Back Up & Save

Back Up Your Data

80% of computer users never back up their data. Do you?

Why back up? Why save? What if....

  • data is accidently deleted
  • the hard drive or disc drive fails
  • a device is lost or stolen
  • viruses, malware and intrusions compromise data
  • there is a natural disaster
  • children or other users access and delete

The 3-2-1 Back Up Rule

The simplest way to remember how to protect your data:

  • 3 copies of your data (a primary & two back ups)
  • on 2 different storage options/media options
  • with 1 existing off site/off line

3-2-1 storage is ideal but not always possible. Best practices require 3 copies and some physical separation between the copies.
