Ransomware has changed its method
Ransomware used to encrypt your files and demand payment to unlock them. A good backup was often enough to recover. That is no longer the case.
Today, attackers practice double extortion: they steal your data first, then encrypt it. Even with a perfect backup, they threaten to publish your confidential information if you do not pay. Some groups add a third layer by contacting your clients or partners directly.
Why traditional backups are no longer enough
Attackers know that backups are your safety net. So they target them first. They hunt for your backup servers, delete the copies and disable alerts before launching the encryption. A backup reachable from the network is a vulnerable backup.
The 3-2-1-1-0 rule
A solid strategy in 2026 fits in this formula:
The key point is the immutable 1. An immutable backup cannot be changed or deleted for a set period, even with administrator access. That is exactly what puts your data beyond an attacker's reach.
The test everyone forgets
A backup you have never restored is not a backup, it is an assumption. The zero in the formula is the most neglected: you must restore regularly to confirm that your copies are usable and that your team knows how to do it under pressure.
