QTIP: What is the 3-2-1 rule?
Posted on March 8th, 2018
Data backup is more complex than ever for computer users as we ponder how to protect our data in local, virtual, and cloud storage environments. To meet this challenge all computer users need a realistic data protection plan so that at least one copy of their critical data survives if disaster strikes. How do you begin?
IT experts recommend the 3-2-1 rule: Make three copies of every piece of important data, store that data in two different formats and keep one copy offsite. Here’s the straight and simple:
- Three copies ensure that no single event will wipe out all the data.
- Two formats includes an internal drive plus external media (disk, tape, network, cloud, etc.)
- One copy offsite protects data against a physical disasters like theft, fire or flooding.
Computer hard drives will fail. Mobile devices will be damaged and lost. Storage media will be damaged, lost, and fail.
Data loss isn't a question of if, but when. The sooner we implement a data protection plan, the faster we’ll be back in business after a technology failure.
It’s as easy as 3-2-1.
