The 3-2-1 Backup Rule: The Simple Way to Protect Your Data
Every Thursday morning on KFGO, we talk about real-world technology topics that affect your home, your family, and your business. This week’s segment focused on something that doesn’t get much attention until it’s too late. Backups.
Most people think they are backed up. Many are not. The good news is that there is a simple, proven rule that works for almost everyone.
It’s called the 3-2-1 backup rule.
What Is the 3-2-1 Backup Rule?
The 3-2-1 rule is a basic framework for protecting your data. It applies whether you are backing up a single home computer or an entire office network.
3 copies of your data
You should always have:
- Your original data
- Two additional backup copies
Why this matters
Files get deleted by accident. Hard drives fail. Ransomware happens. Having multiple copies gives you options when something goes wrong.
2 different types of storage
Your backups should not all live on the same kind of device.
Examples:
- Your computer or server
- An external hard drive or network storage
- Cloud storage
Why this matters
If all your backups are on the same type of device and that device fails, everything fails with it.
1 copy stored offsite
At least one backup should be stored somewhere else.
Examples:
- Cloud backup
- A backup stored at another physical location
Why this matters
Fire, flooding, theft, or power damage can take out everything in one place. Offsite backups protect you from physical disasters.
What the 3-2-1 Rule Looks Like in Real Life
For a home user
- Files on your computer
- A local backup to an external drive or small NAS
- A cloud backup for offsite protection
For a business
- Servers or workstations
- On-site backup device for fast restores
- Encrypted cloud backup for offsite recovery
Same rule. Different scale.
Why Backups Fail for Most People
Most backup failures happen because:
- Backups are never tested
- Only one copy exists
- Everything is stored in one location
- No one is monitoring whether backups are still running
A backup that has never been tested is just a hope.
