The 3-2-1 Backup Rule Every Business Should Follow

Let me ask you a scary question: if your computer died right now — hard drive failure, ransomware attack, coffee spill, whatever — how much would you lose? A day’s work? A year’s worth? Everything?

Now the really scary question: are you sure your backups would actually save you?

Backups are your safety net, but only if they’re done right. Here’s what a good backup strategy looks like.

Follow the 3-2-1 rule

Keep three copies of your important data, on two different types of storage, with one copy stored offsite or in the cloud. That way, no single disaster — fire, flood, theft, or ransomware — can wipe out everything.

Automate it

If backups depend on someone remembering to do them, they won’t get done. Set it and forget it.

Test your backups

This is the part most people skip. A backup you can’t restore is worthless. When’s the last time you actually tried recovering a file?

Ransomware attackers are counting on you not having backups. Hardware fails eventually — it’s not a matter of if, but when. Don’t learn this lesson the hard way.

Common questions

Isn’t OneDrive or Dropbox already a backup?

Not quite. File sync is great, but it faithfully syncs everything, including mistakes. Delete a file and the deletion syncs. Get hit with ransomware and the encrypted files can sync too. Version history and recycle bins help, but they have limits and expiration windows. Sync is convenience. A real backup is a separate, protected copy you can restore from after something goes wrong.

How often should backups run?

For business data, daily is the floor. Ask yourself how much work you can afford to redo. If losing a full day of invoices, orders, or case files would hurt, back up more often. Servers and line-of-business databases often warrant backups every few hours.

What actually counts as the offsite copy?

Anything that survives a disaster at your office. Cloud backup is the easiest answer for most businesses. An external drive in a desk drawer next to the server does not count, because the fire, flood, or thief that takes the server takes the drive too.
