First Job at the Recovery Site

About this interactive

A disaster recovery plan covers who does what, how they communicate, the checklists for failing over, and redundancy within servers and between sites. The second site is chosen by how ready it is. - A hot site has all the equipment running and the data replicated to it, an exact duplicate. Failing over means making sure it is on, pointing things at it and turning the original site down. Recovery time is very short. - A warm site has the equipment set up, but the data is not live there. The team restores the data onto the waiting servers and brings them up. - A cold site is a place picked out, without the equipment set up. The team has to install the equipment and then restore the data, so recovery takes the longest. - A mobile site has the equipment installed on a truck, which can be driven to wherever it is needed. A quick test for a card: what is already at the site when the team arrives? Live data, servers waiting for data, an empty space, or a truck that still has to get there? Security+ lists hot, warm and cold sites, with geographic dispersion, under resilience and recovery.

What you'll learn

Tell a hot, warm, cold and mobile recovery site apart by the first job the recovery team does there
Relate how ready each site is, with live data, equipment waiting for a restore, an empty space or equipment on a truck, to how long recovery takes

Key terms

Hot Site: A fully operational duplicate facility with live systems and current data that can immediately assume workloads if the primary site fails, providing the fastest possible disaster recovery time.
Warm Site: A partially equipped recovery site with some infrastructure and recent data copies that requires additional setup before becoming operational, balancing cost and recovery speed.
Cold Site: A recovery site with little to no pre-installed equipment or live data that can take days to become operational but carries the lowest ongoing cost.
Mobile Site: A portable disaster recovery solution with IT equipment installed in a transportable unit such as a truck, deployable to any location.
Disaster Recovery Plan: A Disaster Recovery Plan is a documented set of procedures for restoring IT systems and data following a disruptive event, defining recovery time objectives, roles, and step-by-step recovery actions.
Disaster Recovery: The process and procedures for recovering IT systems and data following a disruptive event.
