Often times when using a computer, there’s possibly a feeling of unease. What if you open a web page and download a Ransomware strain? What if you install a Windows Update that has a critical incompatibility with your machine? There’s a lot of possible issues facing the standard computer user, and backups play an integral role in ensuring that your machines and data are preserved and protected.

A common rule shared among the IT community in regards to data protection is the 3-2-1 Rule. If following this rule, this means you keep:

  • Three (or more) copies of important files and data
  • These copies should be saved on two seperate devices
  • One of these devices should be off-site

Why Is The 3-2-1 Rule So Important?

When using our computers we want to ensure that we’re minimizing risk. By doing so we can use our computers however we want and know that whether we’re downloading a Windows Update or an update to our favourite programs, we are able to back out of a precarious situation. The 3-2-1 Rule allows us to achieve this.

Utilizing Sector Mapping Technology

Creating a schedule where you’re able to create a scheduled backup with your favourite disk imager and sector mapping technology means that you’re able to recover your machine quickly. Utilizing instant recovery software in conjunction with your disk imager will ensure that you have a solution to get you back up and running quickly. Meaning that instead of the usually slow restore times of a disk imager, you can have a machine up and running in seconds. This isn’t meant as a replacement for your disk imaging solution, but as the 3-2-1 Rule illustrates, you’re best to incorporate a strategy that ensures that no matter what situation you may find yourself in, you’re still guaranteed to get back to an operating state and keep recent copies of your files and data.


Hopefully reading this has given you some level of insight into why many companies, organizations, and individual PC users are gravitating towards utilizing the 3-2-1 Rule. It’s a robust strategy for maintaining system and data integrity in the event of a catastrophic failure. Hopefully this will give you some ideas on how to build confidence with your backup strategies!
