Back Up & Save
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.
