haven't tested restoring from is just hope. Schedule regular restore tests — the day of an attack is not the moment to discover your backup is corrupted.
