Cold Vs. Warm Vs. Hot

Dear DR Dan,

What’s the difference between a cold site, warm site, and hot site?

Newbie in New York

Hi Newbie,

That's a good question. Here's the short answer: A cold site is not much more than an empty warehouse where you store your '57 Chevy. A warm site is a warehouse with power, phone, raised floor, "empty" servers, and air conditioning, but, alas, no OS or data. A hot site is a true duplicate of your datacenter where you can recover in minutes, if not seconds.

The "warmer" you go, the more expensive it is.

Hope this helps.

DR Dan
