Business data backup – the 3-2-1 strategy and ransomware protection
3-2-1 backup strategy: 3 copies of data, 2 different media, 1 off-site. Automated backup, cloud vs local, recovery testing and ransomware protection.
Imagine waking up to a ransomware note. With a proper backup, you restore and keep working. The 3-2-1 strategy is the simplest way to sleep well at night.
What is the 3-2-1 backup strategy? 🛡️
3 copies of data, 2 different media types (e.g. external drive + cloud), 1 copy off-site. This ensures that even a fire in your office won't destroy all your data.
⛔ MYTH: "Backup once and it works forever"
FACT: Backups need regular testing. Drives fail, cloud services go down, backups get corrupted. Test your restore process at least once per quarter. A backup you haven't tested is a backup that doesn't exist.
Automated backup is essential. Combine cloud (Backblaze, AWS S3) for daily use with local backup (external drive, NAS) for fast recovery. Encrypt all backups, especially those containing personal data.

Frequently Asked Questions
- Is cloud backup safe against ransomware?
- Yes, if the backup is isolated from your network. Use immutable storage and versioning. Even if ransomware encrypts everything, you have a clean copy from before the attack.
