We live in a digital world, where the only copy of our irreplaceable photos or important business data sits on a mechanical hard drive that can fail at any point without warning. Yikes!
Data loss can be devastating personally and professionally, and although data recovery is sometimes possible, the process is expensive and can’t always recover all of your files.
Creating a data backup plan can save you time and money if you have a hard drive crash. It may seem complicated, but it can be done fairly easily using the 3-2-1 backup strategy.
The 3-2-1 Backup Strategy
The 3-2-1 backup strategy is made up of three rules, which are:
- Three copies of your data- Copy 1 is your original data (your primary copy). For most people, this data is located on the C drive of their computer. You should also have at least two backup copies of this data.
- Two different storage types- Both backup copies should be kept on two separate storage types to minimize the chance of failure. Storage types could include a USB flash drive, internal hard drive, external hard drive, removable storage drive, DVD, tape or cloud backup.
- One copy offsite- At least one backup copy should be located offsite, away from your primary copy. This protects you from a natural disaster that could destroy all the local copies.
For example, let’s say your files are on the hard drive on your home computer. For your first backup copy, you can use an external hard drive, which you can easily access if you need to retrieve a file. You could then set up a cloud backup as your second (archive) backup copy.
If your computer hard drive fails, you can get your files back from either of your two backups. The external hard drive should be your first choice, because copying is much faster via USB cable than downloading from the cloud over your internet connection. But in the event your house catches on fire, or you have a power surge that wipes out both the computer and the external drive, that cloud storage backup is going to be a lifesaver (and worth every penny).
