3-2-1 Data Backup

The 3-2-1 backup rule is a minimum guideline to protect your data. Follow this simple rule and you’ll be well protected to survive when (not if) a problem occurs.


Keep 3 Copies of Your Data

This is a minimum. You should have the original files along with two backup copies. Your original “working files” are considered copy number 1.


Use 2 Different Storage Devices

Your backups need to be separate from your main copy. If you simply copy them to a different folder on the same computer, you’ll likely lose both copies at once. Get an external drive for backup and store it somewhere safe.


Have 1 Backup Offsite

Make sure you have a second backup offsite. This can be an automatic cloud backup service. It can also be an external drive stored at a separate location such as your work or home. You want to be sure your data can survive a fire or flood.

This is a minimum backup strategy. Some files may need to be mirrored between multiple computers also. It’s important to automate this as much as possible because humans forget to do it. You should have reports and monitor those reports. It’s easy to set up an automated system and then forget about it while it silently fails.

If your data is extremely important, it’s sometimes helpful to hire a consultant to manage it for you and provide periodic reports to be sure it’s handled professionally.
