Maximum Tolerable Downtime (MTD) - The MTD represents the total amount of time

or system outage, to which mission/business process data shall be recovered (given the

HOT / COLD site
A hot site is a DR location that is set up and ready to go -- that is, one can arrive and continue to work immediately. A hot backup site will have equipment set up with your current data available when you walk in, with all primary data center functions copied and maintained off site.
Unlike a hot site, which is available and running 24/7, a cold site is essentially available space with little, if anything, set up in it. When you arrive at a cold backup site, you need to set up the equipment, make all connections, load the software, etc. Until DR services are activated, only basic power, communication services and environmental controls for the IT system are installed.
